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.
