BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES AREPERFORMED ONLY BY QUALIFIED INDIVIDUALS.

WARNING

ELECTRIC AND MAGNETIC FIELDSmay be dangerous

2.a. Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). Welding current creates EMF fields around welding cables and welding machines

2.b. EMF fields may interfere with some pacemakers, andwelders having a pacemaker should consult their physicianbefore welding.

2.c. Exposure to EMF fields in welding may have other healtheffects which are now not known.

2.d. All welders should use the following procedures in order tominimize exposure to EMF fields from the welding circuit:

2.d.1. Route the electrode and work cables together - Securethem with tape when possible.

2.d.2. Never coil the electrode lead around your body.

2.d.3. Do not place your body between the electrode andwork cables. If the electrode cable is on your right side, the work cable should also be on your right side.

2.d.4. Connect the work cable to the workpiece as close aspossible to the area being welded.

2.d.5. Do not work next to welding power source.

1.h. To avoid scalding, do not remove theradiator pressure cap when the engine ishot.

CALIFORNIA PROPOSITION 65 WARNINGS

ARC RAYS can burn.4.a. Use a shield with the proper filter and cover

plates to protect your eyes from sparks andthe rays of the arc when welding or observingopen arc welding. Headshield and filter lensshould conform to ANSI Z87. I standards.

4.b. Use suitable clothing made from durable flame-resistantmaterial to protect your skin and that of your helpers fromthe arc rays.

4.c. Protect other nearby personnel with suitable, non-flammablescreening and/or warn them not to watch the arc nor exposethemselves to the arc rays or to hot spatter or metal.

ELECTRIC SHOCK cankill.3.a. The electrode and work (or ground) circuits

are electrically “hot” when the welder is on.Do not touch these “hot” parts with your bareskin or wet clothing. Wear dry, hole-free

gloves to insulate hands.

3.b. Insulate yourself from work and ground using dry insulation.Make certain the insulation is large enough to cover your fullarea of physical contact with work and ground.

In addition to the normal safety precautions, if weldingmust be performed under electrically hazardousconditions (in damp locations or while wearing wetclothing; on metal structures such as floors, gratings orscaffolds; when in cramped positions such as sitting,kneeling or lying, if there is a high risk of unavoidable oraccidental contact with the workpiece or ground) usethe following equipment:

• Semiautomatic DC Constant Voltage (Wire) Welder.• DC Manual (Stick) Welder.• AC Welder with Reduced Voltage Control.

3.c. In semiautomatic or automatic wire welding, the electrode,electrode reel, welding head, nozzle or semiautomaticwelding gun are also electrically “hot”.

3.d. Always be sure the work cable makes a good electricalconnection with the metal being welded. The connectionshould be as close as possible to the area being welded.

3.e. Ground the work or metal to be welded to a good electrical(earth) ground.

3.f. Maintain the electrode holder, work clamp, welding cable andwelding machine in good, safe operating condition. Replacedamaged insulation.

3.g. Never dip the electrode in water for cooling.

3.h. Never simultaneously touch electrically “hot” parts ofelectrode holders connected to two welders because voltagebetween the two can be the total of the open circuit voltageof both welders.

3.i. When working above floor level, use a safety belt to protectyourself from a fall should you get a shock.

3.j. Also see Items 6.c. and 8.

iiSAFETYii

FUMES AND GASEScan be dangerous.5.a. Welding may produce fumes and gases

hazardous to health. Avoid breathing thesefumes and gases. When welding, keepyour head out of the fume. Use enoughventilation and/or exhaust at the arc to keep

fumes and gases away from the breathing zone. Whenwelding with electrodes which require specialventilation such as stainless or hard facing (seeinstructions on container or MSDS) or on lead orcadmium plated steel and other metals or coatingswhich produce highly toxic fumes, keep exposure aslow as possible and within applicable OSHA PEL and ACGIH TLV limits using local exhaust or mechanicalventilation. In confined spaces or in some circum-stances, outdoors, a respirator may be required.Additional precautions are also required when weldingon galvanized steel.

5. b. The operation of welding fume control equipment is affectedby various factors including proper use and positioning ofthe equipment, maintenance of the equipment and the spe-cific welding procedure and application involved. Workerexposure level should be checked upon installation andperiodically thereafter to be certain it is within applicableOSHA PEL and ACGIH TLV limits.

5.c. Do not weld in locations near chlorinated hydrocarbon vaporscoming from degreasing, cleaning or spraying operations.The heat and rays of the arc can react with solvent vapors toform phosgene, a highly toxic gas, and other irritating prod-ucts.

5.d. Shielding gases used for arc welding can displace air andcause injury or death. Always use enough ventilation,especially in confined areas, to insure breathing air is safe.

5.e. Read and understand the manufacturer’s instructions for thisequipment and the consumables to be used, including thematerial safety data sheet (MSDS) and follow youremployer’s safety practices. MSDS forms are available fromyour welding distributor or from the manufacturer.

5.f. Also see item 1.b.

FOR ELECTRICALLYpowered equipment.

8.a. Turn off input power using the disconnectswitch at the fuse box before working onthe equipment.

8.b. Install equipment in accordance with the U.S. NationalElectrical Code, all local codes and the manufacturer’srecommendations.

8.c. Ground the equipment in accordance with the U.S. NationalElectrical Code and the manufacturer’s recommendations.

CYLINDER may explodeif damaged.7.a. Use only compressed gas cylinders

containing the correct shielding gas for theprocess used and properly operatingregulators designed for the gas and

pressure used. All hoses, fittings, etc. should be suitable forthe application and maintained in good condition.

7.b. Always keep cylinders in an upright position securelychained to an undercarriage or fixed support.

7.c. Cylinders should be located:• Away from areas where they may be struck or subjected tophysical damage.

• A safe distance from arc welding or cutting operations andany other source of heat, sparks, or flame.

7.d. Never allow the electrode, electrode holder or any otherelectrically “hot” parts to touch a cylinder.

7.e. Keep your head and face away from the cylinder valve outletwhen opening the cylinder valve.

7.f. Valve protection caps should always be in place and handtight except when the cylinder is in use or connected foruse.

7.g. Read and follow the instructions on compressed gascylinders, associated equipment, and CGA publication P-l,“Precautions for Safe Handling of Compressed Gases inCylinders,” available from the Compressed Gas Association1235 Jefferson Davis Highway, Arlington, VA 22202.

WELDING and CUTTINGSPARKS cancause fire or explosion.6.a. Remove fire hazards from the welding area.

If this is not possible, cover them to preventthe welding sparks from starting a fire.

Remember that welding sparks and hotmaterials from welding can easily go through small cracksand openings to adjacent areas. Avoid welding nearhydraulic lines. Have a fire extinguisher readily available.

6.b. Where compressed gases are to be used at the job site,special precautions should be used to prevent hazardoussituations. Refer to “Safety in Welding and Cutting” (ANSIStandard Z49.1) and the operating information for theequipment being used.

6.c. When not welding, make certain no part of the electrodecircuit is touching the work or ground. Accidental contactcan cause overheating and create a fire hazard.

6.d. Do not heat, cut or weld tanks, drums or containers until theproper steps have been taken to insure that such procedureswill not cause flammable or toxic vapors from substancesinside. They can cause an explosion even though they havebeen “cleaned”. For information, purchase “RecommendedSafe Practices for the Preparation for Welding and Cutting ofContainers and Piping That Have Held HazardousSubstances”, AWS F4.1 from the American Welding Society(see address above).

6.e. Vent hollow castings or containers before heating, cutting orwelding. They may explode.

6.f. Sparks and spatter are thrown from the welding arc. Wear oilfree protective garments such as leather gloves, heavy shirt,cuffless trousers, high shoes and a cap over your hair. Wearear plugs when welding out of position or in confined places.Always wear safety glasses with side shields when in awelding area.

6.g. Connect the work cable to the work as close to the weldingarea as practical. Work cables connected to the buildingframework or other locations away from the welding areaincrease the possibility of the welding current passingthrough lifting chains, crane cables or other alternate cir-cuits. This can create fire hazards or overheat lifting chainsor cables until they fail.

6.h. Also see item 1.c.

6.I. Read and follow NFPA 51B “ Standard for Fire PreventionDuring Welding, Cutting and Other Hot Work”, availablefrom NFPA, 1 Batterymarch Park, PO box 9101, Quincy, Ma022690-9101.

6.j. Do not use a welding power source for pipe thawing.

PRÉCAUTIONS DE SÛRETÉPour votre propre protection lire et observer toutes les instructionset les précautions de sûreté specifiques qui parraissent dans cemanuel aussi bien que les précautions de sûreté générales suiv-antes:

Sûreté Pour Soudage A LʼArc1. Protegez-vous contre la secousse électrique:

a. Les circuits à lʼélectrode et à la piéce sont sous tensionquand la machine à souder est en marche. Eviter toujourstout contact entre les parties sous tension et la peau nueou les vétements mouillés. Porter des gants secs et sanstrous pour isoler les mains.

b. Faire trés attention de bien sʼisoler de la masse quand onsoude dans des endroits humides, ou sur un planchermetallique ou des grilles metalliques, principalement dans les positions assis ou couché pour lesquelles une grandepartie du corps peut être en contact avec la masse.

c. Maintenir le porte-électrode, la pince de masse, le câblede soudage et la machine à souder en bon et sûr étatdefonctionnement.

d.Ne jamais plonger le porte-électrode dans lʼeau pour lerefroidir.

e. Ne jamais toucher simultanément les parties sous tensiondes porte-électrodes connectés à deux machines à souderparce que la tension entre les deux pinces peut être letotal de la tension à vide des deux machines.

f. Si on utilise la machine à souder comme une source decourant pour soudage semi-automatique, ces precautionspour le porte-électrode sʼapplicuent aussi au pistolet desoudage.

2. Dans le cas de travail au dessus du niveau du sol, se protégercontre les chutes dans le cas ou on recoit un choc. Ne jamaisenrouler le câble-électrode autour de nʼimporte quelle partiedu corps.

3. Un coup dʼarc peut être plus sévère quʼun coup de soliel,donc:

a. Utiliser un bon masque avec un verre filtrant appropriéainsi quʼun verre blanc afin de se protéger les yeux du ray-onnement de lʼarc et des projections quand on soude ouquand on regarde lʼarc.

b. Porter des vêtements convenables afin de protéger lapeau de soudeur et des aides contre le rayonnement delʻarc.

c. Protéger lʼautre personnel travaillant à proximité ausoudage à lʼaide dʼécrans appropriés et non-inflammables.

4. Des gouttes de laitier en fusion sont émises de lʼarc desoudage. Se protéger avec des vêtements de protection libresde lʼhuile, tels que les gants en cuir, chemise épaisse, pan-talons sans revers, et chaussures montantes.

5. Toujours porter des lunettes de sécurité dans la zone desoudage. Utiliser des lunettes avec écrans lateraux dans leszones où lʼon pique le laitier.

6. Eloigner les matériaux inflammables ou les recouvrir afin deprévenir tout risque dʼincendie dû aux étincelles.

7. Quand on ne soude pas, poser la pince à une endroit isolé dela masse. Un court-circuit accidental peut provoquer unéchauffement et un risque dʼincendie.

8. Sʼassurer que la masse est connectée le plus prés possiblede la zone de travail quʼil est pratique de le faire. Si on placela masse sur la charpente de la construction ou dʼautresendroits éloignés de la zone de travail, on augmente le risquede voir passer le courant de soudage par les chaines de lev-age, câbles de grue, ou autres circuits. Cela peut provoquerdes risques dʼincendie ou dʼechauffement des chaines et descâbles jusquʼà ce quʼils se rompent.

9. Assurer une ventilation suffisante dans la zone de soudage.Ceci est particuliérement important pour le soudage de tôlesgalvanisées plombées, ou cadmiées ou tout autre métal quiproduit des fumeés toxiques.

10. Ne pas souder en présence de vapeurs de chlore provenantdʼopérations de dégraissage, nettoyage ou pistolage. Lachaleur ou les rayons de lʼarc peuvent réagir avec les vapeursdu solvant pour produire du phosgéne (gas fortement toxique)ou autres produits irritants.

11. Pour obtenir de plus amples renseignements sur la sûreté,voir le code “Code for safety in welding and cutting” CSAStandard W 117.2-1974.

PRÉCAUTIONS DE SÛRETÉ POURLES MACHINES À SOUDER ÀTRANSFORMATEUR ET ÀREDRESSEUR

1. Relier à la terre le chassis du poste conformement au code delʼélectricité et aux recommendations du fabricant. Le dispositifde montage ou la piece à souder doit être branché à unebonne mise à la terre.

2. Autant que possible, Iʼinstallation et lʼentretien du poste seronteffectués par un électricien qualifié.

3. Avant de faires des travaux à lʼinterieur de poste, la debranch-er à lʼinterrupteur à la boite de fusibles.

4. Garder tous les couvercles et dispositifs de sûreté à leurplace.

Output connections on some Power Waves® are madevia 1/2-13 threaded output studs located beneath thespring loaded output cover at the bottom of the casefront.

Most welding applications run with the electrode beingpositive (+). For those applications, connect the elec-trode cable between the wire feeder and the positive(+) output Twist-Mate terminal on the power source.Connect the other end of the electrode cable to thewire drive feed plate. The electrode cable lug must beagainst the feed plate. Be sure the connection to thefeed plate makes tight metal-to-metal electrical con-tact. The electrode cable should be sized according tothe specifications given in the output cable connec-tions section. Connect a work lead from the negative(-) power source output Twist-Mate terminal to thework piece. The work piece connection must be firmand secure, especially if pulse welding is planned.

For additional Safety information regarding the elec-trode and work cable set-up, See the standard "SAFE-TY INFORMATION" located in the front of theInstruction Manuals.

Excessive voltage drops caused by poor workpiece connections often result in unsatisfactorywelding performance.------------------------------------------------------------------------NEGATIVE ELECTRODE POLARITYWhen negative electrode polarity is required, such asin some Innershield applications, reverse the outputconnections at the power source (electrode cable tothe negative (-) Twist-Mate terminal, and work cableto the positive (+) Twist-Mate terminal.

When operating with negative electrode polarity the"Electrode Sense Polarity" DIP switch must be set tothe "Negative" position on the Wire Drive Feed HeadPC Board. The default setting of the switch is positiveelectrode polarity. Consult the Power Feed instructionmanual for further details.

OUTPUT CABLES, CONNECTIONS ANDLIMITATIONSConnect a work lead of sufficient size and length (pertable A.1) between the proper output terminal on thepower source and the work. Be sure the connection tothe work makes tight metal-to-metal electrical contact.To avoid interference problems with other equipmentand to achieve the best possible operation, route allcables directly to the work or wire feeder. Avoidexcessive lengths and do not coil excess cable.

When using an inverter type power source like thePower Waves®, use the largest welding (electrodeand work) cables that are practical. At least 2/0copper wire - even if the average output currentwould not normally require it. When pulsing, thepulse current can reach very high levels. Voltagedrops can become excessive, leading to poorwelding characteristics, if undersized weldingcables are used.-----------------------------------------------------------------------CABLE INDUCTANCE, AND ITS EFFECTSON PULSE WELDINGFor Pulse Welding processes, cable inductance willcause the welding performance to degrade. For thetotal welding loop length less than 50 ft.(15.24m), tradi-tional welding cables may be used without any effectson welding performance. For the total welding looplength greater than 50 ft.(15.24m)), the K1796 CoaxialWelding Cables are recommended. The welding looplength is defined as the total of electrode cable length(A) + work cable length (B) + work length (C) (SeeFigure A.3).

For long work piece lengths, a sliding ground shouldbe considered to keep the total welding loop length

VOLTAGE SENSINGThe best arc performance occurs when the PowerWaves® have accurate data about the arc conditions.Depending upon the process, inductance within theelectrode and work lead cables can influence theapparent voltage at the studs of the welder. Voltagesense leads improve the accuracy of the arc condi-tions and can have a dramatic effect on performance.Sense Lead Kits (K940-10, -25 or -50) are availablefor this purpose.

If the voltage sensing is enabled but the senseleads are missing, improperly connected, or if theelectrode polarity switch is improperly configured,extremely high welding outputs may occur.------------------------------------------------------------------------The ELECTRODE sense lead (67) is built into thecontrol cable, and is automatically enabled for allsemi-automatic processes. The WORK sense lead(21) connects to the Power Wave® at the four pin con-nector. By default the WORK voltage is monitored atthe output stud in the POWER WAVE® 355M. Formore information on the WORK sense lead (21), see"Work Voltage Sensing” in the following paragraph.

Enable the voltage sense leads as follows:

* The electrode voltage 67 sense lead is integral tothe control cable to the wire feeder.

Work Voltage SensingThe standard POWER WAVE® 355Mʼs default to thework stud (work sense lead disabled).

For processes requiring work voltage sensing, con-nect the (21) work voltage sense lead (K940) from thePower Wave® work sense lead receptacle to the workpiece. Attach the sense lead to the work piece asclose to the weld as practical, but not in the return cur-rent path of the electrode to the ground clamp. Enablethe work voltage sensing in the Power Wave®. (SeeDip Switch Settings and Locations in InstallationSection of this manual.)

ELECTRODE VOLTAGE SENSINGEnabling or disabling electrode voltage sensing isautomatically configured through software. The 67electrode sense lead is internal to the cable to thewire feeder and always connected when a wire feederis present.

Important: The electrode polarity must be config-ured at the feed head for all semi-automaticprocesses. Failure to do so may result in extreme-ly high welding outputs.-----------------------------------------------------------------------

POWER WAVE TO SEMI-AUTOMATICPOWER FEED WIRE FEEDER INTERCON-NECTIONS

The POWER WAVE® 355M and semi-automat icPower Feed family communicate via a 5 conductorcontrol cable (K1543). The control cable consists oftwo power leads, one twisted pair for digital communi-cation, and one lead for voltage sensing. The cablesare designed to be connected end to end for ease ofextension. The output receptacle on the POWERWAVE® 355M is on the case front. The input recepta-cle on the Power Feed is typically located at the backof the feeder, or on the bottom of the user interface.

Due to the flexibility of the platform the configurationmay vary. The following is a general description of thesystem. For specific configuration information, consultthe semi-automatic Power Feed instruction manual.

SYSTEM DESCRIPTION

The POWER WAVE® 355M and Power Feed M family ofproducts utilize a digital communication system calledArcLink. Simply put, ArcLink allows large amounts ofinformation to be passed at very high speeds betweencomponents (nodes) in the system. The system requiresonly two wires for communication, and because of itsbus-like structure, the components may be connected tothe network in any order, thus simplifying the system set-up.

Each "system" must contain only one power source.The number of wire feeders is determined by the typeof wire feeder. Refer to the wire feeder instructionmanual for details

CONTROL CABLE SPECIFICATIONSIt is recommended that genuine Lincoln control cablesbe used at all times. Lincoln cables are specificallydesigned for the communication and power needs ofthe Power Wave® / Power Feed® system.

The use of non-standard cables, especially inlengths greater than 25 feet(7.6m), can lead tocommunication problems (system shutdowns),poor motor acceleration (poor arc starting) and lowwire driving force (wire feeding problems).------------------------------------------------------------------------The K1543 series of control cables can be connectedend to end for ease of extension. Do not exceed morethan 100 feet (30.5 m) total control cable length.

WELDING WITH MULTIPLE POWERWAVES®

Special care must be taken when more than onePower Wave® is welding simultaneously on a sin-gle part. Arc blow and arc interference may occuror be magnified.

Each power source requires a work lead from thework stud to the welding fixture. Do not combine all ofthe work leads into one lead. The welding travel direc-tions should be in the direction moving away from thework lead as shown below. Connect all of the worksense leads from each power source to the workpiece at the end of the weld. (See Figure A.6)

For the best results when pulse welding, set the wiresize and wire feed speed the same for all the PowerWaves®. When these parameters are identical, thepulsing frequency will be the same, helping to stabilizethe arcs.

Every welding gun requires a separate shielding gasregulator for proper flow rate and shielding gas cover-age.

Do not attempt to supply shielding gas for two or moreguns from only one regulator.

If an anti-spatter system is in use then each gun musthave its own anti-spatter system.

In addition, the Power Feed® semi-automaticwire feeders may require optional equipment toaccess certain weld modes in the Power Wave®. Othermodels of Lincoln feeders, or any models of non-Lincoln wire feeders, cannot be used.

All welding programs and procedures are selectedthrough the Power Feed® M semi-automatic user inter-face

REQUIRED EQUIPMENTAny ArcLink compatible semi-automatic wire feedingequipment. Specifically, the semi-automatic PowerFeed® M family.

LIMITATIONS• Only ArcLink compatible Power Feed® M semi-

automatic wire feeders and users interfaces may beused. Other Lincoln wire feeders or non-Lincoln wirefeeders cannot be used.

• POWER WAVE® 355M Output LimitationsThe POWER WAVE® 355M will support maximumaverage output current of 350 Amps @ 60% dutycycle.

DUTY CYCLE AND TIME PERIODThe duty cycle is based upon a ten minute period. A60% duty cycle represents 6 minutes of welding and 4minutes of idling in a ten minute period.

WELDING ADJUSTMENTS

All adjustments are made on the system componentknown as the User Interface (Control Box), which con-tains the switches, knobs, and digital displays neces-sary to control both the Power Wave® and a PowerFeed® wire feeder. Typically, the Control Box is sup-plied as part of the wire feeder. It can be mounteddirectly on the wire feeder itself, or mounted separate-ly, as might be done in a welding boom installation.

Because the Control Box can be configured with manydifferent options, your system may not have all of thefollowing adjustments. Regardless of availability, allcontrols are described below. For further information,consult the Power Feed® wire feeder instruction manu-al.

• WFS / AMPS:In synergic weld ing modes (synergic CV, pulseGMAW) WFS (wire feed speed) is the dominant con-trol parameter, controlling all other variables. The useradjusts WFS according to factors such as weld size,penetration requirements, heat input, etc. The PowerWave® then uses the WFS setting to adjust its outputcharacteristics (output voltage, output current) accord-ing to pre-programmed settings contained in thePower Wave®.

In non-synergic modes, the WFS control behavesmore like a conventional CV power source whereWFS and voltage are independent adjustments.Therefore to maintain the arc characteristics, the oper-ator must adjust the voltage to compensate for anychanges made to the WFS.

In constant current modes (stick, TIG) this controladjusts the output current, in amps.

• VOLTS / TRIM:In constant voltage modes (synergic CV, standardCV) the control adjusts the welding voltage.

In pulse synergic welding modes (pulse GMAW only)the user can change the Trim setting to adjust the arclength. It is adjustable from 0.500 to 1.500. A Trim set-ting of 1.000 is a good starting point for most condi-tions.

• WELDING MODEMay be selected by name (CV/MIG, CC/Stick Crisp,Gouge, etc.) or by a mode number (10, 24, 71, etc.)depending on the Control Box options. Selecting awelding mode determines the output characteristics ofthe Power Wave® power source. For a more completedescription of the welding modes available in thePower Wave®, see the explanation following.

FRINGE PROCEDURESExcessively short or long electrode stick-outs mayfunction only on a limited basis, if at all.

MAKING A WELD

The serviceability of a product or structure utiliz-ing the welding programs is and must be the soleresponsibility of the builder/user. Many variablesbeyond the control of The Lincoln ElectricCompany affect the results obtained in applyingthese programs. These variables include, but arenot limited to, welding procedure, plate chemistryand temperature, weldment design, fabricationmethods and service requirements. The availablerange of a welding program may not be suitablefor all applications, and the build/user is and mustbe solely responsible for welding program selec-tion.------------------------------------------------------------------------

The steps for operating the Power Wave® will varydepending upon the options installed in the user inter-face (control box) of the welding system. The flexibilityof the Power Wave® system lets the user customizeoperation for the best performance.

First, consider the desired welding process and thepart to be welded. Choose an electrode material,diameter, shielding gas and process (GMAW, GMAW-P, etc.)

Second, find the program in the welding software thatbest matches the desired welding process. The stan-dard software shipped with the Power Waves® encom-passes a wide range of common processes and willmeet most needs. If a special welding program isdesired, contact the local Lincoln Electric sales repre-sentative.

To make a weld, the Power Wave® needs to know thedesired welding parameters. The Power Feed® (PF)family of feeders communicate settings to the PowerWave through control cable connection. Arc length,wire feed speed, arc control, etc. are all communicat-ed digitally via the control cable.

WARNING

Non Synergic CV:This type of CV mode behaves more like a conven-tional CV power source. Voltage and WFS are inde-pendent adjustments. Therefore to maintain the arccharacteristics, the operator must adjust the voltage tocompensate for any changes made to the WFS.

All CV Modes:Arc Control, often referred to as wave control, adjuststhe inductance of the wave shape. The wave controladjustment is similar to the "pinch" function in that it isinversely proportional to inductance. Therefore,increasing wave control greater than 0.0 results in aharsher, colder arc while decreasing the wave controlto less than 0.0 provides a softer, hotter arc.(See Figure B.2)

• ARC CONTROL

Also known as Inductance or Wave Control. Allowsoperator to vary the arc characteristics from "soft" to"harsh" in all weld modes. It is adjustable from -10.0 to+10.0, with a nominal setting of 00.0 (The nominal set-ting of 00.0 may be displayed as OFF on some PowerFeed® wire feeder control panels). See the WeldingMode descriptions, below, for detailed explanations ofhow the Arc Control affects each mode.

CONSTANT VOLTAGE WELDING

Synergic CV:For each wire feed speed, a corresponding voltage ispreprogrammed into the machine through special soft-ware at the factory. The nominal preprogrammed volt-age is the average voltage for a given wire feedspeed, but may be adjusted to preference. When thewire feed speed changes, the Power Wave® automati-cally adjusts the voltage level correspondingly tomaintain similar arc characteristics throughout theWFS range.

POWER WAVE® 355M

PULSE-ON-PULSE® (GMAW-PP)Pulse on Pulse® is a Lincoln process specificallydesigned for use in welding relatively thin, less than1/4"(6.4mm) thick aluminum (See Table B.3). It givesweld beads with very consistent uniform ripple.

In Pulse on Pulse® modes, two distinct pulse types areused, instead of the single pulse type normally used inGMAW-P. A number of high energy pulses are usedto obtain spray transfer and transfer metal across thearc. Such pulses are shown in Figure B.4. After anumber "N" of such pulses, depending on the wirefeed speed used, an identical number "N" of low ener-gy pulses are performed. These low energy pulses,shown in Figure B.4, do not transfer any filler metalacross the arc and help to cool the arc and keep theheat input low.

The Peak Current, Background Current, andFrequency are identical for the high energy and lowenergy pulses. In addition to cooling the weld down,the major effect of the low energy pulses is that theyform a weld ripple. Since they occur at very regulartime intervals, the weld bead obtained is very uniformwith a very consistent ripple pattern. In fact, the beadhas its best appearance if no oscillation of the weldinggun ("whipping") is used.(See Figure B.5)

When Arc Control is used in the Pulse on Pulse®

modes, it does the same things it does in the otherpulsed modes: decreasing the Arc Control decreasesthe droplet transfer and weld depos it ion rate.Increasing the Arc Control increases the droplet trans-fer and weld deposition rate. Since Arc Control variesweld droplet transfer rate, the Arc Control can be usedto vary the ripple spacing in the weld bead.

PULSE WELDING

Pulse welding procedures are set by controlling anoverall "arc length" variable. When pulse welding, thearc voltage is highly dependent upon the waveform.The peak current, back ground current, rise time, falltime and pulse frequency all affect the voltage. Theexact voltage for a given wire feed speed can only bepredicted when all the pulsing waveform parametersare known. Using a preset voltage becomes impracti-cal, and instead the arc length is set by adjusting"trim".

Trim adjusts the arc length and ranges from 0.50 to1.50, with a nominal value of 1.00. Trim values greaterthan 1.00 increase the arc length, while values lessthan 1.00 decrease the arc length.

All pulse welding programs are synergic. As the wirefeed speed is adjusted, the Power Wave® will auto-matically recalculate the waveform parameters tomaintain similar arc properties.

The Power Wave® utilizes "adaptive control" to com-pensate for changes in electrical stick out while weld-ing. (Contact to Work Distance is the distance fromthe contact tip to the work piece.) The Power Wave®

wave forms are optimized for a 0.75" (19mm) stick-out. The adaptive behavior supports a range of stick-outs from 0.50" (13mm) to 1.25" (32mm). At very lowor high wire feed speeds, the adaptive range may beless due to reaching physical limitations of the weldingprocess.

Arc Control, often referred to as wave control, in pulseprograms usually adjusts the focus or shape of thearc. Wave control values greater than 0.0 increase thepulse frequency while decreasing the background cur-rent, resulting in a tight, stiff arc best for high speedsheet metal welding. Wave control values less than0.0 decrease the pulse frequency while increasing thebackground current, for a soft arc good for out-of-posi-tion welding.

BENEFITS OF PULSE ON PULSE® FROMLINCOLN ELECTRIC

• Excellent appearance of the weld bead• Improved cleaning action• Reduced porosityTable B.2 shows WFS and Trim settings for commonaluminum types and wire sizes when welding withPulse-on-Pulse®. The welds made to obtain the valuesin the table were fillet welds in the flat position. Thevalues in the table can be helpful as a starting point toestablish a welding procedure. From there, adjust-ments need to be made to set the proper procedurefor each specific application (out-of-position, othertypes of joints, etc.).The comments on Table B.3 show values of WFSbelow which it is not recommended to weld. The rea-son is, that below these values the weld transfer willchange from a spray arc to a short-arc, which is notadvisable when welding aluminum.

TIG GTAWThe TIG mode features continuous control from 5 to425 amps. The TIG mode can be run in either theTouch Start TIG or Scratch start mode.

The Arc Control level selects the starting mode.

Between –10 and 0, the Touch Start TIG mode isselected. The OCV is controlled below 10V and theshort circuit "TIG touch" current is maintained atapproximately 25 amps, independent of the presetcurrent. When the tungsten is lifted, an arc is initiatedand the output is regulated at the preset value. A set-ting of 0, results in the most positive arc initiation. Asetting of -10 reduces hot start. Procedure to start theweld, and from there, to ramp to the welding procedure overa specified amount of time. Typically starting procedure on ahigher “+” setting is known as a “Hot Start”. Setting a start-ing procedure on a lower setting is known as a “Cold Start”.

Between 0 and 10, the Scratch starting TIG mode isselected. In this range, the OCV of the machine iscontrolled between 50 and 70 volts

WELDING PROCEDURES FOR PULSE-ON-PULSE® (TABLE B.2)

(See Figure B.3)SMAWIn SMAW (STICK mode), arc control adjusts the arcforce. It can be set to the lower range for a soft andless penetrating arc characteristic (negative numericvalues) or to the higher range (positive numeric val-ues) for a crisp and more penetrating arc. Normally,when welding with cellulosic types of electrodes(E6010, E7010, E6011), a higher energy arc isrequired to maintain arc stability. This is usually indi-cated when the electrode sticks to the work-piece orwhen the arc pops-out during manipulative technique.For low hydrogen types of electrodes (E7018, E8018,E9018, etc.) a softer arc is usually desirable and thelower end of the Arc Control suits these types of elec-trodes. In either case the arc control is available toincrease or decrease the energy level delivered to thearc.

ARC GOUGINGGouging is basically removing metal to form a bevel orgroove in a piece of steel with controlled forced airand a carbon rod.

The common procedures for Arc Gouging metal are:

• Removing poor welds from a weldment so that newwelds can be made.

• Creating a welding groove or grooves in two piecesof steel butted together. (See Example below)

Mode 9 in the POWER WAVE® 355M is specifically forgouging. Gouging can also be done in the stick softand crisp modes. Setting the output of the Stick Softmode to 425 amps will enable the arc-gouging mode.The actual output current will depend on the size ofcarbon used. The recommended maximum size car-bon is 5/16".

POWER MODE®

The Power Mode® process was developed by Lincolnto maintain a stable and smooth arc at low proceduresettings which are needed to weld thin metal withoutpop-outs or burning-through. For aluminum welding, itprovides excellent control and the ability to maintainconstant arc length. This results in improved weldingperformance in two primary types of applications.

• Short Arc MIG at low procedure settings.

• Aluminum MIG welding.

Power Mode® is a method of high speed regulation ofthe output power whenever an arc is established. Itprovides a fast response to changes in the arc. Thehigher the Power Mode® Setting, the longer the arc. Ifa welding procedure is not established, the best wayto determine the Power Mode® Setting is by experi-mentation until the desired output result is estab-lished.

In the Power Mode® two variables need to be set:

• Wire Feed Speed

• Power Mode® Trim

Setting up a Power Mode® procedure is similar to set-ting a CV MIG procedure. Select a shielding gasappropriate for a short arc process.

• For steel, use 75/25 Ar/CO2 shield gas.

• For stainless, select a Helium blend Tri-Mix.

• For aluminum, use 100% Ar.

Start by setting the wire feed speed based upon mate-rial thickness and appropriate travel speed. Thenadjust the Volts/Trim knob as follows:

• For steel, listen for the traditional “frying egg”sound of a good short-arc MIG procedure to knowyou have the process set correctly.

• For aluminum, simply adjust the Volts/Trim knobuntil the desired arc length is obtained.

Note the Volts/Trim display is simply a relative numberand DOES NOT correspond to voltage.

SAFETY PRECAUTIONS

CAPACITOR DISCHARGE PROCEDURE

1. Obtain a power resistor (25 ohms, 25 watts).

2. Hold resistor body with electrically insulated glove.DO NOT TOUCH TERMINALS. Connect the resis-tor terminals across the two studs in the positionshown. Hold in each position for 1 second. Repeatfor all four capacitors.

3. Use a DC voltmeter to check that voltage is notpresent across the terminals on all four capacitors.

ROUTINE MAINTENANCERoutine maintenance consists of periodically blowingout the machine, using a low pressure airstream, toremove accumulated dust and dirt from the intake andoutlet louvers, and the cool ing channels in themachine.

CAPACITORTERMINALS

RESISTOR

PERIODIC MAINTENANCECalibration of the POWER WAVE® 355M is critical toits operation. Generally speaking the calibration willnot need adjustment. However, neglected or improp-erly calibrated machines may not yield satisfactoryweld performance. To ensure optimal performance,the calibration of output Voltage and Current shouldbe checked yearly.

CALIBRATION SPECIFICATIONOutput Voltage and Current are calibrated at the fac-tory. Generally speaking the machine calibration willnot need adjustment. However, if the weld perfor-mance changes, or the yearly calibration checkreveals a prob lem, contact the Lincoln E lectricCompany for the calibration software utility.

The calibration procedure itself requires the use of agrid, and certified actual meters for voltage and cur-rent. The accuracy of the calibration will be directlyaffected by the accuracy of the measuring equipmentyou use. Detailed instructions are available with theutility.

ELECTRIC SHOCK can kill.• Do not touch electrically live parts or

electrode with skin or wet clothing.• Insulate yourself from work and

ground• Always wear dry insulating gloves.

------------------------------------------------------------------------EXPLODING PARTS can causeinjury.• Failed parts can explode or cause other

parts to explode when power is applied.

• Always wear a face shield and longsleeves when servicing.

POWER WAVE® 355M

USING THE STATUS LED TOTROUBLESHOOT SYSTEM PROBLEMS

The Power Wave® / Power Feed® are best diagnosedas a system. Each component (power source, userinterface, and feedhead) has a status light, and whena problem occurs it is important to note the conditionof each. In addition, errors displayed on the user inter-face in most cases indicate only that a problem existsin the power source, not what the problem may be.Therefore, prior to cycling power to the system,check the power source status light for errorsequences as noted below. This is especiallyimportant if the user interface displays "Err 006"or "Err 100" .

Included in this section is information about the powersource Status LED, and some basic troubleshootingcharts for both machine and weld performance.

The STATUS LIGHT is a two color light that indicatessystem errors. Normal operation is a steady greenlight. Error conditions are indicated in the followingchart.

NOTE: The POWER WAVE® 355M status light willflash green, and sometimes red and green, for up toone minute when the machine is first turned on. Thisis a normal situation as the machine goes through aself test at power up.

LIGHT CONDITIONStatus LED is solid green (no blinking).

Status LED is blinking green.

Status LED is blinking red and green.

Status LED is solid red (no blinking).

Status LED is blinking red.

MEANING1. System OK. Power source communicating normally

with wire feeder and its components, if other fea-tures and components show they are powered up.

2. Occurs during a reset, and indicates the POWERWAVE® 355M is mapping (identifying) each compo-nent in the system. Normal for first 1-10 secondsafter power is turned on, or if the system configura-tion is changed during operation.

3. Non-recoverable system fault. If the PS Status lightis flashing any combination of red and green, errorsare present in the POWER WAVE® 355M. Read theerror code before the machine is turned off.

Error Code interpretation through the Status light isdetailed in the Service Manual. Individual code digitsare flashed in red with a long pause between digits. Ifmore than one code is present, the codes will beseparated by a green light.

To clear the error, turn power source off, and backon to reset.

Non recoverable hardware fault. Generally indicatesnothing is connected to the POWER WAVE® 355Mwire feeder receptacle. See Trouble Shooting Section.

Not applicable.

Contact the Service Department for instructions on reloading theWelding Software.Contact the Service Department for instructions on reloading theWelding Software.Contact the Service Department for instructions on reloading theWelding Software.Excessive Primary current present. May be related to a short in themain transformer or output rectifier.Low voltage on the main capacitors. May be caused by improperinput configuration. When accompanied by an overvoltage error on the same side, itindicates no capacitor voltage present on that side, and is usuallythe result of an open or short in the primary side of the machine.Excess voltage on the main capacitors. May be caused by improp-er input configuration.

When accompanied by an under voltage error on the same side, itindicates no capacitor voltage present on that side, and is usuallythe result of an open or short in the primary side of the machine.

Indicates over temperature. Usually accompanied by Thermal LED.Check fan operation. Be sure process does not exceed duty cyclelimit of the machine.

Capacitor precharge failed. Usually accompanied by codes 32-35.The secondary (weld) current limit has been exceeded. When thisoccurs the machine output will phase back to 100 amps, typicallyresulting in a condition referred to as "noodle welding"

NOTE: The secondary limit is 570 amps for the standard stud, and325 amps for all single phase operation.

The maximum voltage difference between the main capacitors hasbeen exceeded. May be accompanied by errors 32-35.

Error codes that contain three or four digits are defined as fatalerrors. These codes generally indicate internal errors on theControl Board. If cycling the input power on the machine does notclear the error, try reloading the operating system. If this fails,replace the control board.
