Troubleshooting for process-gas inlet pressure faults in the
TorchConnect console for OptiMix systems
Diagnostic codes 702, 705, 769, and 770
The 702, 705, 769, and 770 diagnostic codes identify a problem with the process-gas inlet pressure.
Process-gas inlet pressure has an effect on cut quality, cut speed, and consumable life.
The nitrogen (N
2
) and Argon (Ar) gas regulators inside the OptiMix gas connect console are set at
Hypertherm before the regulators are installed in the gas connect console. The regulators are set in a
dynamic condition, when gas is flowing, with 7.9 bar – 8.6 bar (115 psi – 125 psi) on the inlet and 6.9
bar (100 psi) on the outlet. A downstream 1.6 mm (0.063 inch) orifice is part of both regulator setting
configurations.
It can be necessary to adjust the regulators if the following conditions occur:
■
The N
2
shield inlet (P4) pressure is more than 7.5 bar (110 psi) or less than 6.2 bar (90 psi).
■
The Ar shield inlet (P4) pressure is more than 7.5 bar (110 psi) or less than 6.2 bar (90 psi).

702 For a minimum of 200 milliseconds, the nitrogen
(N
2
) inlet pressure (P4) in the TorchConnect con-
sole is less than 5.52 bar (80 psi) or more than 8.61
bar (125 psi).
705 For a minimum of 200 milliseconds, the argon (Ar)
inlet pressure (P4) in the TorchConnect console is
less than 5.52 bar (80 psi) or more than 8.61 bar
(125 psi).
769 Line B Argon inlet pressure (P1) is less than 5.52
bar (80 psi) or more than 8.62 bar (125 psi).
770 Line B N
2
inlet pressure (P1) is less than 5.52 bar
(80 psi) or more than 8.62 bar (125 psi).
