If the FAULT and 70 PSI indicators are flashing, the possible causes are: * The shield cup is loose; hand tighten it until it is snug. * The torch is not properly connected to the power supply; make sure the torch ATC is securely fastened to the unit. * There is a problem in the torch and leads PIP circuit; consider replacing the torch and leads. * There may be failed components in the unit.
