What to do if the Thermal Dynamics Cutter's FAULT and 75 PSI indicators are flashing?

If the FAULT and 75 PSI indicators are flashing on your Thermal Dynamics Cutter, it could be due to several reasons. First, the start signal might be active when the ON/OFF SWITCH is turned to the 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. Try releasing the START signal source. Another possible cause is a problem in the torch and leads switch circuit, in which case you should replace the torch and leads.
