WHAT IS PLASMA?
Materials in Nature exist in one of four differ-
ent states: Solid, Liquid, Gas or Plasma. Plasma
is very rare on Earth because of its very high
temperature; however most of the matter in
the universe is plasma. The Sun, stars and galax-
ies are made of plasma. On Earth, you will find
plasma in lightening and a few other places.
Neon tubes and florescent lights contain low-
temperature plasma when lighted.
The difference between water ice, liquid water
and water vapor is temperature. In each of these
states, temperature energy pushes the mol-
ecules of water away from each other to change
the water is in. At very high temperature and
pressure the water molecules themselves break
apart, and the atoms begin to ionize. Normal at-
oms are made up of protons and neutrons in the
nucleus, surrounded by a cloud of electrons. In
plasma, the electrons separate from the nucleus.
The electrons are negatively charged, and they
leave behind their positively charged nuclei
which are known as ions. When the fast-moving
electrons collide with other electrons and ions,
they release vast amounts of energy. This energy
is what gives plasma its unusual status and great
cutting power.
MAINTENANCE
WARNING: Make sure the Power Switch of
the Plasma Cutter is in its "OFF" position and
that the tool is unplugged from the electrical
outlet before performing any inspection, main-
tenance, or cleaning procedures.
1. Before each use, inspect the general condi-
tion of the Air Plasma Cutter. Check for loose
cable connections, misalignment or binding
of the fan, cracked or broken parts, damaged
electrical wiring, and any other condition that
may affect its safe operation. If abnormal noise
or vibration occurs, have the problem corrected
before further use. Do not use damaged equip-
ment.
2. Periodically recheck all nuts, bolts, and screws
for tightness.
3. Periodically blow the dust from the cooling
vents with compressed air.
4. Verify that the cooling fan is operational be-
fore cutting.
5. If the unit repeatedly shuts down from ther-
mal overload, stop all use. Have the Air Plasma
18
Cutter inspected and repaired by a qualified
service technician.
6. Store the welder and accessories in a clean
and dry location.
7. Periodically disassemble and clean the Torch
Head components with steel wool. Replace
burnt, cracked, distorted, or coated compo-
nents.
8. To gain access to the internal components of
the unit, remove screws from Main Body Cover.
The home user is strongly advised not to remove
the tool covers and not to attempt any elec-
tronic repairs. Any repairs must be completed
by a qualified technician. Opening the tool will
void any warranties, and may result in damage
to equipment or possible personal injury. Don't
do it.
9. On a daily basis check for any of the following
problems: If any are found, take the tool to a
qualified repair technician.
a. Abnormal vibration, sound or smell.
b. Abnormal heating at any cable connection.
c. Then fan does not work properly.
d. Any switch or control does not work prop-
erly.
e. Any damage to cables.
TROUBLESHOOTING
Be CERTAIN to shut off the Plasma Cutter, and
disconnect it from power and air before adjust-
ing, cleaning, or repairing the unit. A technician
should discharge all capacitors before perform-
ing and internal procedures.
FAN RUN WHEN SWITCHED ON BUT ARC
WILL NOT IGNITE
The Air pressure may be too high or too low.
Check the Air Pressure setting on the regulator's
gauge.
• Air pressure too high: Adjust the Air Regulator
to deliver only 60-80 PSI to the Cutter.
• Air pressure too low:
a. Verify that the compressor is delivering at
least 3.5 CFM @60 PSI to the tool
b. The Regulator on the unit must be set to at
least 60 PSI
• Air pressure correct: Make sure that all air and
electrical connections are tight.
· LOOSE CONNECTIONS: Shut off switch, if not
off already, and tighten connections. If con-
nections do not tighten properly, contact a
qualified technician.
