6.2 Pulse width mode
In this operating mode, the PSU inverts the heat scale value predetermined by the
timer into the corresponding pulse width.
The welding current is not controlled!
In this case, the welding current is determined by the resistances in the secondary
circuit. Due to the small dimensions and the low overall weight of the welding trans-
former, the transformer can be installed close to the electrode guns in order to keep
the resistance of the secondary circuit as low as possible. The following relations
apply:
00 SKT (scale values) minimum pulse width (approx. 80
m
s)
99 SKT (scale values) maximum pulse width (approx. 450
m
s)
