Turn the adjusting dial until the desired value is reached

NOTE!
The maximum HotStart current is limited to 180 A.
Examples:
(set welding current = 100 A)
- 100% Starting current = 100 A Function deactivated
- 80% Starting current = 80 A SoftStart
- 135% Starting current = 135 A HotStart
- 200% Starting current = 180 A HotStart (maximum current limit reached!)
Example of HotStart function
Features of SoftStart function:
- Reduced pore formation with certain
electrode types
Features of HotStart function:
- Improved ignition properties, even
when using electrodes with poor igniti -
on properties
- Better fusion of the base material du -
ring the start-up phase, meaning fewer
cold-shut defects
- Largely prevents slag inclusions
Arc-force dynam -
ic
To obtain optimum welding results, it will sometimes be necessary to adjust the arc-force
dynamic.
Setting range: 0 - 100 (corresponds to 0 - 200 A current increase)
Operating principle:
At the moment of droplet transfer or in the event of a short circuit, the amperage is briefly
increased in order to obtain a stable arc.
If the rod electrode threatens to sink into the weld pool, this measure prevents the weld
pool solidifying, as well as preventing a prolonged short-circuit of the arc. This largely pre -
vents the rod electrode from sticking.
Setting the arc-force dynamic:
Press the setting value button until
the arc-force dynamic indicator lights up
Turn the adjusting dial until the desired correction value is reached
