      Anthony JacksonAug 1, 2025
      If the GAS LED is OFF, and the FAULT and MIN pressure indicators are flashing, check if the gas supply is connected and turned on. Ensure the gas supply inlet pressure is set to 120 psi. Also, check the AIR PRESSURE CONTROL regulator setting, and adjust it as needed.

      If the FAULT and 75 PSI indicators are flashing, the start signal might be active when the ON/OFF switch is turned on. 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.

      If the ON/OFF switch is ON but the A/C Indicator doesn't light, first ensure the primary power disconnect is in the ON position. Then, have a qualified person check the primary fuses/breakers. If they are fine, connect the unit to a known good primary power receptacle. If the issue persists, the unit's internal fuse may be blown and needs replacement.

    Why TEMPERATURE indicator is ON and FAULT indicator is flashing on my Victor Cutmaster 20mm Cutter?
    • Y

      If the TEMPERATURE indicator is ON and the FAULT indicator is flashing, it could be due to obstructed airflow through or around the unit. Refer to clearance information in section 2.04. Alternatively, the unit's duty cycle might have been exceeded; in this case, allow the unit to cool.

      If the FAULT and 70 PSI indicators are flashing, ensure the shield cup is snug by hand-tightening it. Also, verify that the torch ATC is securely fastened to the unit.

    What to do if Fault indicator and 65 PSI indicator are flashing on my Victor Cutmaster 20mm?
    • A
      Alexis DonaldsonAug 26, 2025
      If the Fault indicator and 65 PSI indicator are flashing, check for proper primary input voltage. Have a qualified person check the primary voltage to ensure it meets the unit requirements, as detailed in section 2.05.
