How to set the regulators
This procedure is for when the regulators need to be adjusted in the field.
The N
2
and Ar OptiMix gas connect console (078633) regulators are set at Hypertherm before the
regulators are installed into 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 6.9bar (100psi) on
the outlet. There is a 1.6 mm (0.063 inch) orifice downstream.
When to adjust regulators:
If your N
2
Shield inlet (P4) pressure is above 7.5bar (110psi) or below 6.2bar (90psi).
If your Ar Shield Inlet (P4) pressure is above 7.5 bar (110 psi) or below 6.2 bar (90 psi).
