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.

Hotstart

The function hot start ensures a secure igniting of the arc and a sufficient heating to the still cold parent
metal at the beginning of the welding process. The ignition takes place here with increased current (hot
start current) over a certain time (hot start time).
