SECTION 8 – TROUBLESHOOTING 8-1. Troubleshooting A. Welding Trouble Remedy No weld output. Check Amperage control setting. Check weld connections. Reduce load and allow generator Over-Temp switch TP1 to reset. TP1 opens if generator overheats. Check engine speed, and adjust if necessary (see Section 7-4). Output stops if engine speed is too low. Be sure all equipment is disconnected from receptacles when starting unit.
