Welding current polarity reversal (polarity reversal)

This function can be used to reverse the welding current polarity electronically.
For example, when welding with different electrode types for which different polarities are stipulated by
the manufacturer, the welding current polarity can be switched easily on the control.
Not available for machines with voltage reduction device (VRD).

The Antistick feature prevents the electrode from annealing.
Should the electrode stick, 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.
