Corrective action

  1. Remove the power from the cutting system.
  2. Examine the pressure transducer for the diagnostic code that you see.
    For example:
    • If the code shows P1-TCC, examine the P1 pressure transducer in the TorchConnect console.
    • If the code shows P6-GCC, examine the P6 pressure transducer in the gas connect console.
  3. Make sure that the pressure transducer is correctly connected to:
    • TorchConnect console control Printed Circuit Board (PCB)
    • Gas connect console control PCB
  4. Install the pressure transducer correctly if you find loose or incorrect connections.
  5. If you find damage, replace the control PCB that has damage.
  6. Replace the pressure transducer.
  7. If you cannot find or correct the problem, speak to your cutting machine supplier or regional Hypertherm® Technical Service team.
