Troubleshooting for low shield water pressure

Diagnostic code 532

Diagnostic code 532 identifies when the shield water pressure supplied to the cutting system is less than the required range. This condition can cause system shutdown or poor cut quality. Examination of water hoses, fittings, regulators, and possibly the use of a booster water pump can be necessary.

Corrective action

  1. Make sure that the shield water pressure supplied to the cutting system is between 2.76 bar – 7.93 bar (40 psi – 115 psi).

    If the pressure is less than 2.76 bar (40 psi), a "booster" water pump can be necessary to prevent system shutdown or bad cut quality. Refer to Shield-water requirements (VWI and OptiMix).

  2. Examine all water hoses and water hose inlet fittings for:
    • Damage or kinks that can restrict flow
    • Leaks that can decrease pressure
  3. Replace any hoses that have damage or kinks.
  4. Put the hoses in a different position if you find kinks that can be fixed.
  5. Replace any fitting that has damage.
  6. Tighten loose connections if found.
  7. Examine water regulators for debris that can block the flow path.
  8. Adjust the inlet water pressures to a minimum of 2.77 bar (40 psi) when cutting, if necessary.

    The Hypertherm®-supplied regulator that is connected to the gas connect console is set at the factory. Do not adjust this regulator.

  9. If you cannot find or correct the problem, speak to your cutting machine supplier or regional Hypertherm Technical Service team.
