Hypertherm XPR460 - Plumbing Requirements for Supply Gases

Table 9 - Air compressor requirements (continued)
Speak to your air compressor manufacturer if you operate the cutting system in temperatures colder than 3°C (37°F) or if you
are not sure that the air compressor complies with the ISO standard for air quality.
NOTICE
RUST IN GAS CYLINDERS CAN GET INTO THE GAS LINE
Rust can collect at the bottom of gas cylinders. If the rust mixes with the gas, it can get into the gas
line and decrease cut quality and performance.
When you move gas cylinders, make sure that you do not put them on their side, roll, or shake them.
Plumbing requirements for supply gases
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. A fire can occur if oxygen is
not removed.
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).
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.
