the tip of the nozzle contacts the work metal,
the connection creates a circuit. When the
nozzle is lifted away, the arc will continue. As
the inert gas passes through the channel, the
arc heats the gas until it becomes ionized.
This reaction creates a stream of directed
plasma, approximately 30,000° F (16,649° C)
and moving at approximately 20,000 feet per
second (6,096 m/sec), that reduces metal to
molten slag.
The plasma itself conducts electrical
current. The cycle of creating the arc is
continuous as long as power is supplied to the
electrode and 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 cutter 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.
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,
maintenance, or cleaning procedures.
1. Before each use,

4. Verify that the cooling fan is operational
before cutting.
5. If the unit repeatedly shuts down from
thermal 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 components. Refer to the
assembly drawing on page 16.
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 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. The fan does not work properly.
d. Any switch or control does not work
properly.
e. Any damage to cables.
