decreasing the Inductance to less than 0.0 provides a

softer arc (less spatter).

Adjust range: from -10 to +10.

Factory default, Pinch is OFF.

The 2-Step - 4-Step changes the function of the

gun’s trigger.

2 Step trigger operation turns welding on and off

in direct response to the trigger. Welding process

is performed when the gun’s trigger is pulled.

4-Step mode allows to continue welding, when the

gun’s trigger is released. To stop welding, the

gun’s trigger is pulled again. 4-step mode

facilitates to making long welds.

Note: 4-Step does not work during Spot Welding.

Run-in WFS – sets the wire feed speed from the time

the trigger is pulled until an arc is established.

Factory default, Run-in is turned off.

Adjust range: from minimum to 3,81 m/min (150

in/min ).

Burnback Time – is the amount of time that the weld

output continues after the wire stops feeding. It

prevents the wire from sticking in the puddle and

prepares the end of the wire for the next arc start.

Factory default, Burnback Time is set at AUTO.

Adjust range: from 0 (OFF) to 0,25 seconds.
