Troubleshooting
18Fault codes
| Code | Meaning | Cause | Remedy |
|---|---|---|---|
| 21 | Device that controls sequence of the welding operation halted due to an error | Weld Terminals Remote: Re-trigger to recover from error; Weld Terminals Local: Toggle Remote/Local Switch to recover from error | |
| 31 | Primary Over Current | Input power (voltage and frequency) incorrect; primary reconnect not properly configured for the input voltage | Check the input power (voltage and frequency); verify the primary reconnect is properly configured for the input voltage; machine needs to be turned off and back on to reset |
| 36 | Thermal Fault | Machine shut off output due to elevated internal temperatures; material blocking intake or exhaust louvers; dirt from the fan; welding output ratings may have been exceeded | Check for material blocking intake or exhaust louvers; blow air in the rear louvers to clear dirt from the fan (Note: The Fan As Needed circuitry automatically shuts off the fan 5 minutes after welding has stopped); allow the machine to cool down and reset |
| 45 | VRD™ Voltage limit exceeded | During OCV, the voltage exceeded allowable VRD™ levels | Machine needs to be turned off and back on to reset |
| 712 | Communication Fault | CAN communication between the control pcb and switch pcb has been interrupted; dip switch settings not correct for the input voltage | Verify dip switch settings are correct for the input voltage; inspect harness for damage / loose connections |
| 713 | Input Power Misconnect. Supply Voltage is too high | Occurs upon power up when the supply voltage to the switch pcb exceeded acceptable levels | Verify the primary reconnect is properly configured for the input voltage; machine needs to be turned off and back on to reset |
| 714 | Input Power Misconnect. Supply Voltage is too low | Occurs upon power up when the supply voltage to the switch pcb is below acceptable levels | Verify the primary reconnect is properly configured for the input voltage; machine needs to be turned off and back on to reset |
| 715 | Under Voltage Lockout | The supply voltage to the switch pcb is below acceptable levels | Machine needs to be turned off and back on to reset |
| 719 | Switch PCB Error | Machine needs to be turned off and back on to reset |
Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| Major physical or electrical damage is evident when the sheet metal covers are removed | Contact your local authorized Lincoln Electric Field Service facility for technical assistance | |
| Machine won't weld, can't get any output | Displays show an Err ### | See the fault section for corrective action |
| Machine won't weld, can't get any output | Thermal LED is lit | Refer to the thermal section |
| Machine won't weld, can't get any output | Output terminals are in remote control | Switch to "ON" and check for output voltage; if output voltage is now present check for correct remote control connection and operation |
| Thermal LED is lit | Improper fan operation; material blocking intake or exhaust louvers; dirt from the fan | Check for proper fan operation; check for material blocking intake or exhaust louvers; blow air in the rear louvers to clear dirt from the fan (Note: The Fan As Needed circuitry automatically shuts off the fan 5 minutes after welding has stopped) |
| Thermal LED is lit | Welding output ratings may have been exceeded | Allow the machine to cool down and reset |
| Wire feeder won't work. Apparently no power to wire feeder | 115/42V wire feeder switch (located on the case front) not properly set for the input voltage requirement of the wire feeder | Check the 115/42V wire feeder switch to make sure it is properly set for the input voltage requirement of the wire feeder |
| Wire feeder won't work. Apparently no power to wire feeder | Circuit breakers by the wire feeder receptacles tripped | Check circuit breakers by the wire feeder receptacles on the front of the machine. Reset if required |
| Wire feeder won't work. Apparently no power to wire feeder | Control cable between the power source and the wire feeder not continuous | Check the control cable between the power source and the wire feeder for continuity |
