B. Using Industrial Compressed Air In Gas Cylinders
When using industrial compressed air in gas cylinders
as the gas supply:
1. Refer to the manufacturer’s specifications for
installation and maintenance procedures for high
pressure gas regulators.
2. Examine the cylinder valves to be sure they are
clean and free of oil, grease or any foreign mate-
rial. Briefly open each cylinder valve to blow out
any dust which may be present.
3. The cylinder must be equipped with an adjust-
able high-pressure regulator capable of outlet
pressures up to 100 psi (6.9 bar) maximum and
flows of at least 250 scfh [Standard cubic foot
per hour] (120 lpm) [liter per minute].
4. Connect gas supply hose to the cylinder.
NOTE
Pressure should be set at 100 psi (6.9 bar) at
the high pressure gas cylinder regulator.
Supply hose must be at least 1/4 inch (6mm)
internal diameter.
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 gas pas-
sages in the torch.
