What causes the ESAB Welding System's fault and 80 PSI indicators to flash with gas flow cycling ON and OFF?

If the fault and 80 PSI indicators are flashing and the gas flow is cycling ON and OFF on your ESAB Welding System, consider these potential causes: * The torch shield cup may be loose. Tighten it by hand, but do not overtighten. * The torch tip, electrode, or starter cartridge might be missing. Turn OFF the power supply, remove the shield cup, and install any missing parts. * The torch start cartridge could be stuck. Turn OFF the power supply, bleed down system pressure, remove the shield cup, tip, and start cartridge.

Replace the torch and leads or return them to an authorized service center for repair or replacement. ...
