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 electrode characteristics you can select at the machine control are guidíng values. Each
characteristics can be optimised according to electrode type and the related welding properties. -
