the plasma stays in contact with the metal that
is being cut. In order to ensure this contact,
protect the cut from oxidation, and regulate
the unpredictable nature of plasma, the cut-
ter nozzle has a second set of channels. These
channels release a constant flow of shielding
gas around the cutting area. The pressure of
this gas flow effectively controls the radius of
the plasma beam.
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
galaxies are made of plasma. On Earth, you
will find plasma in lightening and a few other
places. Neon tubes and florescent lights con-
tain 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
molecules of water away from each other to
change the water is in. At very high tempera-
ture and pressure the water molecules them-
selves break apart, and the atoms begin to ion-
ize. Normal atoms 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 electri-
cal outlet before performing any inspection,
maintenance, 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
E N G L I S H •
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 dam-
aged equipment.
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
before cutting.
5. If the unit repeatedly shuts down from ther-
mal overload, stop all use. Have the Air Plasma
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
electronic repairs. Any repairs must be com-
pleted 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 follow-
ing 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 connec-
tion.
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 techni-
cian should discharge all capacitors before per-
forming and internal procedures.
