1. Protect your eyes from welding light by wearing a welder's
helmet fitted with a filter shade suitable for the type of
welding you are doing. The welding process produces
intense white light, infrared and ultraviolet light, these arc
rays can burn both eyes and skin.
1.1. Consult the Welding Shade Guide in Appendix A for
the minimum shade to protect the eyes based on the
amperage and type of welding.
2. An opaque helmet will protect against the ultraviolet or
infrared light. A helmet will also protect against ejected hot
material and slag. The helmet should protect the face,
forehead, ears and neck.
3. Wear a fire-resistant head covering like a skull cap or
balaclava hood to protect your head when the faceplate is
down or when using a welding hand-held face shield.
4. Wear ventilated safety goggles beneath the welding helmet
or behind the hand-held face shield. The cooling weld bead
may fragment or eject slag that can damage the eyes,
when the helmet or hand-held face shield is not in place.
4.1 Eye protection equipment should comply with CSA
Z94.3-07 or ANSI Z87.1 standards based on the type of
work performed.
5. Wear fire resistant ear plugs when welding overhead to
prevent spatter or slag from falling into ear.
PROTECTIVE CLOTHING
1. Wear a leather apron or jacket, leather welding gloves and full
foot protection. Choose clothing fabrics that resist sparks,
heat, flames and splashes of molten material. Artificial fabrics
may burn and melt, resulting in a more severe injury.
1.1 Wear welding capes and sleeves when performing
overhead welding.

sufficient to remove welding fumes or when there is risk of
oxygen deficiency.
1.1. Wear a NIOSH approved respirator when working on
materials that produce dust or particulate matter.
2. Work in a confined space only if it is well ventilated or while
wearing an air-supplied respirator. Welding fumes and
gases can displace air and lower the oxygen level causing
injury or death. Be sure the breathing air is safe (See Fumes
and Gases).
3. The user can take the additional precaution of informing
another person in the work area of the potential danger, so
that person can watch for indications that the user is

1. Use the correct tool for the job. This tool was designed for
a specific function. Do not modify or alter this tool or use it
for an unintended purpose.
2. Protect against reflected arc rays. The rays can reflect off a
shiny surfaces behind the user, into the helmet and off the
filter lens into the eyes. Remove or cover any reflective
surface behind the user such as a glossy painted surface,
aluminum, stainless steel or glass.
3. Welding produces sparks and molten slag. A cooling bead
can eject chips or fragments of slag. Any of these can
cause direct harm to the eyes or skin of the user or
bystanders.
4. Erect protective screens or barriers to protect bystanders
from the flash and glare; warn others in the area not to
watch the arc. Do not strike a welding arc until all
bystanders and you (the user) have welding shields and/or
helmets in place.
5. Immediately replace a cracked or broken helmet or a
scratched or damaged lens filter to avoid damage to the
eyes or face from arc flash or ejected molten material.
6. Do not allow the plasma torch to accidentally touch the
ground clamp or grounded work. An arc flash will result from
contact and can injury the unprepared user and bystanders.
It can also damage the plasma cutting machine.
7. Do not handle hot metal or electrode stubs with bare
hands. Handling may result in a burn injury.
8. Do not use the plasma cutting machine if personal
movement is confined or if there is a danger of falling.
9. Keep all panels and covers securely in place when
operating the plasma cutting machine.
10. Insulate the ground clamp when not connected to a
workpiece to prevent contact with any metal object.

11. Do not operate the plasma cutting machine if the plasma
torch or welding cable is wet. Do not immerse them in
water. These components and the plasma cutting machine
must be completely dry before attempting to use them.
12. Do not point the plasma torch at any body part of yourself
or at anyone else.
13. Do not use a plasma cutting machine to thaw frozen pipes.
14. Insulate yourself from the work and the ground using dry
insulation. Make certain that the insulation is large enough
to cover your full area of physical contact.
15. Never dip the electrode in water for cooling.
16. When not welding, make certain that no part of the electrode
circuit is touching the workpiece or the ground. Accidental
contact can cause overheating and create a fire hazard.
17. Maintain good ventilation of the louvers on this equipment.
Good ventilation is of critical importance for the normal
performance and service life of this equipment.
FIRE AND EXPLOSION PRECAUTIONS
Arc welding can produce sparks, hot slag or spatter, molten
metal drops and hot metal parts that can start fires.
1. Clear the floor and walls of an area of all combustible and/or
flammable materials up to 39 ft (12 metres) away from the
plasma cutting machine. Hot debris ejected during welding
can land at a considerable distance away. Solid floors of
concrete or masonry is the preferred working surface.
1.1 Cover any combustible material with fire resistant
covers or shields, if it cannot be removed. The covering
must be tight and should not leave openings for sparks
or ejected slag to enter.
1.2 Check both sides of a panel or wall for combustible
material. Remove the combustible material before welding.

8611303 PROCUT45 PLASMA CUTTER V1.1
10 For technical questions call 1-800-665-8685
2. A combustible floor should be protected with a fire
resistant covering.
3. Seal cracks and openings to adjacent areas that a spark or
slag can enter. Seal any openings found with a fire-resistant
cover. Shut doors and windows that do not provide
ventilation or erect protective screens in front of them
when possible.
4. Avoid welding near hydraulic lines or containers containing
flammable contents.
5. Do not perform any welding work on containers that held
flammable or toxic substance until they are cleaned by a
person trained in removing toxic and flammable substances
and vapours per the American Welding Standard AWS F4.1.
6. Open a container before performing any welding work on
it. The heat generated by the welding process will cause
the air and gases to expand. The internal pressure may
cause a sealed or closed container to rupture, possibly
causing an injury or death.
7. Do not weld pipes or metal that are covered in combustible
material or in contact with combustible structure such as a
wall. Only weld if the covering can be safely removed.
7.1 Follow all safety precautions and legal requirements
before welding a workpiece that contains asbestos or
attempting to remove the asbestos covering. This
requires expert knowledge and equipment.
7.2 Molten slag can run down the inside and outside of a
pipe and start a fire. Be aware where the pipe
terminates and take precautions.
8. Do not weld a panel that is a sandwich construction of
combustible and metal materials.
9. Have a fire extinguisher available for immediate use. A dry
chemical fire extinguisher for Types A, B and C is suggested.

V1.1 PROCUT45 PLASMA CUTTER 8611303
Visit www.princessauto.com for more information 11
9.1 Welding a combustible metal like zinc, magnesium or
titanium requires a Type D fire extinguisher.
9.2 Do not use liquid based fire extinguishing methods
near the electric arc plasma cutting machine, as it may
cause a shock hazard.
10. Ventilation systems should be positioned so sparks or
molten slag isn’t carried to an adjacent area.
11. Have a Fire Watcher observing areas outside of the
welder’s view, such as the opposite side of a wall or behind
the welder. A fire may also start on the other side of a
structure that could not be removed. The Fire Watcher will
extinguish a fire or raise the alarm to evacuate if the fire
cannot be contained by the extinguishing equipment.
11.1 A fire watch extends at least 30 minutes after the
welding is complete to ensure there are no fires caused
by smoldering sparks or ejected material.
FUMES AND GASES
WARNING! Stop welding and move to a location with
ventilation if your eyes, nose or throat become irritated. This
indicates the ventilation is not adequate to remove the fumes.
Do not resume welding or cutting until the ventilation is
improved and the discomfort ceases. Seek medical attention
if the symptoms do not diminish or if the welder experiences
nausea, dizziness or malaise.
Welding or cutting may produce hazardous fumes and gas during
the welding process. A well ventilated work area can normally
remove the fumes and gases, but sometimes the welding
produces fumes and gases that are hazardous to your health.
1. Only work in a confined space if the area is well ventilated
or while wearing a respirator or an air-supplied respirator.
Welding fumes and gases can displace air and lower the
oxygen level causing injury or death. Be sure the breathing
air is safe. Always have a trained watchperson nearby.

8611303 PROCUT45 PLASMA CUTTER V1.1
12 For technical questions call 1-800-665-8685
1.1 If ventilation in the work area is poor, use an approved
air-supplied respirator. All the people in the work area
must also have air-supplied respirators.
1.2 Oxygen displacement can occur in confined areas when
the shielding gas fills the area and pushes out air.
1.2.1 Argon, Propane and Carbon Dioxide are heavier
than air and will fill a confined space from the
bottom up.
1.2.2 Helium and Natural Gas are lighter than air and
will fill a confined space from the top down.
2. Avoid positions that allow welding fumes to reach your
face. Always attempt to weld ‘upwind’ of the workpiece
with the airflow across the face of the welder. Airflow from
behind may create a low pressure area in front of the
welder and draw the fumes to the person.
3. Ventilate the work area to remove welding fumes and
gases. The fumes and gases should be drawn away from
the user.
3.1 Ventilation should be enough to disperse fumes,
but not enough to disturb the shielding gas or flame
during welding.
3.2 Ventilation exhaust shall be directed to a non-work area
to avoid exposing other people to potential toxic or
dangerous fumes.
3.3 Air removed from the work area by the ventilation system
must be replenished with fresh air to avoid oxygen
starvation or a build-up of fumes or gases. Only use air to
provide ventilation. Any other combination of gases may
be explosive or toxic to people in the work area.
3.4 Ventilation methods that remove gas and fumes from
the welding point before they reach the welder’s face
should be given preference.

V1.1 PROCUT45 PLASMA CUTTER 8611303
Visit www.princessauto.com for more information 13
4. Avoid welding in a work area that has vapours from cleaning,
degreasing or any spraying operations. The heat and light
from welding can react with the vapour and form irritating or
potentially toxic gases. Wait for the vapours to disperse.
5. Consult the manufacturer's Safety Data Sheets (SDS) for
instructions and precautions about metals, consumables,
coatings, cleaners and degreasers.
5.1 Do not weld on coated metals such as galvanized, lead
or cadmium plated steel, unless the coating is removed
from the weld area. The coatings and any metals
containing these elements can give off toxic fumes
during the welding process.
5.2 Do not weld, cut or heat lead, zinc, cadmium, mercury,
beryllium or similar metals without seeking professional
advice and inspection of the welding area’s ventilation.
These metals produce extreme toxic fumes, which can
cause discomfort, illness and death.
5.3 Do not weld or cut near chlorinated solvents or in areas
that chlorinates solvents can enter. The heat or
ultraviolet light of the arc can separate chlorinated
hydrocarbons into a toxic gas (phosgene) that can
poison or suffocate the user or bystanders.
COMPRESSED GAS
CYLINDER PRECAUTIONS
WARNING! Improper handling or maintenance of compressed
gas cylinders and regulators can result in serious injury or
death. Do not use a cylinder or its contents for anything other
than its intended use.
1. Do not attempt to mix gases or refill a gas cylinder. Exchange
a cylinder or have it refilled by a professional service.
2. Do not deface or alter the name, number or other markings
on a cylinder. Do not rely on a cylinder’s colour to identify the

8611303 PROCUT45 PLASMA CUTTER V1.1
14 For technical questions call 1-800-665-8685
contents. Do not connect a regulator to a cylinder that
contains a gas that the regulator was not designed to handle.
3. Do not expose a cylinder to excessive heat, sparks, slag,
flame or any other heat source.
3.1 A cylinder exposed to temperatures above 130 °F will
require water spray cooling. This method may not be
compatible with the plasma cutting machine due to the
hazard of electrocution.
4. Do not expose a cylinder to electricity of any kind.
5. Do not attempt to lubricate a regulator. Always change a
cylinder carefully to prevent leaks and damage to the
cylinder’s walls, valve or safety devices.
6. Gases in the cylinder are under pressure. Protect the
cylinder from bumps, falls, falling objects and harsh
weather. A punctured cylinder under pressure can become
a lethal projectile. If a cylinder is punctured, do not
approach until all pressure is released.
6.1 Protect the valve and regulator. Damage to either can
result in regulator’s explosive ejection from the cylinder.
7. Always secure a gas cylinder in a vertical position to a
welding cart or other fixed support with a steel chain, so it
cannot be knocked over.
7.1 Away from areas where they may be struck or
subjected to physical damage.
7.2 A safe distance from the cutting operations and any
other source of heat, sparks or flame.
7.3 Do not use as an improvised support or roller.
8. Always place the cylinder cap securely on the cylinder
unless it is in use or being serviced.
9. Do not use a wrench or hammer to open a cylinder valve that
cannot be opened by hand. Notify your supplier for instructions.

V1.1 PROCUT45 PLASMA CUTTER 8611303

10. Do not modify or exchange gas cylinder fittings.
11. Close the cylinder valve and immediately remove the faulty
regulator from service for repair, if any of the following
conditions exist:
11.1 Gas leaks externally.
11.2 Delivery pressure continues to rise with the
downstream valve closed.
11.3 The gauge pointer does not move off the stop pin
when pressurized or fails to return to the stop pin
after pressure is released.
12. Do not attempt to make regulator repairs. Send faulty
regulators to the manufacturer's designated repair center.
13. Do not weld on the gas cylinder.
14. Keep your head and face away from the cylinder valve
outlet when opening the cylinder valve.
15. Compressed gas cylinders must not be located in a
confined space with the person welding to prevent the
possibility of leaks displacing the oxygen.
AIR TOOL PRECAUTIONS
1. Extended exposure to air tool noise may cause hearing loss.
Ear protection gear can reduce or eliminate the noise level.
2. Inspect the tool's air hose for cracks, fraying or other faults
before each use. Discontinue use if the air hose is damaged or
hissing is heard from the air hose or connectors, while
operating the tool. Replace the defective component/air hose.
3. Do not allow people, mobile equipment or vehicles to pass
over the unprotected air hose. Position the air hose away
from high traffic areas, in a reinforced conduit or place planks
on both sides of the air hose to create a protective trench.
4. Prevent damage to the air hose by observing the following:
4.1 Never carry the tool by the air hose.

8611303 PROCUT45 PLASMA CUTTER V1.1
16 For technical questions call 1-800-665-8685
4.2 Keep the air hose behind the tool and out of the tool's
work path.
4.3 Keep the air hose away from heat, oil, sharp edges or
moving parts.
4.4 Do not wrap the air hose around the tool as sharp
edges may pierce or crack the air hose. Coil the air
hose when storing.
5. A damaged or disconnected air hose under pressure may
whip around and inflict personal injury or damage the work
area. Secure the compressor's air hose to a fixed or
permanent structure with clamps or cable ties.
6. Install an in-line shutoff valve or regulator to allow
immediate control over the air supply in an emergency,
even if a hose is ruptured
7. Check the manufacturer’s maximum pressure rating for air
tools and accessories. Compressor outlet pressure must be
regulated so as to never exceed the maximum pressure rating
of the tool.
ELECTRICAL SAFETY
WARNING! To reduce risk of electric shock, be certain that the
plug is connected to a properly grounded receptacle.
1. Do not come into physical contact with the welding current
circuit. The welding current circuit includes:
1.1 The workpiece or any conductive material in contact with it.
1.2 The ground clamp.
1.3 The electrode.
1.4 Any metal parts on the plasma torch.
1.5 The output terminals.
2. Insulate yourself from the electrical current and ground
using electrical insulating mats or covers big enough to
prevent physical contact with the workpiece or ground.

V1.1 PROCUT45 PLASMA CUTTER 8611303
Visit www.princessauto.com for more information 17
3. Connect the ground clamp as close to the welding area on
the workpiece as practical to prevent welding current from
traveling along an unexpected path and causing an electric
shock or fire hazard.
3.1 An option is to attach the ground clamp to a bare
metal spot on a metal workbench. The circuit will
complete as long as the workpiece is also in full contact
with the bare metal workbench.
4. Do not weld on damp surfaces that can transmit the electric
current without taking precautions for the welder and
bystanders. The electrode and nozzle are electrically ‘hot’.
5. Only use insulated connectors to join welding cables.
6. Ensure there are no contacts between the workpiece and
work area that would allow it to ground, other than through
the ground cable circuit
7. Do not exceed the duty cycle or amperage required
for the type of welding. Excessive amperage can cause
the deterioration of protective insulation and create a
shock hazard (see Specifications).
8. Unplug the plasma cutting machine when not in use as the
unit as current is still entering the unit, even when it is
turned off.
9. Frequently inspect input power cable for wear and tear,
replace the cable immediately if damaged. Bare wiring is
dangerous and can kill.
10. Do not use damaged, under sized or badly joined cables.
11. Do not disconnect the power cord in place of using the
ON/OFF switch on the tool. This will prevent an accidental
startup when the power cord is plugged into the power
supply.
11.1 In the event of a power failure, turn off the machine as
soon as the power is interrupted. The possibility of

8611303 PROCUT45 PLASMA CUTTER V1.1
18 For technical questions call 1-800-665-8685
accidental injury could occur, if the power returns and
the unit is not switched off.
12. Make certain the power source conforms to requirements
of your equipment (see Specifications).
POWER TOOL PRECAUTIONS
This equipment requires a dedicated 230 volt, 28 amp single-
phase alternating current circuit equipped with a similarly rated
circuit breaker or slow blow fuse. Do not run other appliances,
lights, tools or equipment on the circuit while operating this
plasma cutting machine.
1. Do not drape or carry coiled welding cables on your body
when the cables are plugged into the plasma cutting
machine.
2. Do not start the tool when the electrode is touching the
workpiece.
3. Hold the tool by the insulated gripping surfaces when
performing an operation where it may contact hidden
wiring or its own cord and cables. Contact with a ‘live’ wire
will electrify exposed metal parts and shock the operator.
4. Take work breaks to prevent the tool's motor from
overheating and/or overloading. Refer to the plasma
cutting machine’s duty cycle in Specifications.
5. Keep hands away from the electrode and the area it is
being applied to when the tool is in operation.
6. Do not connect the plasma cutting machine ground clamp
to an electrical conduit. Do not weld on an electrical
conduit.
7. Do not touch the electrode or welded surface immediately
after use. The surface will be hot and may cause an injury.
8. Never use a tool with a cracked or worn electrode. Change
the electrode before using and discard the damaged one.

ELECTROMAGNETIC FIELDS
WARNING! Stop welding immediately and move away from
the plasma cutting machine if you feel faint, dizzy, nausea or
shocks. Seek medical attention.
Electromagnetic Fields (EMF) can interfere with electronic
devices such as pacemakers. Anyone with a pacemaker should
consult with their doctor before working with or near an arc
welding unit. The following steps can minimize the effects of
electromagnetic fields.
1. Twist or tape cables together and prevent coils.
2. Do not drape cables on your body.
3. Keep the welding power source and cables as far away
from the user as practical. A minimum of 24 in. is
recommended.
4. Connect the workpiece clamp as close to the weld as
possible, but lay the electrode and workpiece cables away
from the user.
5. Use the lowest current setting possible during welding.
6. Avoid long and regular bursts of energy while welding.
Apply the electrode in short strokes and intermittently. This
will prevent the pacemaker from interpreting the signal as a
rapid heartbeat.
7. Do not allow the electrode to touch the metal while welding.
8. Wrap the lead cable and ground cable together whenever
possible.
9. Keep the lead cable and ground cables on the same side of
your body.
