Press until the hotstart time signal light sec comes
on.
Set hotstart time.
5.14.7 Arcforce
During the welding process, arcforce prevents the electrode sticking in the weld pool with increases in
current. This makes it easier to weld large-drop melting electrode types at low current strengths with a
short arc in particular.

Select arcforcing welding parameter.
The signal light comes on in red.
Set arcforcing.
-40 = rutile electrode types
0 = basic electrode types
+40 = cellulose electrode types
5.14.8 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!
