Arcforce; Antistick - EWM Tetrix 451 AC/DC AW FW Operating Instructions Manual

Design and function
Welding current polarity reversal (polarity reversal)
5.9.4

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

Figure 5-66
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.
