High-pressure gas cylinders

GAS CYLINDERS CAN EXPLODE IF DAMAGED
Gas cylinders contain gas under high pressure. If damaged, a cylinder 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
Do not use flammable or oxidizing gases with Powermax systems. These gases can cause
explosive conditions during plasma cutting operations.
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).
You can use the gases that follow to cut with this plasma power supply. Refer to
power supply ratings

If you use high-pressure gas cylinders as the gas supply, make sure that you:
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.

