5.5.2.2
Hotstart current and Hotstart time
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.

NOTE
A hot start is carried out without pulsing, and the pulse sequence begins with one pulse
after the hot start.
5.5.2.3
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!
