5.2.6 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
pa-
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.
Figure 5-18
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
The pulse pause current (IPP) requires no setting. This value is calculated by the machine control,
so that the welding current average value always corresponds to the main current selected.

5.2.6.1 Average value pulsing in the vertical-up position (PF)
This pulse variant was developed for welding in the PF position. Where necessary, the user can adjust
the preset welding parameters:
Parameter
is used for pulse current correction
Parameter
is used for frequency correction
Parameter
is used for balance correction
