MMA WELDING

The heat generated by an ELECTRIC ARC between a coated ELECTRODE and the PIECE TO BE WELDED makes these two elements melt. The protection of the melted material is

assured by the coating of the electrode which evaporates thus creating a protective atmosphere.

The coating part which melts becomes protective slag for the weld pool and is to be removed later on.

MMA ELECTRODE WELDING

AC/DC CURRENTS AND WELDING: DIFFERENCES

In a direct current welding machine the output current remains the same in the time

In an alternate current welding machine, the output current varies in the time (sinusoidal wave)

RUTILE, BASIC, CELLULOSIC ELECTRODES

- Welding in all positions- Pipes or whenever a return from the back is possible

- DC power sources with high no-load voltage are necessary- Irregolar seam- High hidrogen generation

- High penetration- Good workability- Reduced slag

Cellulosic

- Welding in all positions, evenat high thickness- High deposit rates- High mechanical quality welds, even with material containigimpurities

- Difficult strike- Low stability arc- DC power source- Difficult storage

- VISCOUS pool: allows for a good weldin any position- Excellent material purifier-Very low hidrogengeneration

Basic

- Horrizontal, vertical and filletwelding for low thickness-Welds with good appearancebut only passable mechanicalproperties(good strength butrisk of cracks )

- Fluid pool- Poor cleaning effect- High hydrogen generation

- Easy strike- Stable arc- Easy storage- AC and DC power source- Low cost

DUTY CYCLE: WHAT IS IT ?

STOP

0 6 10

100A @ 60%

Min.

Duty cycle is the number ofminutes, within a 10-minute period,

during which, at ambient temperature of 40°C, a welding

machine can operate without the interruption of the thermal

protection

You can weld at a current of 100A for 6 minutes, then, the welder needs a rest period

of 4 minutes.

100A @ 60%OPERATIVE STOP

DUTY CYCLE

The cold start of the welding machine, at the beginning, allows for a higher duty cycle at the max. current - the correct functioning is safeguarded

On the run, the performances stabilize to the values declared on the data sheet

CURRENTS & DUTY CYCLE: NORMS

1° Maximum current @ Duty cycle

2° Current @ 60%

3° Current @ 100%

Norm EN 60974-1

(continuous welding for the welder)

(continuous welding for robotized systems)

The underlined parameters are fix

According to the international norms 3 different values of current are to be declared for each Duty Cycle at ambient temperature of 40°C:

Telwin declares all the duty cyclesat ambient temperature of 40°C

A Tamb = 25°C I max = 130A@35%

A Tamb = 40°C I max = 130A@25%

The Duty Cycle relative to the maximum current DEPENDS on the ambient temperature in which it is measured.At the same current, a lower ambient temperature corresponds to a higherDuty Cycle

Hot start Device to facilitate the striking of the electric arc by supplying over-current at each restart of the welding.

Anti stick Device to turn automatically off the welding generator when the electrode sticks to the material being welded, and to enable its manual removal.

compressed air onto the same bath, thus providing the removal ofthe melted material.
