Factory setting -
To obtain optimum welding results, it will sometimes be necessary to adjust the arc-
force dynamic.

0 soft, low-spatter arc
100 harder, more stable arc
Functional principle:
at the instant of droplet transfer or in the event of a short circuit, there is a momentary
rise in amperage. In order to obtain a stable arc, the welding current is temporarily
increased. If the rod electrode threatens to sink into the weld pool, this measure pre-
vents the weld pool solidifying, as well as preventing more prolonged short circuiting of
the arc. This largely prevents the rod electrode from sticking.
