Setting:
• Negative values: rutile electrode types
• Values at zero: basic electrode types
• Positive values: cellulose electrode types

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).
For parameter setting,

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
second. This prevents the electrode from annealing. Check the welding
current setting and correct for the welding task in hand.
