combustible materials within 39 ft (12 metres) of the welding unit.

See Fire and Explosion Precautions.

5. Have a fire extinguisher readily available (see Fire and Explosion

Precautions).

6. Use protective screens or barriers to protect others from flash and

glare; warn others in the area to look away from the arc.

7. Keep the welding unit at least one foot from any wall or structure.

8. Check that the work area is free from fires, sparks or hot debris

before leaving.

9. Store tools properly in a safe and dry location. Keep tools out of

the reach of children.

PERSONAL SAFETY

WARNING! Wear personal protective equipment approved by the

Canadian Standards Association (CSA) or American National

Standards Institute (ANSI).

HEAD PROTECTION

DANGER! Never look directly at the welding arc without the

proper protection. The light can cause flash burn damage and

impair vision. Although treatment is possible, multiple

occurrences can result in permanent eye damage.

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

V1.0 PROCUT 40A Plasma Cutter with Built-In Compressor 9081357

Visit www.princessauto.com for more information 5

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.

2. Do not wear clothes or protective gear that are frayed, oily or

greasy as they may ignite from the heat or ejected slag and sparks.

3. Wear thick clothes that do not expose the skin. Ultraviolet or

infrared light can burn skin with sufficient exposure.

4. Do not wear clothing that can hold hot debris or sparks such as pant

cuffs, shirt pockets or boots. Choose clothing that has flaps over

pockets or wear clothing to cover the openings such as pant legs over

the boots or an apron over the shirt.

5. Gloves must contain an insulating lining to protect against an

electric shock.

6. Rubber soled footwear or electrically insulated work boots are

recommended while working with a welding unit. The non- skid sole

is will also help maintain footing and balance during work.

9081357 PROCUT 40A Plasma Cutter with Built-In Compressor V1.0

6 For technical questions call 1-800-665-8685

6.1 Select boots with steel toe protection to prevent injury from

falling objects.

RESPIRATORS

1. Respiratory protection is needed when ventilation is not 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 suffering from oxygen

deprivation.

PERSONAL PRECAUTIONS

Control the tool, personal movement and the work environment to avoid

personal injury or damage to the tool.

1. Do not operate any tool when tired or under the influence of drugs,

alcohol or medications.

2. Avoid wearing clothes or jewelry that can become entangled with

the moving parts of a tool. Keep long hair covered or bound.

3. Remove all jewelry or metal items from your person before welding.

Metal items may connect to the welding unit’s electrical circuit,

causing an injury or death.

4. Do not overreach when operating the tool. Proper footing and balance

enable better control in unexpected situations.

5. Support the workpiece or clamp it to a stable platform. Holding the

workpiece by hand or against your body may lead to personal

injury.

6. Do not wear any personal grooming products that are flammable,

such as hair preparations, perfume or cologne with an alcohol base.

7. Remove any combustibles, such as butane lighters or matches,

from your person before doing any welding. Hot welding sparks

SPECIFIC SAFETY PRECAUTIONS

WARNING! DO NOT let comfort or familiarity with product (gained

from repeated use) replace strict adherence to the tool safety

rules. If you use this tool unsafely or incorrectly, you can suffer

serious personal injury.

CAUTION! Only use compressed air with this plasma cutter. Other

gases can damage the machine.

Welding produces sparks, molten slag, intense white light, plus infrared

and ultraviolet light. Any of these can cause direct harm to the eyes and

skin of the welder or bystanders.

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

surface 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.

9081357 PROCUT 40A Plasma Cutter with Built-In Compressor V1.0

8 For technical questions call 1-800-665-8685

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.

18. Keep the plasma cutter out of direct sunlight.

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.

V1.0 PROCUT 40A Plasma Cutter with Built-In Compressor 9081357

Visit www.princessauto.com for more information 9

1.2 Check both sides of a panel or wall for combustible material.

Remove the combustible material before welding.

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.

9.1 Welding a combustible metal like zinc, magnesium or titanium

requires a Type D fire extinguisher.

9081357 PROCUT 40A Plasma Cutter with Built-In Compressor V1.0

10 For technical questions call 1-800-665-8685

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.

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.

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.

V1.0 PROCUT 40A Plasma Cutter with Built-In Compressor 9081357

Visit www.princessauto.com for more information 11

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.

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.

9081357 PROCUT 40A Plasma Cutter with Built-In Compressor V1.0

12 For technical questions call 1-800-665-8685

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.

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.

V1.0 PROCUT 40A Plasma Cutter with Built-In Compressor 9081357

Visit www.princessauto.com for more information 13

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.

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 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, 50-amp single-phase

alternating current circuit equipped with a similarly rated circuit breaker when

9081357 PROCUT 40A Plasma Cutter with Built-In Compressor V1.0

14 For technical questions call 1-800-665-8685

using single-phase power. 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.

V1.0 PROCUT 40A Plasma Cutter with Built-In Compressor 9081357

Visit www.princessauto.com for more information 15

5. Use the appropriate current setting during cutting.

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.

UNPACKING

WARNING! Do not operate the tool if any part is missing. Replace

ASSEMBLY & INSTALLATION

Letter references in parenthesis (A) refer to the included Identification Key.

INTERNAL/EXTERNAL AIR SOURCE

The plasma cutter has a built-in air compressor to operate without the

need of an external air source. You still have the option to use an

external compressor if desired or convenient.

Install the included air regulator. It will filter the air when using the

internal compressor. The air regulator also has an air inlet (N) to

connect to an air hose.

INSTALL THE EXTERNAL AIR SOURCE

The plasma cutter uses compressed air with the plasma arc to create

an ionized cutting arc. A compressor is the best choice to provide air,

but a cylinder of compressed air may be an option when a compressor

is not available.

1. Follow operating and set up instructions in the compressor’s manual

before connecting to the plasma cutter.

2. Connect the air hose to the air inlet (N) on the air regulator. Use

thread sealant to prevent air leaks.

3. Install an air dryer on the compressor air hose to prevent moisture

from reaching the plasma cutter. Remember to compensate for the

slight loss of air pressure the air dryer will cause.

SET UP PROCEDURE FOR PLASMA CUTTING

diagram included with the CNC cable plug and follow the wiring

instructions from the CNC equipment manufacturer.

Connect the included CNC plug into the CNC port (J). Follow the

instructions of the CNC equipment manufacturer to connect and operate

the welding and CNC machine.

OPERATION

CAUTION! Do not use an extension lead with the plasma cutter. The

additional lead length may cause an increase in amperage draw

and overheating. Only use the supplied lead for your cutting tasks.

CAUTION! Only use compressed air with this plasma cutter. Other

gases can damage the machine.

AIR PLASMA CUTTING TECHNOLOGY

A plasma cutter operates by passing an electric

arc from an electrode (Fig. 3-5) through a gas

such as nitrogen, air, argon or oxygen that is

forced through the air diffuser (Fig. 3-4) then a

constricted nozzle (Fig. 3-2). The shield cup

contains and directs the initial air/gas (Fig. 3-6).

The gas temperature is raised until it becomes

superheated plasma (Fig. 3-3). The plasma cuts

through the metal while carrying the electrical charge. The charge transfers

to the metal and ground cable, completing the electrical circuit.

The electrode has an insert of tough high conductive material such as

hafnium and cerium (Fig. 3-1). The nozzle and electrode require periodic

replacement due to erosion with use. Clean, dry air improves the lifespan of

the electrodes and nozzle. A plasma air filter is recommended.

OVER-VOLTAGE

This equipment has an automatic voltage compensation function, which

enables the unit to maintain the voltage within the given range. In case

that the input voltage or amperage exceeds the stipulated value, it is

possible to damage the equipment’s components. Please ensure your

primary power supply is correct (See Specifications).

DUTY CYCLE

The cutting unit’s duty cycle rating defines how long the operator can cut

before allowing the cutting unit to cool. The duty cycle is a percentage of a
