E10
Overcurrent Protection
The machine is outputting more current than it is rated for. This is likely due to internal fault.
Possible Solution: Power down and restart machine.
E31
Under Voltage Protection Voltage source for machine is too low. This is likely caused by an extension cable.
Possible Solution: Remove any extension cables and check power socket and machine power wire. Attempt weld on a different power circuit.
E32
Over Voltage Protection
Voltage source for machine is too high.
Possible Solution: Remove any extension cables and check power socket and machine power wire. Attempt weld on a different power circuit.
E34
Under Voltage Error
Power supply voltage is too low. This is likely caused by internal fault.
Possible Solution: Remove any extension cables and check power socket and machine power wire. Attempt weld on a different power circuit.
E60
Rectifier Overheat
Internal temperature is too high. This is likely caused by reaching duty cycle limit.
DO NOT TURN OFF MACHINE! Wait for machine to cool down and for indicator warning to turn off.
E61
IGBT Overheat
Internal temperature is too high. This is likely caused by reaching duty cycle limit.
DO NOT TURN OFF MACHINE! Wait for machine to cool down and for indicator warning to turn off.
RED VRD ICON
Abnormal VRD
The No-Load voltage is too high. This is likely caused by VRD fault.
Possible Solution: Power down and restart machine.
THERMAL OVERLOAD
OVERCURRENT LIMIT
VRD - NORMAL - ABNORMAL
Typically caused by duty cycle
limits.
DO NOT POWER OFF
MACHINE.
Wait for the machine
to cool down and for indicator to
turn off before welding again.
If you wish to reset the machine to factory settings,
press and hold the Welding Mode Selection Button for 5
seconds
to restore factory settings.
After pressing and holding for 5 seconds, the display window will count down from 3. When the countdown ends,
the factory settings are restored. If the button is released before the countdown ends, the factory restore will not
take place.
*WARNING THIS CANNOT BE UNDONE*
After attempting the possible solutions listed in the chart above please contact UNIMIG Support
Services if you are still experiencing issues with your machine.
Typically caused by internal fault
of machine. Restart machine
and attempt to weld again.
If problem persists contact
UNIMIG Service Support.
Voltage Reduction Device is a
safety feature for MMA welding. If
this indicator turns red restart the
machine. If it persists contact UNIMIG
Service Support.
WARNING: There are extremely dangerous voltage and power levels present inside this unit. Do not attempt to diagnose
or repair unit by removing external cover unless you are an authorised repair agent for UNIMIG.
