Miller
33 codesOvertemperature condition detected in the welder.
Input voltage is out of the acceptable operating range.
Input Voltage Error — input voltage does not match the unit's operating requirements.
Wire feed motor is experiencing a fault condition.
Over-temperature warning indicating the unit has exceeded safe operating temperature.
Over-voltage error indicating input voltage exceeds specified range.
Undervoltage detected.
Overtemperature warning.
Overcurrent Protection Activated — excessive current draw detected by the machine.
Overvoltage Protection Activated — input voltage exceeds acceptable range.
Unit not ready. Primary circuit bus not up to full power.
Secondary clamp voltage too high.
Indicates that the power supplies for the primary drives have failed.
Voltage and current not present with contactor on.
Indicates a power supply to the control and interface board PC6 failure. Possible cause is a short in Pin A or Pin B of the remote control.
Indicates a short or open in the thermal protection circuitry located in the input inductor of the unit.
Indicates a malfunction in the primary power circuit caused by an overcurrent condition in the primary IGBT switching circuit.
Indicates a short or open in the thermal protection circuitry located on the left side of the unit.
Indicates a short or open in the thermal protection circuitry located on the right side of the unit.
Malfunction in the primary power circuit caused by an overcurrent condition in the primary IGBT switching circuit.
Indicates a malfunction in the primary power circuit caused by an overcurrent condition in the primary IGBT switching circuit.
Voltage or current feedback has been detected while the contactor is off, suggesting a malfunction in the internal PID board.
Indicates that voltage or current feedback has been detected while the contactor is off, suggesting a malfunction in the internal PID board.
Open in the thermal protection circuitry located on the top heat sink.
Signifies an open in the thermal protection circuitry located on the top heat sink.
Indicates that the torch trigger has not been released.
Indicates that the torch trigger has not been released.
Denotes a failure in the SCR (Silicon-Controlled Rectifier).
Denotes a failure in the SCR (Silicon-Controlled Rectifier).
Normal startup indication — DIP switch is set correctly and feeder is working properly.
Feeder is connected with electrode negative polarity.
Feeder is connected with electrode positive polarity.
Indicates that voltage or current feedback has been detected while the contactor is off, suggesting a malfunction in the internal PID board.
