Antistick
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!

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 5-17
AMP = Main current; e.g. 100 A
IPL = Pulse current = IP1 x AMP; e.g. 170% x 100 A = 170 A
IPP = Pulse pause current
Tpuls = Duration of one pulse cycle = 1/FrE; e.g. 1/1 Hz = 1 s
bAL = Balance = bAL x Tpuls; e.g. 30% x 1 s = 0.3 s
