Power module error
Turn off the power source, then turn it on again.
If the error occurs frequently, contact After-Sales Service
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
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
Set-up parameters not ideal for selected welding process
Select best setting in set-up menu for selected welding process
Incorrect tungsten electrode polarity
Connect the TIG welding torch to the (-) current socket
Incorrect (or no) shielding gas
Use inert shielding gas (argon)
