INSTALLATION PROCEDURES
B. Gas Connection
The gas supply is connected to the rear of the Power Sup-
ply.
CAUTION
The air supply must be free of oil, moisture, and
other contaminants. Excessive oil and moisture
may cause double-arcing, rapid tip wear, or even
complete torch failure. Contaminants may cause
poor cutting performance and rapid electrode wear.
NOTE
Filtering is required when using air from a com-
pressor to insure that moisture and debris from the
supply hose does not enter the torch. It is recom-
mended to order the Optional Two Stage Air Line
Filter for air filtering.
1. Locate the 1/4 NPT to #4 (6mm) hose barb fitting
shipped inside the Torch Spare Parts Kit.
NOTE
A barb fitting is provided for connection of the gas
supply hose to the rear of the Power Supply. The
fitting is placed in the Spare Parts Kit for ship-
ment.
2. Depending on the options installed at the factory, in-
stall the supplied barb fitting into the gas connector
fitting input or the IN port of the Optional Two Stage
Air Filter Assembly at the rear panel.
3. Tighten the barb fitting.
4. Place an adjustable hose clamp over the gas supply
hose.

5. Refer to the following when using high pressure gas
cylinders as the gas supply:
CAUTION
Pressure should be set at 100 psi (6.9 bar or 690
kPa) at the high pressure gas cylinder regulator.
a. Refer to the manufacturer’s specifications for in-
stallation and maintenance procedures for high
pressure gas regulators.
b. Examine the cylinder valves to be sure they are
clean and free of oil, grease or any foreign mate-
rial. Momentarily open each cylinder valve to blow
out any dust which may be present.
c. 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 up
to 300 scfh (141.5 lpm).
6. Slide the gas supply hose over the barb fitting installed
in Step 2.
7. Secure the gas supply hose in place with the adjust-
able hose clamp.
NOTE
Supply hose must be at least #4 hose (1/4 in or 6
mm I.D.).
