    How to fix Thermal Dynamics A80 Cutter when the A/C indicator doesn't light?
    • C
      Courtney RoweAug 16, 2025
      If the ON/OFF switch is in the ON position but the A/C indicator doesn't light, here's what to check: 1. Ensure the primary power disconnect switch is in the ON position. 2. Have a qualified person check the primary fuses/breakers, and connect the unit to a known good primary power receptacle. 3. Replace the internal fuse. If it blows again, return the Thermal Dynamics Cutter to an authorized service center for repair or replacement. 4. If the above steps don't resolve the issue, there may be faulty components in the unit, requiring service center attention.

    What to do if FAULT and 75 PSI indicators are flashing on Thermal Dynamics Cutter?
    • J
      John ValenciaSep 12, 2025
      If the FAULT and 75 PSI indicators are flashing on your Thermal Dynamics Cutter, it could be due to a start signal being active when the ON/OFF switch is turned on. The start signal can be active for one of the following reasons: * Hand torch switch held closed * Hand pendant switch held closed * CNC START signal is active low Release the START signal source. If the problem persists, it could be a problem in the torch and leads switch circuit, requiring replacement of the torch and leads or service by an authorized center. Failed components in the unit might also be the cause, necessitating repair or replacement at a service center.

    Why GAS LED is OFF, FAULT and MIN pressure indicators are flashing on Thermal Dynamics Cutter?
    • L
      Lisa ReedAug 26, 2025
      If the GAS LED is OFF, and the FAULT and MIN pressure indicators are flashing on your Thermal Dynamics Cutter, check the following: 1. Ensure the gas supply is connected to the unit. 2. Make sure the gas supply is turned ON. 3. Verify the gas supply pressure is adequate; set the air supply inlet pressure to 120 psi. 4. Check the AIR PRESSURE CONTROL regulator and adjust it to set the air pressure. If the issue persists after these checks, the unit may have failed components, requiring service by an authorized service center.

    Why TEMPERATURE indicator is ON and FAULT indicator flashing on Thermal Dynamics A80?
    • M
      Mariah MorrisSep 3, 2025
      If the TEMPERATURE indicator is ON and the FAULT indicator is flashing on your Thermal Dynamics Cutter, consider the following: 1. Ensure that air flow through or around the unit is not obstructed. 2. Allow the unit to cool if the duty cycle has been exceeded. If the issue persists, it may be due to failed components in the unit, requiring service by an authorized service center.

    • A
      Andrew BrownSep 5, 2025
      If the FAULT and 70 PSI indicators are flashing on your Thermal Dynamics Cutter, here's what you can check: 1. Ensure the Shield Cup is hand tightened until snug. 2. Make sure the torch ATC is securely fastened to the unit. 3. If the problem persists, the torch and leads PIP circuit may have an issue, potentially requiring replacement of the torch and leads or service by an authorized center. If none of these steps resolve the problem, the unit may have failed components, requiring service center attention.

    How to troubleshoot diminished torch cutting on Thermal Dynamics A80 Cutter?
    • A
      Aaron JonesSep 8, 2025
      If the torch cutting performance is diminished on your Thermal Dynamics Cutter, check the following: 1. Verify and adjust the current setting to the proper level. 2. Inspect the torch consumables and replace them as needed. 3. Check the connection of the Work Lead to the workpiece. 4. Reduce the cutting speed if the torch is being moved too fast. 5. Refer to "Check air quality" to address excessive oil or water in the torch. If the issue persists, there may be failed components in the unit, requiring service by an authorized service center.

    What to do if FAULT and 80 PSI indicators are flashing on Thermal Dynamics A80 Cutter?
    • J
      Jessica SmithNov 20, 2025
      If the FAULT and 80 PSI indicators are flashing and the gas flow is cycling ON and OFF on your Thermal Dynamics Cutter, try the following: 1. Tighten the torch shield cup by hand, but do not overtighten it. 2. Turn OFF the power supply, remove the shield cup, and install any missing torch tip, electrode, or starter cartridge. 3. Turn OFF the power supply, bleed down the system pressure, remove the shield cup, tip, and start cartridge. Check the start cartridge lower end fitting for free movement. Replace if the fitting does not move freely. If these steps don't resolve the issue, there may be an open conductor in the torch leads or a problem in the torch and leads switch circuit, potentially requiring replacement of the torch and leads. If none of these steps work, the unit may have f...
