1-2. Plasma Arc Cutting Hazards
WARNING
The symbols shown below are used throughout this manual to call attention to and identify possible
hazards. When you see the symbol, watch out, and follow the related instructions to avoid the hazard. The
safety information given below is only a summary of the more complete safety information found in the
Safety Standards listed in Section 1-4. Read and follow all Safety Standards.
Only qualified persons should install, operate, maintain, and repair this unit.
During operation, keep everybody, especially children, away.
CUTTING can cause fire or explosion.
Hot metal and sparks blow out from the cutting arc.
The flying sparks and hot metal, hot workpiece, and
hot equipment can cause fires and burns. Check
and be sure the area is safe before doing any cutting.
1. Protect yourself and others from flying sparks and hot metal.
2. Do not cut where flying sparks can strike flammable material.
3. Remove all flammables within 35 ft (10.7 m) of the cutting arc. If
this is not possible, tightly cover them with approved covers.
4. Be alert that sparks and hot materials from cutting can easily go
through small cracks and openings to adjacent areas.
5. Watch for fire, and keep a fire extinguisher nearby.
6. Be aware that cutting on a ceiling, floor, bulkhead, or partition can
cause fire on the hidden side.
7. Do not cut on closed containers such as tanks or drums.
8. Connect work cable to the work as close to the cutting area as
practical to prevent cutting current from traveling long, possibly
unknown paths and causing electric shock and fire hazards.
9. Never cut containers with potentially flammable materials inside
− they must be emptied and properly cleaned first.
10. Do not cut in atmospheres containing explosive dust or vapors.
11. Do not cut pressurized cylinders, pipes, or vessels.
12. Do not cut containers that have held combustibles.
13. Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
14. Do not locate unit on or over combustible surfaces.
15. Remove any combustibles, such as a butane lighter or matches,
from your person before doing any cutting.
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks
or severe burns. The torch and work circuit is
electrically live whenever the output is on. The input
power circuit and machine internal circuits are also
live when power is on. Plasma arc cutting requires
the arc (200 to 400 volts dc are common), but also uses torches
designed with safety interlock systems which turn off the machine
when the shield cup is loosened or if tip touches electrode inside the
nozzle. Incorrectly installed or improperly grounded equipment is a
hazard.
1. Do not touch live electrical parts.
2. Wear dry, hole-free insulating gloves and body protection.
3. Insulate yourself from work and ground using dry insulating mats
or covers big enough to prevent any physical contact with the
work or ground.
4. Do not touch torch parts if in contact with the work or ground.
5. Turn off power before checking, cleaning, or changing torch
parts.
6. Disconnect input power before installing or servicing this
equipment. Lockout/tagout input power according to OSHA CFR
1910.147 (see Safety Standards).
7. Properly install and ground this equipment according to its
Owner’s Manual and national, state, and local codes.
higher voltages than welding to start and maintain
FLYING SPARKS AND HOT METAL
can cause injury.
Sparks and hot metal blow out from the cutting arc.
Chipping and grinding cause flying metal.
8. Check and be sure that input power cord ground wire is properly
connected to ground terminal in disconnect box or that cord plug
is connected to a properly grounded receptacle outlet − always
verify the supply ground.
9. When making input connections, attach proper grounding
conductor first.
10. Frequently inspect input power cord for damage or bare wiring −
replace cord immediately if damaged − bare wiring can kill.
11. Turn off all equipment when not in use.
12. Inspect and replace any worn or damaged torch cable leads.
13. Do not wrap torch cable around your body.
14. Ground the workpiece to a good electrical (earth) ground if
required by codes.
15. Use only well-maintained equipment. Repair or replace damaged
parts at once.
16. Wear a safety harness if working above floor level.
17. Keep all panels and covers securely in place.
18. Do not bypass or try to defeat the safety interlock systems.
19. Use only torch(es) specified in Owner’s Manual.
20. Keep away from torch tip and pilot arc when trigger is pressed.
21. Clamp work cable with good metal-to-metal contact to workpiece
(not piece that will fall away) or worktable as near the cut as
practical.
1. Wear approved face shield or safety goggles with side shields.
2. Wear proper body protection to protect skin.
3. Wear flame-resistant ear plugs or ear muffs to prevent sparks
from entering ears.
OM-181 460 Page 1
Page 4
ARC RAYS can burn eyes and skin.
Arc rays from the cutting process produce intense
visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin.
1. Wear face protection (helmet or shield) with correct shade of filter
to protect your face and eyes when cutting or watching. ANSI
Z49.1 (see Safety Standards) suggests a No. 9 shade (with No. 8
as minimum) for all cutting currents less than 300 amperes. Z49.1
adds that lighter filter shades may be used when the arc is hidden
by the workpiece. As this is normally the case with low current
cutting, the shades suggested in Table 1 are provided for the
operator’s convenience.
2. Wear approved safety glasses with side shields.
3. Use protective screens or barriers to protect others from flash
and glare; warn others not to watch the arc.
4. Wear protective clothing made from durable, flame-resistant
material (wool and leather) and foot protection.
NOISE can damage hearing.
Prolonged noise from some cutting applications can
damage hearing if levels exceed limits specified by
OSHA (see Safety Standards).
5. Use approved ear plugs or ear muffs if noise level is high.
6. Warn others nearby about noise hazard.

FUMES AND GASES can be
hazardous to your health.
Cutting produces fumes and gases. Breathing these
fumes and gases can be hazardous to your health.
1. Keep your head out of the fumes. Do not breathe the fumes.
2. If inside, ventilate the area and/or use exhaust at the arc to
remove cutting fumes and gases.
3. If ventilation is poor, use an approved air-supplied respirator.
4. Read the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instruction for metals to be cut, coatings, and
cleaners.
PLASMA ARC can cause injury.
The heat from the plasma arc can cause serious
burns. The force of the arc adds greatly to the burn
hazard. The intensely hot and powerful arc can
quickly cut through gloves and tissue.
1. Keep away from the torch tip.
2. Do not grip material near the cutting path.
CYLINDERS can explode if damaged.
Gas cylinders contain gas under high pressure. If
damaged, a cylinder can explode. Since gas
cylinders are normally part of metalworking
processes, be sure to treat them carefully.
1. Protect compressed gas cylinders from excessive heat,
mechanical shocks, slag, open flame, sparks, and arcs.
2. Install and secure cylinders in an upright position by chaining
them to a stationary support or equipment cylinder rack to
prevent falling or tipping.
3. Keep cylinders away from any cutting or other electrical circuits.
5. Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Fumes from cutting and
oxygen depletion can alter air quality causing injury or death. Be
sure the breathing air is safe.
6. Do not cut in locations near degreasing, cleaning, or spraying
operations. The heat and rays of the arc can react with vapors to
form highly toxic and irritating gases.
7. Do not cut on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the
cutting area, the area is well ventilated, and if necessary, while
wearing an air-supplied respirator. The coatings and any metals
containing these elements can give off toxic fumes when cut.
8. Do not cut containers with toxic or reactive materials inside or
containers that have held toxic or reactive materials − they must
be emptied and properly cleaned first.
3. The pilot arc can cause burns − keep away from torch tip when
trigger is pressed.
4. Wear proper flame-retardant clothing covering all exposed body
areas.
5. Point torch away from your body and toward work when pressing
the torch trigger − pilot arc comes on immediately.
6. Turn off power source and disconnect input power before
disassembling torch or changing torch parts.
7. Use only torch(es) specified in the Owner’s Manual.
4. Never allow electrical contact between a plasma arc torch and a
cylinder.
5. Never cut on a pressurized cylinder − explosion will result.
6. Use only correct gas cylinders, regulators, hoses, and fittings
designed for the specific application; maintain them and
associated parts in good condition.
7. Turn face away from valve outlet when opening cylinder valve.
8. Keep protective cap in place over valve except when cylinder is in
use or connected for use.
9. Read and follow instructions on compressed gas cylinders,
associated equipment, and CGA publication P-1 listed in Safety
Standards.
1-3. Additional Installation, Operation, And Maintenance Hazards
HOT PARTS can cause severe burns.
1. Do not touch hot parts bare handed.
2. Allow cooling period before working on torch.
FLYING PIECES OF METAL or DIRT can
injure eyes.
1. Wear safety glasses with side shields or face
shield.
OM-181 460 Page 2
FALLING EQUIPMENT can cause
serious personal injury and equipment
damage.
1. Use lifting eye to lift unit only, NOT running gear,
gas cylinders, or any other accessories.
2. Use equipment of adequate capacity to lift unit.
3. If using lift forks to move unit, be sure forks are long
enough to extend beyond opposite side of unit.
Page 5
FIRE OR EXPLOSION can result from
placing unit on, over, or near
combustible surfaces.
1. Do not locate unit on, over, or near combustible
surfaces.
2. Do not install unit near flammables.
MOVING PARTS can cause injury.
1. Keep away from moving parts such as fans.
2. Keep all doors, panels, covers, and guards closed
and securely in place.
STATIC ELECTRICITY can damage
parts on circuit boards.
1. Put on grounded wrist strap BEFORE handling
boards or parts.
2. Use proper static-proof bags and boxes to store,
move, or ship PC boards.
OVERUSE can cause OVERHEATED
EQUIPMENT.
1. Allow cooling period.
2. Reduce amperage (thickness) or reduce duty
cycle before starting to cut again.
3. Follow rated duty cycle.
HIGH-FREQUENCY RADIATION can
interfere with radio navigation, safety
services, computers, and
communications equipment.
1. Have only qualified persons familiar with electronic
equipment perform this installation.
2. The user is responsible for having a qualified
electrician promptly correct any interference
problem resulting from the installation.
3. If notified by the FCC about interference, stop using
the equipment at once.
4. Have the installation regularly checked and
maintained.
5. Keep high-frequency source doors and panels
tightly shut, keep spark gaps at correct setting, and
use grounding and shielding to minimize the
possibility of interference.
MAGNETIC FIELDS FROM HIGH
CURRENTS can affect pacemaker
operation.
1. Pacemaker wearers keep away.
2. Wearers should consult their doctor before going
near plasma arc cutting operations.
SIGNIFICANT DC VOLTAGE exists after
removal of input power on inverters.
1. Turn Off inverter, disconnect input power, and
discharge input capacitors according to
instructions in Maintenance Section before
touching any parts.

Considerations About Welding And The Effects Of Low Frequency
Electric And Magnetic Fields
The following is a quotation from the General Conclusions Section of
the U.S. Congress, Office of Technology Assessment, Biological
Effects of Power Frequency Electric & Magnetic Fields − Background
Paper, OTA-BP-E-53 (Washington, DC: U.S. Government Printing
Office, May 1989): “. . . there is now a very large volume of scientific
findings based on experiments at the cellular level and from studies
with animals and people which clearly establish that low frequency
magnetic fields can interact with, and produce changes in, biological
systems. While most of this work is of very high quality, the results are
complex. Current scientific understanding does not yet allow us to
interpret the evidence in a single coherent framework. Even more
frustrating, it does not yet allow us to draw definite conclusions about
questions of possible risk or to offer clear science-based advice on
strategies to minimize or avoid potential risks.”

5-4. Checking/Replacing Retaining Cup, Tip, And Electrode
Overtightening will strip threads. Do not overtighten electrode, tip, and retaining cup during assembly. Do not cross-thread parts causing stripping. Use care during torch assembly and parts
replacement.
Inspect shield cup, tip, and electrode for wear before cutting or whenever cutting speed has been
significantly reduced. Do not operate torch without a tip or electrode in place. Be sure to use genuine replacement parts.
A good practice is to replace both the tip and electrode at the same time.
Turn Off power source, and remove input power plug
from receptacle before checking torch parts.

Make sure this area is
clean of any debris.
The word “front” on
swirl ring must face
away from torch body.
Make sure swirl ring is
clean of any debris and
no holes are obstructed.
