C. Using High Pressure Air Cylinders

When using high pressure air cylinders as the air supply:

1. Refer to the manufacturer’s specifications for installation and maintenance procedures for high pressure regula-

tors.

2. Examine the cylinder valves to be sure they are clean and free of oil, grease or any foreign material. Briefly open

each cylinder valve to blow out any dust which may be present.

3. The cylinder must be equipped with an adjustable high-pressure regulator capable of outlet pressures up to 100 psi (6.9 bar)

maximum and flows of at least 500 scfh (236 lpm).

4. Connect supply hose to the cylinder.

NOTE

Pressure should be set at 100 psi (6.9 bar) at the high pressure cylinder regulator.

Supply hose must be at least 1/4 inch (6 mm) I.D.

For a secure seal, apply thread sealant to the fitting threads, according to manufacturer's instructions. Do Not use
Teflon tape as a thread sealer, as small particles of the tape may break off and block the small air passages in the torch.
