Starting Current <100% (Softstart); Anti-Stick Function - Fronius MagicWave 190 Operating Instructions Manual

Starting current A starting current < 100% (SoftStart) is intended for basic electrodes. Ignition takes place
< 100 % at a low welding current. Once the arc is stable, the welding current continues to rise until
(SoftStart) it reaches the welding current command value.

Example with a starting current < 100% (SoftStart)
Anti-stick func- As the arc becomes shorter, the welding voltage may drop so far that the rod electrode will
tion tend to stick. This may also cause the rod electrode to burn out.
Electrode burn-out is prevented by activating the anti-stick function. If the rod electrode be-
gins to stick, the power source immediately switches the welding current off. After the rod
electrode has been detached from the workpiece, the welding process can be continued
without any problems.
The anti-stick function can be activated and deactivated in the rod electrodes menu.

Benefits:
- Improved ignition properties for elec-
trodes that ignite at low welding cur-
rents
- Largely prevents slag inclusions
- Reduces welding spatter
