b. Review the diagnostic code history for previous pressure-related codes that can indicate
where to look for flow or pressure problems.
c. If you identify a code for a pressure transducer (P1 or P2), exchange the transducers. See if
the code follows the transducer change. Replace the bad transducer if necessary. For
instructions, refer to “Replace a pressure transducer” in the XPR Replacement Parts
Procedures Field Service Bulletin (809970).
4. If you have a cutting system equipped with a OptiMix gas connect console, refer to Process-gas
inlet pressure in the torch connect console diagnostic codes (702, 705, 769, 770) for
OptiMix-equipped cutting systems on page 334.
5. If you have a Core or VWI gas connect console, or if the code continues, or if you cannot find or
resolve the problem with these corrective actions, contact your cutting machine supplier or
regional Hypertherm Technical Service team.
