Welding current setting
The value of the welding current needed depends on the thickness and the type of metal, as well as on the
welding configuration.
Advice : Take 30A/mm as a default setting for DC or 40A/mm for AC and adjust according to the piece to
weld.
Pulse frequency setting (from 0.2 to 20Hz)
The pulse frequency is the number of cycles (½ cycle of hot current, ½ cycle of cold current) made in
a second.
Cold current setting (low intensity) (from 20 to 70% of hot current)
Selected as a percentage of hot current : the colder the current, the cooler the welding piece will stay
during the welding process.
Post-gas setting (3 to 20 sec)
Time needed to shift from welding current to minimum current. Avoids cracks and craters at the end of wel-
ding.
Post-gas setting (3 to 20 sec)
This parameter determines the length of time in which gas is released after the arc has stopped. It pro-
tects the weld pool and the electrode against oxidization whilst the metal is cooling after welding.
Advice : Increase the time if the welding appears dark.
(For default setting : 25A=4sec. – 50A=8sec. – 75A=9sec. – 100A=10sec. – 125A=11sec. – 150A=13sec. - 200A=15sec).
Nb. : You can check your settings at any time by pressing the parameter button, without turning the
wheel.
