Pulse Welding - EWM T 4.00 - AC/DC Comfort 2.0 Operating Instruction

4.2.6

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 (
AMP = main current, e.g. 100 A
Ipuls = pulse current =
IPP = pulse pause current = 1–200% of AMP
Tpuls = duration of one pulse cycle = 1/
= balance =
