Refer to Table 7 on page 46 for the recommended pressure and flow
rates.
If you suspect a cutting system gas leak:
1. Use the CNC screen or XPR web interface to select the command to do an automated gas leak
test. Test results and information will appear in the error log.

For information about how to do this, see the instruction manual that came
with your CNC.
2. See the error log for information and guidance about how to diagnose or troubleshoot a
possible gas leak.
WARNING
OXYGEN GAS CAN CAUSE A FIRE HAZARD
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. A fire can occur if oxygen is not removed.
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).
As an installer or user, you must supply the exhaust ventilation and flashback arrestors for
your cutting system. You can get them from your cutting machine supplier.
HYDROGEN GAS CAN CAUSE AN EXPLOSION OR FIRE
Hydrogen is a flammable gas that can cause an explosion or fire. 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.
Hypertherm recommends that you install an exhaust ventilation system to remove the
hydrogen-enriched atmosphere that can collect when hydrogen is used as the plasma gas
