WARNING
Cutting with oxygen as the plasma gas can cause a potential fire hazard due to the oxygen-
enriched atmosphere that it creates. As a precaution, Hypertherm recommends that an exhaust
ventilation system be installed if you will be cutting with oxygen.
Oxygen, Nitrogen, or Argon-Hydrogen as Plasma Gas
From Source Supply to Gas Console
Refer to
Section 2
for gas specifications.
If
not
using hard plumbing to supply plasma gas to the gas console, we recommend using standard oxygen
hose with the system.
Note: If cutting with oxygen as the plasma gas, nitrogen must also be connected to the gas
console to achieve the proper oxygen/nitrogen mixtures in the preflow and cut flow
conditions.

Hose from the gas console to the motor valve console is provided by Hypertherm.
Shield Gas
