SoftStart function

The SoftStart function is intended for basic electrodes. Ignition takes place at a low weld-
ing current. Once the arc is stable, the welding current continues to rise until it reaches
the welding current command value.

Press the Parameter selection button to select the parameter you wish to correct
Use the adjusting dial to set the selected parameter to the desired value. The para-
meter value is displayed in the digital display located above it.
Improved ignition, even when using electrodes with poor ignition properties
Better fusion of the base material during start-up phase, meaning fewer cold-shut
defects
Largely prevents slag inclusions

Function:
during the specified hot-current time (Hti),
the welding current is increased to a cer-
tain value. This value (HCU) is higher than
the selected welding current (I

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