Arcforce (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.
NOTE
The selectable electrode characteristics on the machine control are guideline values.
Every characteristic can also be optimised for the relevant electrode types and their
welding properties (see chapter "Arcforce correction").
The electrode types used must be selected on the machine control to achieve the optimum
welding properties of the electrode types.
