• Insert the polarity selection plug in the park socket and lock in place by turning to the right.
• Insert the electrode holder plug and workpiece lead into the welding current socket depending on ap-
plication and lock in place by turning to the right. The corresponding polarity will be based on the in-
formation of the electrode manufacturer on the electrode packaging.
5.3.2 Welding task selection
• Select MMA JOB 128
> see 11.1 chapter
.
You can only change the JOB number when no welding current is flowing.

5.3.3 Arcforce
During the welding process, arcforce prevents the electrode sticking in the weld pool with increases in
current. This makes it easier to weld large-drop melting electrode types at low current strengths with a
short arc in particular.
