1.02 Important Safety Precautions
WARNINGS
OPERATION AND MAINTENANCE OF
PLASMA ARC EQUIPMENT CAN BE DANGEROUS AND HAZARDOUS TO YOUR
HEAL TH.
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
follow all warnings, safety precautions and instructions before using the equipment. Call 1-603298-5711 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 pr ocesses. Y ou 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 chlorinated 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.”
Date: January 27, 2004 1-1 GENERAL INFORMATION
• 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 Manual.
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 workplace.
• Do not cut or weld on containers that may have
held combustibles.
• 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. T rapped hydrogen gas that is ignited will
cause an explosion.
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 fr om loud noise, wear protective ear plugs and/or ear muffs. Protect others
in the workplace.
• 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 Subsection 1.03, Publications, in this manual.
PLASMA ARC RA YS
Plasma Arc Rays can injure your eyes and burn your skin.
The plasma arc process produces very bright ultra violet
and infra red light. These arc rays will damage your
eyes and burn your skin if you are not properly pr otected.
• 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 protective 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.

INTRODUCTION
2.03 Specifications & Design Features
NOTE
2.01 Scope of Manual
This manual contains descriptions, operating instructions and
maintenance procedures for the PCH/M-102 T or ch using the
SureLok electrode design. Service of this equipment is restricted
to properly trained personnel; unqualified personnel are strictly
cautioned against attempting repairs or adjustments not covered in this manual, at the risk of voiding the W arranty .
Read this manual thoroughly . A complete understanding of the
characteristics and capabilities of this equipment will assure
the dependable operation for which it was designed.
2.02 General Description
NOTE
Refer to Section 2.05, Introduction To Plasma, for
a more detailed description on plasma theory.
The T orch provides cutting capacity of up to 1 inch (25.4 mm) at
100 amperes. In the torch, a single torch lead provides compressed air from a single source to be used as both the plasma
and secondary gas. The air flow is divided inside the torch
head. Single-gas operation provides a smaller sized torch and
inexpensive operation.
Plasma torches are similar in design to the common automotive
spark plug. They consist of negative and positive sections
which are separated by a center insulator . Inside the torch, the
pilot arc is initiated in the gap between the negatively charged
electrode and the positively charged tip. Once the pilot arc has
ionized the plasma gas, the superheated column of gas flows
through the small orifice in the torch tip, which is focused on
the metal to be cut.
Refer to Appendix Pages for additional specifications as related to the Power Supply used.

H. Direct Contact Hazard
For exposed tip the recommended standoff is 1/8 3/8 inch or 3 - 9.5 mm.
A. Plasma Gas Flow
Plasma is defined as 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 process 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
(refer to Figure 2-2), where a pilot 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.

D. Capacitive Discharge

er
Because direct current (DC) alone is not sufficient to strike
and maintain the pilot arc, capacitive discharge is also used.
The high voltage jumps between the tip and electrode with
the DC following.

Figure 2-2 Typical Torch Head Detail
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 (Figure 2-2). Direct current (DC) straight polarity is
used for plasma cutting, as shown in the illustration.
Zone A (Figure 2-2) is used as a secondary gas that cools
the torch. This gas 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.
A-00002
B
E. Main Cutting Arc
DC power is also used for the main cutting arc. The negative output is connected to the torch electrode through the
A
torch lead. The positive output is connected to the workpiece via the work cable and to the torch through a pilot
wire.
F. Interlocks
One pressure switch acts as an interlock for the gas supply . If supply pressure falls below minimum requirements
the pressure switch will open, shutting of f the DC power,
and the GAS indicator will go off. When adequate gas
supply pressure is available the pressure switch will close,
allowing power to be resumed for cutting.
G. Parts-In-Place (PIP)
The torch head has built-in contacts called Parts-In-Place
(PIP). These two contacts are made through the canted
coiled spring inside the shield cup when it is installed. The
torch will fail to operate if these contacts are not made.
