Setting:
• Negative values: rutile electrode types
• Values at zero: basic electrode types
• Positive values: cellulose electrode types
5.5.2.3 Hotstart
The hotstart device improves the ignition of the stick electrodes using an increased ignition current.

Hotstart time
b) =
Hotstart current
I =
Welding current
t =
Time

5.5.2.4 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!
