If your Lincoln Electric Welding System won't weld, and the displays show an Err ###, check the fault section for corrective action. If the thermal LED is lit, refer to the thermal section. Also, if the output terminals are in remote control, switch to "ON" and check for output voltage. If output voltage is now present, verify the remote control connection and operation are correct.
Why isn’t my Lincoln Electric Welding System wire feeder working?
If your Lincoln Electric Welding System wire feeder isn’t working, there are a few things to check: * First, make sure the 115/42V wire feeder switch (located on the case front) is properly set for the input voltage requirement of the wire feeder. * Second, check the circuit breakers by the wire feeder receptacles on the front of the machine and reset if required. * Finally, check the control cable between the power source and the wire feeder for continuity.
How to fix the Thermal LED being lit on my Lincoln Electric Flextec 650x Welding System?
If the Thermal LED is lit on your Lincoln Electric Welding System, try the following: * Check for proper fan operation. * Check for any material blocking the intake or exhaust louvers. * Blow air into the rear louvers to clear any dirt from the fan. Also, consider that the welding output ratings may have been exceeded. If so, allow the machine to cool down and reset.
What to do if my Lincoln Electric Flextec 650x shows Error Code #36?
If your Lincoln Electric Welding System displays Error Code #36, check for material blocking the intake or exhaust louvers. Blow air in the rear louvers to clear dirt from the fan. Also, the welding output ratings may have been exceeded. Allow the machine to cool down and reset.
What does Error Code #713 mean on my Lincoln Electric Flextec 650x?
If your Lincoln Electric Welding System shows Error Code #713, verify the primary reconnect is properly configured for the input voltage. The machine needs to be turned off and back on to reset.
What does Error Code #714 mean on my Lincoln Electric Flextec 650x?
If your Lincoln Electric Welding System shows Error Code #714, verify the primary reconnect is properly configured for the input voltage. The machine needs to be turned off and back on to reset.
What does error code 21 mean on a Lincoln Electric Flextec 650x Welding System?
If your Lincoln Electric Welding System displays error code 21, and the weld terminals are set to remote, re-trigger to recover from the error. If the weld terminals are set to local, toggle the remote/local switch to recover from the error.
How to reset Error Code #31 on a Lincoln Electric Welding System?
To reset Error Code #31 on your Lincoln Electric Welding System, the machine needs to be turned off and back on.
What does error code 45 mean on a Lincoln Electric Flextec 650x?
If your Lincoln Electric Welding System shows Error Code #45, the machine needs to be turned off and back on to reset.
What to do if my Lincoln Electric Welding System displays Error Code #712?
If your Lincoln Electric Welding System displays Error Code #712, inspect the harness for damage and loose connections.
