5.2.5 Pulse welding
Pulse welding means that the system switches between two currents periodically with a pulse current (I-
puls), a pulse pause current (IPP), a balance (
) and a frequency (
) having been defined first.
Figure 5-38
AMP = main current, e.g. 100 A
Ipuls = pulse current =
x AMP, e.g. 140% x 100 A = 140 A
IPP = pulse pause current = 1–200% of AMP
Tpuls = duration of one pulse cycle = 1/
, e.g. 1/100 Hz = 10 ms
= Balance

With manual average value pulsing, all parameters can be set independently of each other, especially the
pulse pause current IPP =
. This means that the average value of the preset main current can alter.
The machine function is enabled in the machine configuration menu. The parameter
must be set to
