25 codes
E-1

Overtemperature condition detected in the welder.

E-2

Input voltage is out of the acceptable operating range.

E-3

Input Voltage Error — input voltage does not match the unit's operating requirements.

E-3

Wire feed motor is experiencing a fault condition.

E01

Over-temperature warning indicating the unit has exceeded safe operating temperature.

E02

Over-voltage error indicating input voltage exceeds specified range.

E03

Undervoltage detected.

E04

Overtemperature warning.

E1

Overcurrent Protection Activated — excessive current draw detected by the machine.

E2

Overvoltage Protection Activated — input voltage exceeds acceptable range.

Help 14

Unit not ready. Primary circuit bus not up to full power.

Help 16

Secondary clamp voltage too high.

Help 20

Indicates that the power supplies for the primary drives have failed.

Help 21

Indicates voltage or current feedback has been detected with contactor off.

Help 22

Voltage and current not present with contactor on.

Help 24

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.

Help 30

Indicates a short or open in the thermal protection circuitry located in the input inductor of the unit.

Help 31

Indicates a malfunction in the primary power circuit caused by an overcurrent condition in the primary IGBT switching circuit.

Help 32

Indicates a short or open in the thermal protection circuitry located on the left side of the unit.

Help 34

Indicates a short or open in the thermal protection circuitry located on the right side of the unit.

Help 8

Indicates a malfunction in the secondary power circuit of the unit with a high open circuit condition.

LED 5 blinks 3 times

Normal startup indication — DIP switch is set correctly and feeder is working properly.

LED 5 green

Feeder is connected with electrode negative polarity.

LED 5 red

Feeder is connected with electrode positive polarity.

WARNING: Overuse can cause OVERHEATING.

The device may overheat if used excessively or without proper cooling periods, exceeding its rated duty cycle.
