What to do if I have no weld output on my Miller Electric Big Blue 500D but generator power output is okay?
- P
  Paula NicholsonAug 15, 2025
  If your Miller Electric Welding System shows no weld output but the generator power output is functional at the AC receptacles, consider the following: * Verify the Ampere Range switch position. * Check the position of the optional Polarity switch. * Ensure the Amperage Adjust switch is in the Panel position, or if using Remote, ensure the switch is in the Remote position and the remote control is correctly connected to Remote Amperage Adjust receptacle RC13. Also, check and secure connections to Remote Amperage Adjust receptacle RC13. Finally, inspect fuse F2 and replace it if it's open.

Why is the electrode sticking to the workpiece more frequently during low voltage conditions on my Miller Electric Big Blue 500D Welding System?
- M
  Martin AllenAug 25, 2025
  If the electrode sticks to the workpiece more frequently during low voltage (short arc length) conditions when using your Miller Electric Welding System, it might be because circuit breaker CB4 is open. CB4 automatically resets when the fault is corrected.
