ITEM 62204
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.
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.

PLASMA CUTTING TIPS:
Using a Plasma Cutter is a skill that
requires time and effort to do well.
The floor and surrounding area must not
be flammable. A clean concrete floor is
recommended.
The cutting process will eject
molten metal slag onto the floor, and it will
scatter for 8-10 feet or more in all directions.
Keep multiple ABC-type fire
extinguishers near work area.
a. Practice striking and maintaining an arc on
scrap work pieces before beginning work.
This will help determine the best settings for
the Plasma Cutter for the material at hand.
b. All metals that conduct electricity can
be cut, see Maximum Cutting Thickness
on page 5 for thickness capabilities.
Very thin or very thick metals are
more difficult to cut cleanly.
c. Set the air pressure between 60 and 80 PSI.
Increased air pressure will increase plasma
speed and cutting pressure. Air pressure and
amperage should be adjusted in tandem – air
pressure needs to increase as amperage
increases, however, low amperage cuts will
require less air pressure for a more stable cut.
d. Generally start with a mid-range
amperage setting (32-33 amps)
and adjust up or down from there.
Increased amperage will increase cutting heat.
This is needed with thicker and harder metals.
However, increased amperage will
reduce Duty Cycle time. (See page10.)
e. Move the Torch more slowly for thicker and
harder metals, and more quickly for thin or soft
metals. Keep the Torch moving while cutting.
Thicker Material
Thinner Material
Place the Plasma Cutter on a sturdy, level surface
at least six feet from the work area.
Allow at least 18" around all sides of
the Plasma Cutter for air flow.
ITEM 62204
Setup
Keep clothing free of grease, oil, solvents,
or any flammable substances. Wear dry,
insulating gloves and protective clothing.

Wear an ANSI‑approved welding helmet featuring
at least a number 10 shade lens rating.
Leather leggings, fire resistant shoes or
boots should be worn when using this
product. Do not wear pants with cuffs, shirts
with open pockets, or any clothing that can
catch and hold molten metal or sparks.
2.
Put the workpiece on a sturdy metal work
table that is open below the cutting area.
Molten slag will be blown through the
workpiece, and must be able to fall away freely.
Mount the workpiece to be cut to the work table so
that the cutting debris falls to the concrete floor.

set air pressure. It does not
allow normal operation.
Troubleshooting (cont.)
IMPORTANT!
Be CERTAIN to shut off the Plasma Cutter, and disconnect it from power and air before adjusting, cleaning,
or repairing the unit. A technician should discharge all capacitors before performing any internal procedures.
Safety
ARC IGNITES FOR SEVERAL SECONDS BUT THEN GOES OUT
Air pressure too high or too low.
Check the air pressure setting on
both the Compressor and the Cutter.
AIR PRESSURE
TOO HIGH
Setup
Set Compressor's Air
Pressure Regulator
between 90 - 120 PSI.
AIR PRESSURE
CORRECT
Check that the grounding point and the
metal being cut are both clean, dry, and
free from paint, oil, or dirt.
These sections need to conduct
electricity efficiently.
AIR PRESSURE
TOO LOW
a.Verify that the compressor is
delivering 4.5 CFM @ 80 PSI.
b.Set Cutter's Air
Pressure Regulator
between 60 - 80 PSI.
c.Verify air flow by
performing "Test Air
Flow:" on page 7.
DIRTY OR
COATED METAL
METAL IS CLEAN IN
BOTH AREAS
Operation
Use a wire wheel brush or sander
(not included) to thoroughly
clean both the grounding point
and the area that will be cut.
If any cleaners are used, allow them
to dry thoroughly before continuing.

Troubleshooting (cont.)
IMPORTANT!
Material being cut is too thick.
See Maximum Cutting Thickness on page 5.
WITHIN THICKNESS
RANGE
TOO THICK
Turn up the Output Current
Knob and try again at a
slower Torch travel speed.
Use a more
powerful
PlasmaCutter.
PROBLEM
CORRECTED
PROBLEM PERSISTS AT
MAXIMUM CURRENT SETTING
Air pressure too low.
Set Cutter's Air Pressure
Regulator between 60 - 80 PSI.
Take note of the
setting required for
this metal thickness.
AIR PRESSURE
CORRECT
AIR PRESSURE
TOO LOW
Disassemble Torch, inspect and replace
worn components, then reassemble Torch
tightly according to number 2 on page 10.
a. Verify that the
compressor is delivering
4.5 CFM @ 80 PSI.
Operation
CUT GOES ONLY PARTIALLY THROUGH THE WORKPIECE
Setup
Safety
Be CERTAIN to shut off the Plasma Cutter, and disconnect it from power and air before adjusting, cleaning,
or repairing the unit. A technician should discharge all capacitors before performing any internal procedures.
TORCH IN GOOD
CONDITION
DAMAGED
COMPONENTS FOUND
Cut at a slower pace, the arc
may not have enough time to
cut through the workpiece.
Maximum cutting speeds:
Disassemble Torch, inspect and
replace worn components, then
reassemble Torch tightly according
to number 2 on page 10.
3/8" Mild Steel @ 10 IPM (Rated)

Troubleshooting (cont.)
IMPORTANT!
Be CERTAIN to shut off the Plasma Cutter, and disconnect it from power and air before adjusting, cleaning,
or repairing the unit. A technician should discharge all capacitors before performing any internal procedures.
Safety
FAST CUTTING TIP WEAR OR EXCESSIVE SLAG FORMATION
These two problems have similar causes
and will often appear simultaneously.
The same diagnostic procedures
and remedies apply to both.
Setup
Current set too high;
cut at lowest setting possible
for the metal being cut.
PROBLEMS
REDUCED
PROBLEMS PERSIST AT
LOWEST PRACTICAL SETTING
Take into account the thickness
and type of metal to be cut
before starting. Thinner materials
require lower amp settings.
Operation
TORCH IN GOOD
CONDITION
Disassemble and inspect
Torch according to
number 2 on page 10.
DAMAGED
COMPONENTS FOUND
Air supply pressure may be inadequate:
a. Verify that the compressor is
delivering 4.5 CFM @ 80 PSI.
Replace worn components, then
reassemble Torch tightly according
to number 2 on page 10.
b. Set Cutter's Air Pressure Regulator between 60 - 80 PSI.
Maintenance
Additional factors:
a.Maintain a 1/16" distance from workpiece at all times.
b.Move Torch at proper rate. Maximum cutting speeds:
3/8" Mild Steel @ 10 IPM (Rated)
5/8" Mild Steel @ 5 IPM (Severence)
c. Compare workpiece thickness
to Maximum Cutting Thickness on page 5.

and warrants to the original purchaser that this product is free from defects in materials and workmanship for the
period of 90 days from the date of purchase. This warranty does not apply to damage due directly or indirectly,
to misuse, abuse, negligence or accidents, repairs or alterations outside our facilities, criminal activity, improper
installation, normal wear and tear, or to lack of maintenance. We shall in no event be liable for death, injuries
to persons or property, or for incidental, contingent, special or consequential damages arising from the use of

return repaired products at our expense, but if we determine there is no defect, or that the defect resulted
