Antistick
Anti-stick prevents the electrode from annealing.
If the electrode sticks in spite of the Arcforce device, the machine
automatically switches over to the minimum current within about 1
second to prevent the electrode from overheating. Check the welding
current setting and correct according to the welding task!
