SECTION 1:
GENERAL INFORMATION
1.01 Notes, Cautions and Warnings
Throughout this manual, notes, cautions, and warnings are used to
highlight important information. These highlights are categorized
as follows:
NOTE
An operation, procedure, or background information
which requires additional emphasis or is helpful in
efficient operation of the system.
CAUTION
A procedure which, if not properly followed, may cause
damage to the equipment.
!
WARNING
A procedure which, if not properly followed, may
cause injury to the operator or others in the operat-
ing area.
1.02 Important Safety Precautions
!
WARNING
OPERATION AND MAINTENANCE OF PLASMA ARC
EQUIPMENT CAN BE DANGEROUS AND HAZARDOUS
TO YOUR HEALTH.
Plasma arc cutting produces intense electric and
magnetic emissions that may interfere with the proper
function of cardiac pacemakers, hearing aids, or other
electronic health equipment. Persons who work near
plasma arc cutting applications should consult their
medical health professional and the manufacturer of
the health equipment to determine whether a hazard
exists.
To prevent possible injury, read, understand and fol-
low all warnings, safety precautions and instructions
before using the equipment. Call 1-603-298-5711 or
your local distributor if you have any questions.
GASES AND FUMES
Gases and fumes produced during the plasma cutting process can
be dangerous and hazardous to your health.
• Keep all fumes and gases from the breathing area. Keep your
head out of the welding fume plume.
• Use an air-supplied respirator if ventilation is not adequate
to remove all fumes and gases.
• The kinds of fumes and gases from the plasma arc depend on
the kind of metal being used, coatings on the metal, and the
different processes. You must be very careful when cutting
or welding any metals which may contain one or more of the
following:
Antimony Chromium Mercury
Arsenic Cobalt Nickel
Barium Copper Selenium
Beryllium Lead Silver
Cadmium Manganese Vanadium
• Always read the Material Safety Data Sheets (MSDS) that
should be supplied with the material you are using. These
MSDSs will give you the information regarding the kind and
amount of fumes and gases that may be dangerous to your
health.
• For information on how to test for fumes and gases in your
workplace, refer to item 1 in Subsection 1.03, Publications
in this manual.
• Use special equipment, such as water or down draft cutting
tables, to capture fumes and gases.
• Do not use the plasma torch in an area where combustible
or explosive gases or materials are located.
• Phosgene, a toxic gas, is generated from the vapors of chlo-
rinated solvents and cleansers. Remove all sources of these
vapors.
• This product, when used for welding or cutting, produces
fumes or gases which contain chemicals known to the State
of California to cause birth defects and, in some cases, cancer.
(California Health & Safety Code Sec. 25249.5 et seq.)
ELECTRIC SHOCK
Electric Shock can injure or kill. The plasma arc process uses
and produces high voltage electrical energy. This electric energy
can cause severe or fatal shock to the operator or others in the
workplace.
• Never touch any parts that are electrically “live” or “hot.”
• Wear dry gloves and clothing. Insulate yourself from the
work piece or other parts of the welding circuit.
• Repair or replace all worn or damaged parts.
• Extra care must be taken when the workplace is moist or
damp.
• Install and maintain equipment according to NEC code, refer
to item 9 in Subsection 1.03, Publications.
• Disconnect power source before performing any service or
repairs.
• Read and follow all the instructions in the Operating Manu-
al.
FIRE AND EXPLOSION
Fire and explosion can be caused by hot slag, sparks, or the plasma
arc.
• Be sure there is no combustible or flammable material in the
workplace. Any material that cannot be removed must be
protected.
• Ventilate all flammable or explosive vapors from the work-
place.
• Do not cut or weld on containers that may have held com-
bustibles.
• Provide a fire watch when working in an area where fire
hazards may exist.
• Hydrogen gas may be formed and trapped under aluminum
workpieces when they are cut underwater or while using a
water table. DO NOT cut aluminum alloys underwater or on
a water table unless the hydrogen gas can be eliminated or
dissipated. Trapped hydrogen gas that is ignited will cause
an explosion.

GENERAL INFORMATON 1-2 June 30, 2009
NOISE
Noise can cause permanent hearing loss. Plasma arc processes can
cause noise levels to exceed safe limits. You must protect your ears
from loud noise to prevent permanent loss of hearing.
• To protect your hearing from loud noise, wear protective
ear plugs and/or ear muffs. Protect others in the work-
place.
• Noise levels should be measured to be sure the decibels
(sound) do not exceed safe levels.
• For information on how to test for noise, see item 1 in Sub-
section 1.03, Publications, in this manual.
PLASMA ARC RAYS
Plasma Arc Rays can injure your eyes and burn your skin. The
plasma arc process produces very bright ultra violet and infrared
light. These arc rays will damage your eyes and burn your skin if
you are not properly protected.
• To protect your eyes, always wear a welding helmet or shield.
Also always wear safety glasses with side shields, goggles
or other protective eye wear.
• Wear welding gloves and suitable clothing to protect your
skin from the arc rays and sparks.
• Keep helmet and safety glasses in good condition. Replace
lenses when cracked, chipped or dirty.
• Protect others in the work area from the arc rays. Use protec-
tive booths, screens or shields.
• Use the shade of lens as suggested in the following per
ANSI/ASC Z49.1:
Minimum Protective Suggested
Arc Current Shade No. Shade No.
Less Than 300* 8 9
300 - 400* 9 12
400 - 800* 10 14
*These values apply where the actual arc is
clearly seen. Experience has shown that lighter
filters may be used when the arc is hidden by
the workpiece.
LEAD WARNING
This product contains chemicals, including lead, or otherwise
produces chemicals known to the State of California to cause
cancer, birth defects and other reproductive harm. Wash hands after
handling. (California Health & Safety Code § 25249.5 et seq.)

Notes
1. Duty Cycle is the percentage of time the system can be operated without overheating. Duty cycle is re-
duced if primary input voltage (AC) is low or the DC voltage is higher than shown in this chart.
2. Air supply must be free of oil, moisture, and other contaminants. Excessive oil and moisture may cause
double-arcing, rapid tip wear, or even complete torch failure. Contaminants may cause poor cutting perfor-
mance and rapid electrode wear. Optional filters provide increased filtering capabilities.
NOTE
IEC Rating is determined as specified by the International Electro-Technical Commission. These specifi-
cations include calculating an output voltage based upon power supply rated current. To facilitate com-
parison between power supplies, all manufacturers use this output voltage to determine duty cycle.
TDC Rating is determined using an output voltage representative of actual output voltage during cut-
ting with a TDC torch. This voltage may be more or less than IEC voltage, depending upon choice of
torch, consumables, and actual cutting operation.

INTRODUCTION 2T-2 June 30, 2009
2T.03 Introduction to Plasma
A. Plasma Gas Flow
Plasma is a gas which has been heated to an
extremely high temperature and ionized so that it
becomes electrically conductive. The plasma arc
cutting and gouging processes use this plasma
to transfer an electrical arc to the workpiece. The
metal to be cut or removed is melted by the heat
of the arc and then blown away.
While the goal of plasma arc cutting is separation of
the material, plasma arc gouging is used to remove
metals to a controlled depth and width.
In a Plasma Cutting Torch a cool gas enters Zone
B, where a arc between the electrode and the torch
tip heats and ionizes the gas. The main cutting arc
then transfers to the workpiece through the column
of plasma gas in Zone C.
By forcing the plasma gas and electric arc through a
small orifice, the torch delivers a high concentration
of heat to a small area. The stiff, constricted plasma
arc is shown in Zone C. Direct current (DC) straight
polarity is used for plasma cutting, as shown in the
illustration.
Zone A channels a secondary gas that cools the
torch. This gas also assists the high velocity
plasma gas in blowing the molten metal out of the
cut allowing for a fast, slag - free cut.

B. Gas Distribution
The single gas used is internally split into plasma
and secondary gases.
The plasma gas flows into the torch through the
negative lead, through the starter cartridge, around
the electrode, and out through the tip orifice.
The secondary gas flows down around the outside
of the torch starter cartridge, and out between the
tip and shield cup around the plasma arc.
C. Main Cutting Arc
DC power is also used for the main cutting arc. The
negative output is connected to the torch electrode
through the torch lead. The positive output is con-
nected to the workpiece via the work cable.

When the power source input voltage is over or under the safe operating range, the alarm light will turn on, at the
same time the current output will be cut off.
If the power supply voltage continually goes beyond the safe work voltage range it will shorten the power source
life-span.
3.04 Air Supply Connections
A. Connecting Air Supply to Unit
The connection is the same for compressed air or industrial compressed air in gas cylinders.
1. Connect the gas line to the compressed air input inlet port at the appropriate pressure. The illustration shows
typical fittings as an example.
NOTE
For a secure seal, apply thread sealant to the fitting threads, according to manufacturer's instructions.
Do Not use Teflon tape as a thread sealer, as small particles of the tape may break off and block the
small gas passages in the torch.

B. Using Industrial Compressed Air In Gas Cylinders
When using Industrial compressed air in gas cylinders as the gas supply:
1. Refer to the manufacturer’s specifications for installation and maintenance procedures for high pressure gas
regulators.
2. Examine the cylinder valves to be sure they are clean and free of oil, grease or any foreign material. Briefly
open each cylinder valve to blow out any dust which may be present.
3. The cylinder must be equipped with an adjustable high - pressure regulator capable of outlet pressures up to
100 psi (6.9 bar) maximum and flows of at least 300 scfh (141.5 lpm).
4. Connect gas supply hose to the cylinder.
NOTE
Pressure should be set at 100 psi (6.9 bar) at the high pressure gas cylinder regulator.
Supply hose must be at least 1/4 inch (6 mm) I.D.
For a secure seal, apply thread sealant to the fitting threads, according to manufacturer's instructions.
Do Not use Teflon tape as a thread sealer, as small particles of the tape may break off and block the
small gas passages in the torch.
