Regulators for supply gases
The installer or user must supply the gas regulator (regulators) for the cutting system.
CAUTION
INCORRECT HOSES, CONNECTIONS, OR FITTINGS CAN CAUSE DAMAGE AND BAD
PERFORMANCE
All hoses, hose connections, and hose fittings used for supply-gas plumbing must be designed for use
with the appropriate gas and pressure rating. Incorrect hoses, hose connections, or hose fittings can
crack or leak.
NEVER connect a supply gas to a hose, connection, or fitting that is not designed for that gas type or
pressure.
A replacement hose, connection, or fitting must meet all applicable regulations and codes.
Non-compliant hoses, hose connections, or hose fittings can crack or leak.The wrong fittings can cause
malfunctions with the internal valves because contaminants can enter the valves through damaged or
loose fittings.
NOTICE
DIRTY, OILY AIR CAN CAUSE DAMAGE TO THE AIR FILTER BOWL
Some air compressors use synthetic lubricants that contain esters. Esters can damage the
polycarbonates in the air filter bowl. Add additional gas filtration if necessary.
CAUTION
LOW-QUALITY REGULATORS CAN REDUCE PERFORMANCE AND CUT QUALITY
Do not use low-quality gas regulators. They do not provide consistent supply-gas pressure. Low-quality
gas regulators can also reduce system performance and decrease cut quality.
