Starting current
> 100% (HotStart)
Advantages
- Improved ignition properties, even when using electrodes with poor ignition properties
- Better fusion of parent material in the start phase, therefore less neutralization
- Slag inclusions largely avoided

Operation
During the set hot current time (Hti) the welding current I

rises to the HotStart current
HCU.
The setting of the available parameters is described in the "Setup Menu" section on page
76.
Starting current
< 100%
(SoftStart)
A starting current of < 100% (SoftStart) is suitable for basic electrodes. Ignition is carried
out with a low welding current. As soon as the arc is stable, the welding current continues
to increase until it reaches the welding current command value that was set.
Example of a starting current < 100% (SoftStart)
Advantages:
- Improvement of ignition properties with
electrodes that ignite at a low welding
current
- Slag inclusions largely avoided
- Reduction of welding spatter
