3.05 Gas Connections
Connecting Gas Supply to Unit
The connection is the same for compressed air or high
pressure cylinders. Refer to the following subsections
if an optional air line filter is to be installed.
1. Connect the air line to the inlet port. The il-
lustration shows typical fittings as an example.
NOTE
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.

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 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 adjust-
able 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)
