WARNING
Mar 95
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.

iiSAFETYii
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 can kill.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-freegloves 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.
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 below Threshold Limit Values (TLV)using local exhaust or mechanical ventilation. Inconfined spaces or in some circumstances, outdoors, arespirator may be required. Additional precautions arealso required when welding on galvanized steel.
5.b. 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 products.
5.c. 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.d. Read and understand the manufacturers instructions for thisequipment and the consumables to be used, including thematerial safety data sheet (MSDS) and follow youremployers safety practices. MSDS forms are available fromyour welding distributor or from the manufacturer.

Mar 95
WELDING SPARKS 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 hot
materials 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 contact cancause 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 circuits.This can create fire hazards or overheat lifting chains orcables until they fail.

OC PRCAUTIONS DE SRET
Pour votre propre protection lire et observer toutes les instructionset les prcautions de sret specifiques qui parraissent dans cemanuel aussi bien que les prcautions de sret gnrales suiv-antes:
Sret Pour Soudage A LArc1. Protegez-vous contre la secousse lectrique:
a. Les circuits llectrode et la pice sont sous tensionquand la machine souder est en marche. Eviter toujourstout contact entre les parties sous tension et la peau nueou les vtements mouills. Porter des gants secs et sanstrous pour isoler les mains.
b. Faire trs attention de bien sisoler de la masse quand onsoude dans des endroits humides, ou sur un plancher met-allique ou des grilles metalliques, principalement dans les positions assis ou couch pour lesquelles une grandepartie du corps peut tre en contact avec la masse.
c. Maintenir le porte-lectrode, la pince de masse, le cble desoudage et la machine souder en bon et sr tat defonc-tionnement.
d.Ne jamais plonger le porte-lectrode dans leau pour lerefroidir.
e. Ne jamais toucher simultanment les parties sous tensiondes porte-lectrodes connects deux machines souderparce que la tension entre les deux pinces peut tre le totalde la tension vide des deux machines.
f. Si on utilise la machine souder comme une source decourant pour soudage semi-automatique, ces precautionspour le porte-lectrode sapplicuent aussi au pistolet desoudage.
2. Dans le cas de travail au dessus du niveau du sol, se protgercontre les chutes dans le cas ou on recoit un choc. Ne jamaisenrouler le cble-lectrode autour de nimporte quelle partie ducorps.
3. Un coup darc peut tre plus svre quun coup de soliel, donc:
a. Utiliser un bon masque avec un verre filtrant appropri ainsiquun verre blanc afin de se protger les yeux du rayon-nement de larc et des projections quand on soude ouquand on regarde larc.
b. Porter des vtements convenables afin de protger la peaude soudeur et des aides contre le rayonnement de larc.
c. Protger lautre personnel travaillant proximit ausoudage laide dcrans appropris et non-inflammables.
4. Des gouttes de laitier en fusion sont mises de larc desoudage. Se protger avec des vtements de protection libresde lhuile, tels que les gants en cuir, chemise paisse, pan-talons sans revers, et chaussures montantes.
5. Toujours porter des lunettes de scurit dans la zone desoudage. Utiliser des lunettes avec crans lateraux dans leszones o lon pique le laitier.
6. Eloigner les matriaux inflammables ou les recouvrir afin deprvenir tout risque dincendie d aux tincelles.
7. Quand on ne soude pas, poser la pince une endroit isol dela masse. Un court-circuit accidental peut provoquer unchauffement et un risque dincendie.
8. Sassurer que la masse est connecte le plus prs possible dela zone de travail quil est pratique de le faire. Si on place lamasse sur la charpente de la construction ou dautres endroitsloigns de la zone de travail, on augmente le risque de voirpasser le courant de soudage par les chaines de levage,cbles de grue, ou autres circuits. Cela peut provoquer desrisques dincendie ou dechauffement des chaines et descbles jusqu ce quils se rompent.
9. Assurer une ventilation suffisante dans la zone de soudage.Ceci est particulirement important pour le soudage de tlesgalvanises plombes, ou cadmies ou tout autre mtal quiproduit des fumes toxiques.
10. Ne pas souder en prsence de vapeurs de chlore provenantdoprations de dgraissage, nettoyage ou pistolage. Lachaleur ou les rayons de larc peuvent ragir avec les vapeursdu solvant pour produire du phosgne (gas fortement toxique)ou autres produits irritants.
11. Pour obtenir de plus amples renseignements sur la sret, voirle code Code for safety in welding and cutting CSA StandardW 117.2-1974.
PRCAUTIONS DE SRET POURLES MACHINES SOUDER TRANSFORMATEUR ET REDRESSEUR
1. Relier la terre le chassis du poste conformement au code dellectricit et aux recommendations du fabricant. Le dispositifde montage ou la piece souder doit tre branch unebonne mise la terre.
2. Autant que possible, Iinstallation et lentretien du poste seronteffectus par un lectricien qualifi.
3. Avant de faires des travaux linterieur de poste, la debranch-er linterrupteur la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sret leur place.

WARNING
SAFETY PRECAUTIONS
SELECT SUITABLE LOCATION
The Invertec V350-PRO will operate in harsh environ-ments. Even so, it is important that simple preventativemeasures are followed in order to assure long life andreliable operation.
The machine must be located where there is free cir-culation of clean air such that air movement in theback, out the sides and bottom will not be restricted.
Dirt and dust that can be drawn into the machineshould be kept to a minimum. Failure to observethese precautions can result in excessive operatingtemperatures and nuisance shutdown.
Keep machine dry. Shelter from rain and snow. Donot place on wet ground or in puddles.
DO NOT MOUNT OVER COMBUSTIBLE SURFACES.
Where there is a combustible surface directly understationary or fixed electrical equipment, that surfaceshall be covered with a steel plate at least .06(1.6mm)thick, which shall extend not less than 5.90(150mm)beyond the equipment on all sides.
STACKINGV350-PRO cannot be stacked.
TILTINGPlace the machine directly on a secure, level surfaceor on a recommended undercarriage. The machinemay topple over if this procedure is not followed.
INPUT AND GROUNDING CONNECTIONS Only a qualified electrician should connect the
Invertec V350-PRO. Installation should be made inaccordance with the appropriate National ElectricalCode, all local codes and the information detailedbelow.
When received directly from the factory, multiple volt-age machines are internally connected for 460VAC.If 460VAC is the desired input, then the machine maybe connected to the power system without any setuprequired inside the machine.
CAUTION
Initial 200VAC - 415VAC and 575VAC operation willrequire an Input voltage panel setup.
Open the access panel on the rear of the machine. For 200 or 230: Position the large switch to 200-
230.For higher voltages: Position the large switch to380-575.
Move the "A" lead to the appropriate terminal.

OC PARALLEL OPERATION
The V350-Pro can be paralleled in CC mode. For bestresults, the currents of each machine should be rea-sonably well shared. As an example, with twomachines set up in parallel for a 400 amp procedure,each machine should be set to deliver approximately200 amps, not 300 amps from one and 100 amps fromthe other. This will minimize nuisance shutdown con-ditions. In general, more than two machines in paral-lel will not be effective due to the voltage requirementsof procedures in that power range.
To set machine outputs, start with output control potsand arc control pots in identical positions. Use theoutput control pots to balance the currents and main-tain the desired current. The arc control pots shouldbe kept identical on the two machines.

WARNING
SAFETY PRECAUTIONS
GENERAL DESCRIPTION
The Invertec V350-Pro offers multi-process CV, CC,and DC welding and is rated 350 amps, 34 volts at a60% duty cycle. The V350-Pro is available in either aConstruction version (no wire feeder connection andauxiliary power) and a Factory & Advanced Processversions (includes wire feeder connection and relatedpower). The factory model is the construction model with
the addition of the Wire Feeder/Remote Adapter.
In this form, the V350-Pro provides the hardware topower and connect to 24, 42 or 115 VAC wire feeders.
The advanced process model is the factory modelwith an advanced process panel installed in place ofthe standard mode panel. In this form, the V350-Proprovides access to the 5 standard weld modes (StickSoft, Stick Crisp, TIG, CV-Wire, CV-Innershield),gouge, constant power and pulse MIG weld modes.
DUTY CYCLE
The V350-Pro is rated at 350 amps, 60% duty cycle(based on a 10 minute cycle). It is also rated at 300amps, 100% duty cycle.
OPERATIONAL FEATURES and CONTROLS:
UPPER CONTROL PANEL1. AMPS Meter Prior to STICK or TIG operation (current flow), the
meter displays preset current value (+/- 2 amps or+/- 3%, whichever is greater).
Prior to CV operation, the meter displays four dash-es indicating non-presettable AMPS.
During welding, this meter displays actual averageamps.
After welding, the meter holds the actual currentvalue for 5 seconds. Output adjustment while in the"hold" period results in the "prior to operation" char-acteristics stated above. The displays blink indicat-ing that the machine is in the "Hold" period.
2. VOLT METER Prior to CV operation (current flow), the meter dis-
plays desired preset voltage value (+/- .5V). Prior to STICK or TIG operation, the meter displays
the Open Circuit Voltage of the Power Source or fourdashes if the output has not been turned on.
During welding, this meter displays actual averagevolts.
After welding, the meter holds the actual voltagevalue for 5 seconds. The displays blink indicatingthat the machine is in the "Hold" period.
Output adjustment while in the "hold" period resultsin the "prior to operation" characteristics statedabove.
3. OUTPUT CONTROL Output control is conducted via a single turn poten-
tiometer. Adjustment is indicated by the meters as stated
above. When in TIG modes, this control sets the maximum
welding current. Full depression of a foot or handAmptrol results in the preset level of current.
4. WELD TERMINALS-REMOTE / ON Two status lights indicate the location of trigger con-
trol as determined by the "WELD TERMINALS" pushbutton.
If trigger control is local "weld terminals on", the ONdisplay will be lit.
If trigger control is remote "weld terminals remotelycontrolled", the REMOTE display will be lit.

OC The unit will power up in "pre-determined preferred"
trigger modes.
STICK = ON CV = REMOTETIG = REMOTE if remote output controls are attachedto the machine.TIG = 0N if remote output controls are not attached tothe machine.For all versions, these trigger modes can be over-ridden(switched) with the WELD TERMINALS push button. Whenchanged, the unit will power up in the configuration it was inwhen it was last powered down.
5. THERMAL This status light indicates when the power source has been
driven into thermal overload. If the output terminals were"ON", the "ON" light will blink indicating that the output willbe turned back on once the unit cools down to an accept-able temperature level. If the unit was operating in the"REMOTE" mode, the trigger will need to be openedbefore or after the thermal has cleared and closed after themachine has cooled down to an acceptable temperature toestablish output.
6. CONTROL-REMOTE / LOCAL Two status lights indicate the location of output control as
pre-determined by the power sources auto-configure sys-tem.
The LOCAL display will be lit when control is at the powersource.
The REMOTE display will be lit when a remote pot/controlis detected.
These Output Control configurations can be overridden(switched) with the CONTROL push button. When changed,the unit will power up in the configuration it was in when itwas last powered down.
7. WELD MODE SELECT - FACTORY AND CONSTRUCTION (See Figure B.1)
The Mode Control button selects from the followingwelding modes.
CC-STICK SOFT: The Stick Soft process features con-tinuous control ranging from 5 to 425 amps. This modewas intended for most SMAW applications, and ArcGouging.
Arc Gouging: Setting the output of the Stick Softmode to 425 amps will enable the arc-gougingmode. The actual output current will depend on thesize of carbon used. The recommended maximumsize carbon is 5/16".
The Hot Start control regulates the starting currentat arc initiation. Hot Start can be adjusted from min-imum (0), with no additional current added at arcstart, to maximum (10), with double the preset cur-rent or 425 amps (max of machine) added for thefirst second after arc initiation.
The Arc Control regulates the Arc Force to adjustthe short circuit current. The minimum setting (-10)will produce a "soft" arc and will produce minimalspatter. The maximum setting (+10) will produce a"crisp" arc and will minimize electrode sticking.
CC-STICK CRISP:The Stick Crisp mode features con-tinuous control from 5 to 425 amps. This mode wasintended primarily for pipe welding applications.
The Hot Start control regulates the starting current atarc initiation. Hot Start can adjust starting current upor down by 25% of the preset value. The recom-mended setting for Hot Start is 5 where the initial cur-rent is equal to the preset current.

OC The Arc Control regulates the Arc Force to adjust the
short circuit current. The minimum setting (-10) willproduce a "soft" arc and will produce minimal spat-ter. The maximum setting (+10) will produce a "crisp"arc and will minimize electrode sticking.
TIG GTAW: The TIG mode features continuous controlfrom 5 to 425 amps. The TIG mode can be run in eitherthe TIG touch start or high frequency (optional equip-ment required) assisted start mode.
The Hot Start control selects the starting modedesired. A setting of less than 5, the TIG lift startmode is selected. The OCV is controlled below 10vand the short circuit "TIG touch" current is main-tained at 25 amps independent of the preset current.When the tungsten is lifted, an arc is initiated andthe output is regulated at the preset value. Hot startsettings between 0 and 5 regulate the arc initiationcurrent. A setting of 5 results in the most positive arcinitiation. A setting of 0 reduces hot start.
Hot Start settings between 5 and 10, select high fre-quency assisted starting TIG mode. In this range,the OCV of the machine is controlled between 50and 70 volts. If using the Lincoln K930-1 TIGModule, set the Hot start to 10 for maximum OCV.
The Arc Control is not used in the TIG mode.
TIG SOLENOID OPTION
The Solenoid only operates when the V350 is in theTIG mode. If the Weld Terminals are in Remote thenthe solenoid will open when the arc start switch isclosed. The solenoid will close after the arc switch hasbeen opened and the post flow time expired.
If the Weld Terminals are turned ON, then the sole-noid will open when the electrode is touched to thework. The electrode needs to remain in contact withthe work to allow for gas coverage before attempting tostart the arc. The solenoid will close after the arc hasbeen broken and the post flow time expired.
CV-WIRE: The CV-WIRE mode features continuouscontrol from 10 to 40 volts. The mode was intended formost GMAW, FCAW, and MCAW applications.
The Hot Start control is not used in the CV-WIREmode.
The Arc Control regulates pinch effect. At the mini-mum setting (-10), minimizes pinch and results in asoft arc. Low pinch settings are preferable for weld-ing with gas mixes containing mostly inert gases. Atthe maximum setting (+10), maximizes pinch effectand results in a crisp arc. High pinch settings arepreferable for welding FCAW and GMAW with CO2.
CV-INNERSHEILD: The CV-INNERSHEILD modefeatures continuous control from 10 to 45 volts. Thismode was designed for self-shielded flux cored wiresthat require tight voltage control.
The Hot Start control is not active in the CV-FLUXCORED mode.
The Arc Control regulates pinch effect. At the mini-mum setting (-10), minimizes pinch and results in asoft arc. At the maximum setting (+10), maximizespinch effect and results in a crisp arc. Most self-shielded wires work well at an Arc Control setting of 5.
