A. Gas Requirements
WARNING
This unit is not to be used with oxygen (O
2
).
Gases: Single Gas - Plasma/Secondary
Compressed Air Only
Pressure: 70 psi (4.8 bar)
CAUTION
Maximum pressure at inlet must not exceed 125 psi
(8.6 bar)
Flow: Cutting - 400 scfh (190 lpm)
Gouging - 400 scfh (190 lpm)
scfh = standard cubic feet per hour.
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!
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.
C. Connecting Gas Supply to Unit
The gas supply connects to the Regulator/Filter Assem-
bly on the rear of the unit. The connection is the same for
compressed air or high pressure gas cylinders. If an op-
tional air line filter is to be installed, refer to procedures
in subsection 3.06-D.
Connect the gas supply as follows:
1. Use customer-supplied fittings to connect the gas line
to the Regulator/Filter. A 1/4 NPT to 1/4" hose
barbed fitting is shown as an example. Other fittings
may be used. Install the fittings and tighten.

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 gas passages in the torch.
