Incorrect welding process selected
Select "MMA welding" or "MMA welding with Cel electrode" process
Starting current too low; electrode sticking during ignition
Increase starting current using HotStart function
Starting current too high; electrode consumed too quickly during ignition or is
generating a lot of spatter
Reduce starting current using SoftStart function
Electrode (e.g. grooved electrode) voltage too high
If possible, use alternative electrode or a power source with more welding
power
Comfort Stop Sensitivity (CSS) setting is too sensitive
Increase or deactivate the CSS value in the Setup menu
Break voltage (Uco) set too low
Increase break voltage (Uco) in Setup menu
Value of arc-force dynamic parameter (MMA welding) set too low
Increase value of arc-force dynamic parameter
Incorrect electrode polarity
Reverse electrode polarity (refer to manufacturer's instructions)
Poor grounding (earthing) connection
Fasten earthing clamps directly to workpiece
Setup parameters not ideal for selected welding process
