What to do if FAULT and 75 PSI indicators are flashing on Thermal Dynamics CUTMASTER 102?

If the FAULT and 75 PSI indicators are flashing on your Thermal Dynamics Welding System, it means that the start signal is active when the ON/OFF SWITCH is turned to ON position. This can happen if the hand torch switch or hand pendant switch is held closed, or if the CNC START signal is active low. Release the START signal source. Alternatively, there may be a problem in the torch and leads switch circuit, which would require replacing the torch and leads or returning them to an authorized service center. If neither of these resolves the issue, there may be failed components in the unit, necessitating a return to an authorized service center for repair or replacement.
