Hotstart
The hotstart device improves the ignition of the stick electrodes using an increased ignition current.

Action Result
Hotstart current
Increased ignition current during the set hotstart period to optimise the
arc ignition. Setting from 20 A to 350 A.
Hotstart period
Increased ignition current (hotstart current) flows during the period set.
Setting from 0 s to 2 s.
5.6.3
Arcforce correction (welding characteristics)
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.
Operating
element
Action Result
Arcforce
To adjust the welding parameters to the electrode type used. Infinite
setting from rutile (soft arc) to cellulose (hard arc) electrode types.
Low arcforcing = soft arc,
low increase in current before the short-circuit.
Use with rutile coated stick electrodes.
Moderate arcforcing = normal arc,
moderate increase in current before the short-circuit.
Use with basic coated stick electrodes.
Strong arcforcing = hard arc,
strong increase in current before the short-circuit.
Use with cellulose stick electrodes.
5.6.4
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!

The remote controls are operated on the 14-pole remote control connection socket.
