If the FAULT and 70 PSI indicators are flashing, it could be due to the following: * The shield cup might be loose. Hand tighten the shield cup until it is snug. * The torch might not be properly connected to the power supply. Ensure the torch ATC is securely fastened to the unit. * There could be a problem in the torch and leads PIP circuit, consider replacing the torch and leads.
