What to do if GAS LED is OFF and FAULT and MIN pressure indicators are flashing on my Thermal Dynamics Welding System?
- B
  Brian WhiteAug 1, 2025
  If the GAS LED is OFF, and the FAULT and MIN pressure indicators are flashing, it could be due to several reasons: * The gas supply might not be connected, so ensure it is properly connected to the unit. * The gas supply might not be turned ON, so turn it ON. * The gas supply pressure might be too low, so set the air supply inlet pressure to 120 psi.

  If the ON/OFF switch is ON, but the A/C indicator does not light, consider these potential causes: 1. The primary power disconnect might be in the OFF position. If so, turn the primary power disconnect switch to the ON position. 2. The primary fuses or breakers might be blown or tripped. Have a qualified person check the primary fuses or breakers and connect the unit to a known good primary power receptacle. 3. The unit's internal fuse might be blown. Replace the fuse. If it blows again, the unit may need professional attention.

What should I do if FAULT and 75 PSI indicators are flashing on my Thermal Dynamics CutMaster 40MM?
- P
  Patrick MoraAug 11, 2025
  If the FAULT and 75 PSI indicators are flashing, it could mean that the start signal is 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. Release the START signal source.

Why are the Fault and 65 PSI indicators flashing on my Thermal Dynamics CutMaster 40MM?
- M
  Michael ArroyoAug 16, 2025
  If the Fault indicator and the 65 PSI indicator are flashing, it could be due to improper input voltage. Check for proper primary input voltage. Also, have a qualified person check the primary voltage to ensure it meets the unit requirements.

What does it mean when TEMPERATURE indicator is ON and FAULT indicator is flashing on Thermal Dynamics CutMaster 40MM?
- C
  Colleen AndrewsAug 27, 2025
  If the TEMPERATURE indicator is ON and the FAULT indicator is flashing, it could be due to: 1. Obstructed airflow through or around the unit. 2. Exceeding the unit's duty cycle. If this is the case, allow the unit to cool.
