Pulse welding
Pulse welding means that the system switches between two currents periodically with a pulse current
(Ipuls), a pulse pause current (IPP), a balance (
) and a frequency (
) having been defined first.
Figure 4-47
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 =
x Tpuls, e.g. 30% x 1 s = 0.3 s
