Why is the front panel alarm lamp on my Stealth DIGI-TIG 320 AC/DC PULSE Welding System?
- Z
  zgrahamAug 19, 2025
  The front panel alarm lamp may be on due to several reasons: * **Overheat protection:** Reduce welding current output. * **Working time too long:** Reduce duty cycle and process. * **Over or low voltage protection:** This indicates power supply fluctuations. * **Too many machines using power:** Reduce the number of machines in use. * **Over-current protection:** There may be incorrect current in main circuit.
