For LAF and TAF: 168 = Motor M1 (Wire feeder motor), 169 = Motor M2 (Travel motor).
1. Check the motor cables. Replace the pulse transducer.
169 A motor has stopped
There are no pulses from the motor pulse transducer.
For LAF and TAF: 168 = Motor M1 (Wire feeder motor), 169 = Motor M2 (Travel motor).
1. Check the motor cables. Replace the pulse transducer.
2310 Current servo saturation
The power source has temporarily delivered maximum current.
1. If the error persists, try lowering the weld data.
3205 High DC voltage
1. Check if the main voltage is too low or too high.
4201 High temperature
The power source has overheated. Welding is cancelled. Welding is permitted again when the
temperature falls below the maximum temperature parameter.
1. Check that the cooling air inlets or outlets are not obstructed or clogged with dirt.
2. Check the duty cycle being used, to make sure that the equipment is not being overloaded.
4202 High temperature
The power source has overheated. Welding is cancelled. Welding is permitted again when the
temperature falls below the maximum temperature parameter.
1. Check that the cooling air inlets or outlets are not obstructed or clogged with dirt.
2. Check the duty cycle being used, to make sure that the equipment is not being overloaded.
4203 High temperature
The power source has overheated. Welding is cancelled. Welding is permitted again when the
temperature falls below the maximum temperature parameter.
1. Check that the cooling air inlets or outlets are not obstructed or clogged with dirt.
2. Check the duty cycle being used, to make sure that the equipment is not being overloaded.
5010 High inductance
Inductance is too high, depending on long welding cables and/or high weld data.
1. Adjust the welding data.
8117 Lost contact with the unit
Lost contact with a unit.
1. Check wiring and the connector between the control unit and power source.
8411,
sub-
code 0
Wire speed motor error
A motor cannot maintain its speed. Welding stops.
1. Check that the wire feed has not jammed or runs too fast. If the error persists, send for a service
technician.
