Gas Requirements
The customer furnishes all gases and gas-supply regulators for the system. Use a high-quality, 2-stage pressure
regulator located within 10 ft (3 m) of the gas console. See Appendix C for gas regulator recommendations. Refer
to Section 2 for gas and flow specifications.
Caution: Gas supply pressures not within the specifications in Section 2 can cause poor
cut quality, poor consumable life and operational problems.
If the purity level of the gas is too low (or too high in the case of methane) or if there
are leaks in the supply hoses or connections,
• Cut speeds can decrease
• Cut quality can deteriorate
• Cutting thickness capability can decrease
• Parts life can shorten
