Optional Single - Stage Filter Installation
Using High Pressure Air Cylinders
When using high pressure air cylinders as the air supply:
1. Refer to the manufacturer’s specications 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 mate-
rial. Briey 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
ows 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 cylin-
der regulator.
Supply hose must be at least 1/4
inch (6 mm) I.D.
For a secure seal, apply thread
sealant to the tting threads, accord-
ing to manufacturer's instructions.
Do Not use Teon tape as a thread
sealer, as small particles of the tape
may break off and block the small air
passages in the torch.
Installing Optional Two - Stage Air Filter Kit
This optional two - stage air line lter is also for use on
compressed air shop systems. Filter removes moisture
and contaminants to at least 5 microns.
