No welding current
Power source is switched on, indicator for the selected welding process is lit, overtemper-
ature indicator lit
Cause: Power module error
Remedy: Turn off the power source, then turn it on again.
If the error occurs frequently, contact After-Sales Service
Faulty operation Poor ignition properties during MMA welding
Cause: Incorrect welding process selected
Remedy: Select "MMA welding" or "MMA welding with Cel electrode" process
Cause: Starting current too low; electrode sticking during ignition
Remedy: Increase starting current using HotStart function
Cause: Starting current too high; electrode consumed too quickly during ignition or is
generating a lot of spatter
Remedy: Reduce starting current using SoftStart function
In some cases, arc breaks during welding
Cause: Electrode (e.g. grooved electrode) voltage too high
Remedy: If possible, use alternative electrode or a power source with more welding
power
Cause: Break voltage (Uco) set too low
Remedy: Increase break voltage (Uco) in Setup menu
Rod electrode tends to stick
Cause: Value of arc-force dynamic parameter (MMA welding) set too low
Remedy: Increase value of arc-force dynamic parameter
Poor weld properties
(severe spattering)
Cause: Incorrect electrode polarity
Remedy: Reverse electrode polarity (refer to manufacturer's instructions)
Cause: Poor grounding (earthing) connection
Remedy: Fasten earthing clamps directly to workpiece
Cause: Set-up parameters not ideal for selected welding process
Remedy: Select best setting in set-up menu for selected welding process
Tungsten electrode melting
Tungsten inclusions in base metal during the ignition phase
Cause: Incorrect tungsten electrode polarity
Remedy: Connect the TIG welding torch to the (-) current socket
Cause: Incorrect (or no) shielding gas
Remedy: Use inert shielding gas (argon)
