  If your welding machine exhibits these symptoms, consider the following: * Check for any loose connections inside the machine. * Inspect for an open circuit or loose contact at the output terminal joint. * If the overheating LED is illuminated: * The machine may be in an over-heating protection state, which will reset automatically once cooled. * Verify the thermal switch is functioning correctly and replace if damaged. * Ensure the thermal switch connection is secure; adjust if needed.

  If the electrode holder is overheating, it's likely that the rated current of the electrode holder is smaller than the actual working current. Replace it with a higher rated electrode holder.
