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).

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