High-pressure gas cylinders
| Warning | |
|---|---|
 | GAS CYLINDERS CAN EXPLODE IF THEY HAVE DAMAGE
Gas cylinders contain gas under high pressure. If a cylinder has
damage, it can explode.
For high pressure regulators, comply with the manufacturer’s
guidelines for safe installation, operation, and maintenance.
Before operating a plasma power supply with compressed gas, read the
safety instructions in the Safety and Compliance Manual (80669C).
If you do not comply with these safety instructions, personal injury or
equipment damage can occur.

 | EXPLOSION HAZARD – CUTTING WITH FLAMMABLE OR OXIDIZING
GASES
Flammable and oxidizing gases can cause explosive conditions during
plasma cutting operations.
Do not use flammable or oxidizing gases with Powermax
systems.
An example of an oxidizing gas is oxygen. Examples of flammable gases
are acetylene, propylene, methane, and pure hydrogen. Refer to the Safety
and Compliance Manual (80669C).

cut with this plasma power supply. Refer to Hypertherm plasma power supply ratings for
requirements on gas quality. Do NOT use oxygen to cut with
Powermax®
systems.

- F5 (stainless steel only)
If you use high-pressure gas cylinders as the gas
supply:
- Refer to the manufacturer’s specifications for installation and maintenance procedures of high-pressure regulators.
- Make sure that the cylinder has an adjustable high-pressure regulator with the
following capabilities:
- Gas outlet pressures up to 9.3 bar (135 psi). Never use more than the maximum gas pressure of 9.3 bar (135 psi).
- Gas flow rate of 210 slpm (450 scfh)
- Make sure that the cylinder valves are clean and free of oil, grease, and other contaminants. Open each cylinder valve just long enough to blow out any dust that is possibly present.
- Connect the supply hose correctly to the cylinder.
- Comply with inlet gas pressure requirements (while gas is flowing).
