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.
Down slope setting (0 to 10 sec)
Time needed to shift from welding current to minimum current. Avoids cracks and craters at the end of
welding.
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
protects 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.
n.b. : You can check your settings at any time by pressing the parameter button, without turning the wheel.
