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).

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.

Antistick
The Antistick feature prevents the electrode from annealing.
Should the electrode stick despite the Arcforce feature, the machine
automatically switches to the minimum current within approx. one se-
cond. This prevents the electrode from annealing. Check the welding
current setting and correct for the welding task in hand.
