Duty cycle exceeded - device overloaded - fan running
Keep within duty cycle
Thermostatic automatic circuit breaker has switched off the device
Wait until the power source comes back on automatically at the end
of the cooling phase (do not switch off the device - the fan will cool it
down)
The fan in the power source is faulty
Contact After-Sales Service
Insufficient cooling air intake
Ensure adequate air supply
Air filter is dirty
Clean air filter
Power module error
Turn off the device, 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 ig-
nition or is generating a lot of spatter
Reduce starting current using SoftStart function
Break voltage (Uco) set too low
Increase break voltage (Uco) in Setup menu
Electrode (e.g. grooved electrode) voltage too high
If possible, use an alternative electrode or a power source with more
welding power
Value of arc-force dynamic parameter (MMA welding) set too low
Increase value of arc-force dynamic parameter
