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.

Average value pulse welding
Average value pulse welding means that two currents are switched periodically, a current average value
(AMP), a pulse current (Ipuls), a balance (
) and a frequency (
) having been defined first. The
predefined ampere current average value is decisive, the pulse current (Ipuls) is defined by the
parameter as a percentage of the current average value (AMP). The pulse pause current (IPP) requires
no setting. This value is calculated by the machine control, so that the welding current average value
(AMP) is maintained at all times.
Figure 5-11
AMP = Main current; e.g. 100 A
Ipuls = Pulse current =
x AMP; e.g. 140% x 100 A = 140 A
IPP = Pulse pause current
Tpuls = Duration of one pulse cycle = 1/
; e.g. 1/1 Hz = 1 s
= Balance
