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 (
predefined ampere current average value is decisive, the pulse current (Ipuls) is defined by the
rameter 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.
AMP = Main current; e.g. 100 A
Ipuls = Pulse current =
IPP = Pulse pause current
