INSTALLATION

D. Installing Optional Air Filter Kits

Additional filtering is recommended when using air from
a compressor to insure that moisture and debris from the
supply hose does not enter the torch. Although the Regu-
lator/Filter Assembly has its own filter, the optional fil-
ter kits are recommended for improved filtering.

1. Optional Single-Stage Air Filter Kit

This optional in-line air filter for use on compressed
air shop systems is highly effective at removing mois-
ture and particulate matter from the air stream to at
least 0.85 microns.

NOTE

For a secure seal, apply thread sealant to the fit-
ting threads, according to manufacturer's instruc-
tions. Do Not use Teflon tape as a thread sealer as
small particles of the tape may break off and block
the small gas passages in the torch. Connect the
gas supply as follows:

a. Attach the Single-Stage Filter Hose to the

Regulator/Filter Assembly inlet port as
shown.

b. Attach the Single-Stage Filter Assembly to the

filter hose.

c. Use customer-supplied fittings to connect the

gas line to the Filter. Typical fittings are shown
as an example. Install the fittings and tighten.

2. Optional Two-Stage Air Filter Kit

This optional two-stage air line filter is also for use
on compressed air shop systems. Filter removes mois-
ture and contaminants to at least 5 microns.

Connect the gas supply as follows:

a. Attach the Two Stage Filter bracket to the back

of the power supply.

NOTE

For a secure seal, apply thread sealant to the fit-
ting threads according to manufacturer's instruc-
tions. Do Not use Teflon tape as a thread sealer as
small particles of the tape may break off and block
the small gas passages in the torch.

b. Connect the two stage filter outlet hose to the

inlet port of the Regulator/Filter Assembly.

c. Use customer-supplied fittings to connect the

gas line to the Filter. Typical fittings are shown
as an example. Install the fittings and tighten.
