Using High Pressure Air Cylinders

When using high pressure air cylinders as the air supply:

1. Refer to the manufacturer’s specifications for instal-

lation and maintenance procedures for high pressure

regulators.

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 300

scfh (141.5 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.
