How to install and connect the supply gases
WARNING
If you use oxygen as the plasma gas for cutting, it can cause a potential
fire hazard due to the oxygen-enriched atmosphere that collects.
Hypertherm recommends that you install an exhaust ventilation system
to remove the oxygen-enriched atmosphere that can collect when
oxygen is used as the plasma gas for cutting.
Flashback arrestors are required to stop the spread of fire to the supply
gases (unless a flashback arrestor is not available for a specific gas or
pressure).
You must supply the flashback arrestors for your cutting system. You
can get them from your cutting machine supplier.
Hydrogen is a flammable gas that presents an explosion hazard. Keep
flames away from cylinders and hoses that contain hydrogen. Keep
flames and sparks away from the torch when using hydrogen as a
plasma gas.
Consult your local safety, fire, and building code requirements for the
storage and use of hydrogen.

CAUTION
All hoses, hose connections, and hose fittings used for supply gas plumbing must be designed
for use with the appropriate gas and pressure rating.
NEVER connect a supply gas to a hose, connection, or fitting that is not designed for that gas
type or pressure.
If you replace any fittings on the consoles, or if you use the wrong fittings, it can cause the
internal valves to malfunction because contaminants can get into the valves.
