Qualifications and Requirements
2
XPR300 Instruction Manual 809480 47
Code conformity
 All installer or user-supplied equipment must meet applicable national and local codes for
supply gas and supply gas plumbing. Contact a licensed plumber for more information
about the codes in your location.
 Any installation, modification, or repair of supply gas equipment or plumbing systems must
be done by a licensed plumber.
Plumbing for supply gases
As an installer or user, you must install the supply gases and supply gas plumbing for your cutting
system.
 You can use flexible hoses that are designed to carry the appropriate gas and are rated for
the correct pressure. Other hoses can crack and 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
for cutting. An explosion or fire can occur if hydrogen is not removed.
