A. Gas Requirements
WARNING
This unit not to be used with oxygen (O
2
).
Gases: Compressed Air or Nitrogen (N
2
) Only
Pressure: 70 psi (4.8 BAR or 418 kPa)
CAUTION
Maximum input gas pressure must not exceed 125
psi (8.6 BAR or 861 kPa)
Flow: Cutting - 400 scfh (188.7 lpm)
Gouging - 400 scfh (188.7 lpm)
CAUTION
Air supply must be free of oil, moisture, and other
contaminants. Excessive oil and moisture may
cause double-arcing, rapid tip wear, or even com-
plete torch failure. Contaminants may cause poor
cutting performance and rapid electrode wear.
B. Checking Air Quality
To test the quality of air, place the RUN/SET switch to
SET position, place a welding filter lens in front of the
torch and turn on the gas. Any oil or moisture in the air
will be visible on the lens. Do not initiate an arc!
C. Gas Connection
The gas supply is connected to the rear of the Power Sup-
ply. The connection is the same for compressed air or
high pressure gas cylinders.
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.
An air line filter is supplied as part of the Pressure Regu-
lator/Filter Assembly installed on the rear of the unit.
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 improved 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 input of the
Regulator/Filter Assembly or the Optional Two Stage
Air Filter Assembly.
3. Tighten the barb fitting.
4. Place an adjustable hose clamp, 1/4" (6.35mm) to 5/8"
(15.88mm)) over the gas supply hose.
