5.2.7 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
para-
meter 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 5-15
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
