1. MMa
Select MMA welding by pressing the selection button of MMA welding. The led is lit when
MMA is on.
2. arc force
Press the arc force button and you will see the numerical value corresponding to the MMA
dynamics in the display. Factory setting for all electrode types is zero. You can change the
value by turning the pulse potentiometer. If numerical value is adjusted negative (-1...9) the
arc is softened, and the amount of spatter decreases when welding at the upper end of the
recommended current range of the electrode. On the positive side (1...9) the arc is rough.
In TIG mode, you can select the max. and min. current for the foot pedal (PEDAL LO/HI).
