5.7.2.1
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.
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.
The electrode types used must be selected on the machine control to achieve the optimum
welding properties of the electrode types.
