SAFETYOPERATIONMAINTENANCE SETUP
Air Supply
TO PREVENT SERIOUS INJURY AND DEATH FROM EXPLOSION:
Use only clean, dry, regulated, oil-free, compressed air or nitrogen gas with this Plasma Cutter.
Do not use oxygen, acetylene, carbon dioxide, combustible gases,
or any other bottled gas as a power source for this Plasma Cutter.
1� Use a compressor that is capable of
supplying 4�5 CFM @ 80 PSI�
2� Incorporate a filter, regulator with pressure gauge,
dryer, in‑line shutoff valve, and quick coupler for
best service� An in-line shutoff ball valve is an
important safety device because it controls
the air supply even if the air hose is ruptured.
The shutoff valve should be a ball valve
because it can be closed quickly.
Note: In humid locations, multiple dryers may need
to be incorporated to keep the air dry. MOISTURE
IN AIR SUPPLY MAY CAUSE SHORTENED
COMPONENT LIFE AND POOR CUT QUALITY.
Note: Do not use an oiler system with this
Plasma Cutter. The oil will mix with the air
being propelled, causing poor results.
3� Attach an air hose to the compressor’s air outlet�
Connect the air hose to the Air Inlet on the back
of the Plasma Cutter� Other components, such
as a coupler plug and quick coupler, will make
operation more efficient, but are not required�
Note: Air flow, and therefore Plasma Cutter
performance, can be hindered by undersized air
supply components�
The air hose must be long enough to reach
the work area with enough extra length to
allow free movement while working�
Setting Compressor's Air Pressure
1� Set the Plasma Cutter’s Power
Switch to the OFF position�
2� Turn on the air compressor according to
the manufacturer’s directions and allow it
to build up pressure until it cycles off�
3� Set the air compressor’s output air
pressure regulator between 90 - 120
PSI� Adjust the pressure gradually, while
observing the air pressure gauge�
4� Inspect the air connections for leaks�
Repair any leaks found�
Setting Plasma Cutter's Air Pressure
1� Plug in the Plasm Cutter, set the Power Switch
to the ON position and set the Air Switch to
SET AIR� There will be constant air flow�
2� Pull up on the Air Pressure Regulator
and set between 60 - 80 PSI, as observed
on the Air Pressure Gauge.
3� TEST AIR FLOW:
WARNING! Make sure Torch and
Cutting Tip are completely cool.
a� Hold Air Flowmeter firmly against end
of Cutting Tip, pointing Torch and Air
Flowmeter straight up� See Figure B.
b� The ball should float in the marked area on the
meter� If not, adjust air pressure, as needed,
while observing the Air Pressure Gauge�
4� IMPORTANT! After testing, set Air Switch
to CUT to allow normal operation�
