Arcforce; Antistick; Welding Current Polarity Reversal (Polarity Reversal) - EWM T 4.00 - AC/DC Comfort 2.0 Operating Instruction

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

4.2.5

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.

Anti-stick prevents the electrode from annealing.
If the electrode sticks in spite of the Arcforce device, the machine
automatically switches over to the minimum current within about 1
second to prevent the electrode from overheating. Check the welding
current setting and correct according to the welding task!
