700 The F5 inlet pressure (P6) in the gas connect con-
sole (only for VWI or OptiMix) is less than 5.52 bar
(80 psi) or more than 9.3 bar (135 psi).

Corrective action
1. During test cutflow and test preflow, look at the CNC or XPR web interface to identify the gas inlet
pressure in the gas connect console.
Look at the F5 inlet pressure (P6) for code 700.
2. Make sure that the gas inlet pressures inside of the gas connect console are sufficient as specified in
Permitted inlet pressures to gas connect consoles on page 349.
3. When gases are flowing and the pressure that you measured is not in the permitted range, use the
regulators to increase the pressure, if necessary.
Do not exceed the recommended pressures.
4. If the pressure stays too low, examine the gas hoses and gas inlet fittings for:
□
Damage or kinks that can restrict flow
□
Leaks that can decrease pressure
5. Replace the hoses if you find damage or kinks.
6. Put the hoses in a different position if you find kinks that can be fixed.
7. Replace fittings that have damage.
8. Tighten loose connections if found.
9. If you cannot find or correct the problem, speak to your cutting machine supplier or regional
Hypertherm Technical Service team.
Troubleshooting for low inlet pressure for water
Diagnostic code 701
Diagnostic code 701 occurs because water inlet pressure in the gas connect console is less than the
permitted range. Do a check of the pressures, examine the water hoses and fittings, and make sure that
the shield water quality is good.
