5.3.2 Welding task selection
The following welding task selection is an example of use. In general, the selection process always has
the same sequence. Signal lights (LED) will show the selected combination.

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.

5.3.4 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).
