Functional characteristics

TIG welding

Functional sequence of hotstart device
The hotstart device uses an increased ignition current to improve arc ignition. The parameters for
the hotstart current and time can be adjusted individually.
When the stick electrode has been struck, the arc ignites at the adjusted hotstart current AMP (factory
setting: 120% of main current) and welds at this current until the hotstart time in seconds has elapsed
(factory setting: 1 second). The hotstart current then reduces to the main current set.

Main current setting
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!
