Manual 0-2746 3-5 INSTALLATION
C. Gas Connections
The gas supply is connected to the Pressure Regulator /
Filter Assembly installed on the rear of the unit. The con-
nection is the same for compressed air or high pressure
gas cylinders.
Connect the gas supply as follows:
1. Use customer-supplied fittings to connect the gas line
to the power supply Regulator/Filter Assembly. Typi-
cal fittings are shown as an example. Other fittings
may be used.
2. If an optional air line filter is to be installed, refer to
subsection D.
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:

D. Optional Air Line Filter Installation
Filtering is required when using air from a compressor to
insure that moisture and debris from the supply hose does
not enter the torch. Although the Regulator does have its
own filter, it is recommended the optional Single - Stage
Air Filter or optional Two Stage Air Line Filter be installed
for improved filtering. Gas connections to optional fil-
ters are shown in Figures 3-8 and 3-9.
