The maximum HotStart current is limited as follows:
-
Ignis 150 to 160 A
-
Ignis 180 to 200 A
Examples (set welding current = 100 A):
100 % = 100 A starting current = function deactivated
80 % = 80 A starting current = SoftStart
135 % = 135 A starting current = HotStart
200 % = 160 A starting current on Ignis 150 = HotStart, maximum current
limit is reached!
200 % = 200 A starting current on Ignis 180 = HotStart

Example of HotStart function
Features of SoftStart function:
-
Reduced pore formation with cer-
tain electrode types
Features of HotStart function:
-
Improved ignition properties, even
when using electrodes with poor
ignition properties
-
Better fusion of the base material
during the start-up phase, meaning
fewer cold-shut defects
-
Largely prevents slag inclusions
Arc-force dy-
namic
To obtain optimum welding results, it will sometimes be necessary to adjust the
arc-force dynamic.
Setting range: 0 - 100 (corresponds to 0 - 200 A current increase)
Operating principle:
At the moment of droplet transfer or in the event of a short circuit, the amper-
age is briefly increased in order to obtain a stable arc.
If the rod electrode is at risk of sinking into the weld pool, this measure prevents
the weld pool from solidifying, as well as preventing a prolonged short-circuit of
the arc. This largely prevents the rod electrode from sticking.
