Antistick
If the stick electrode sticks despite the arcforcing device, the machine automatically switches over
to the minimum current within about 1 second to prevent the electrode overheating. If the antistick
device has been triggered, check the welding current setting and correct if necessary.

•
Strike the stick electrode on the workpiece.
•
The stick electrode ignites the arc at the set hotstart current I
Hot
and welds with this current until
the hotstart time t
Hot
elapses.
•
The hotstart current drops to the set main current I
1
and remains constant until the end of the
welding process (see flow chart)
•
If the stick electrode sticks in the welding pool for longer than 1 second, the antistick device comes
into force and the welding current is reduced to the minimum current. Check the welding current
setting and correct as necessary according to the manufacturer's instructions.
