5.3.6 Pulse welding
5.3.7 Average value pulse welding
With average value pulsing, two currents are periodically toggled. The user can adjust the welding current
(average current value AMP), pulse current Ipuls (parameter
), balance
and frequency
to the
welding task. The pulse pause current (IPP) is calculated by the machine control, so that the welding cur-
rent average value (AMP) is maintained and shown. This makes this method especially suitable for
welding according to welding procedure specifications.
Figure 5-32
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

5.3.7.1 Average value pulsing, manual
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
