Installing Optional Two - Stage Air Filter Kit
This optional two - stage air line filter is also for use on
compressed air shop systems. Filter removes moisture and
contaminants to at least 5 microns.
Connect the air supply as follows:
1. Attach the Two Stage Filter bracket to the back of the
power supply per instructions supplied with the filter
assembly.
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.
2. Connect the two stage filter outlet hose to the inlet port
of the Regulator / Filter Assembly.
3. Use customer - supplied fittings to connect the air line
to the Filter. A 1/4 NPT to 1/4" hose barbed fitting is
shown as an example.

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
