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 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 shall should 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.

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.

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

enables 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 may light

the matches or ignite leaking lighter fuel.

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.

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 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.

V1.1 80A PROCUT 80 Plasma Cutter 8784480

Visit www.princessauto.com for more information 7

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 en te r.

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.

V1.1 80A PROCUT 80 Plasma Cutter 8784480

Visit www.princessauto.com for more information 9

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.

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.

8784480 80A PROCUT 80 Plasma Cutter V1.1

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

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.

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.

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.

V1.1 80A PROCUT 80 Plasma Cutter 8784480

Visit www.princessauto.com for more information 11

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 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.

8784480 80A PROCUT 80 Plasma Cutter V1.1

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

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.

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.

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.

8784480 80A PROCUT 80 Plasma Cutter V1.1

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

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).

V1.1 80A PROCUT 80 Plasma Cutter 8784480

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 using single-

phase power. Equip with a 30A circuit breaker if using three-phase 30A

alternating current. 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.

8784480 80A PROCUT 80 Plasma Cutter V1.1

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

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 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.

INSTALL THE 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 (Q) on the back of the

plasma cutter. 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

Please install the machine strictly according to the following steps.

1. Connect the plasma torch to the plasma cutting machine. Insert the

plasma torch cable connector into the torch connection (D) and screw

hand tight. Do not bend the pins inside the torch connector (Fig. 2).

2. Connect the earth lead to the output

terminal (E) of the machine and tighten

(Fig. 2).

3. Connect the compressed air/gas supply

to the air connection (Q) located at the

rear of the machine. Turn on the air/gas

supply.

4. Connect the machine to the correct

power supply and switch on the machine using the ON/OFF switch (R)

located at the rear of the machine.

5. Select 2T / 4T operation.

5.1 2T – The arc starts when the trigger is squeezed. The arc stops

when the trigger is released. The trigger must remain depressed

to maintain the electric arc.

5.2 4T – The arc starts when the trigger is squeezed and released.

Squeeze and release the trigger a second time to stop the

electric arc. The electric arc is maintained without having to hold

the trigger.

6. Select Gas Check/Cutting Mode.

6.1 Gas Check – Determine if the gas or air is flowing. Press the button

to switch to Gas Check and the indicator will light up. Pull the

trigger and gas should flow out of the nozzle. The machine does not

supply an electric arc when in this mode.

6.2 Cutting Mode - Press the button again and the cutting mode LED

will light up. The machine is now able to cut.

7. Set amperage control dial (C) to desired amperage.

OPERATION

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 10

minute period. The cutting unit must cool for the remainder of the cycle. This

cutting unit has a duty cycle rating of 40% at the rated output (see

Specifications). This means that the user can cut for 4 minutes and then rest

the welding unit for 6 minutes before using it again.

THERMAL PROTECTION

Constantly exceeding the duty cycle can damage the cutting unit. An internal

thermal protector will open when the duty cycle is exceeded, shutting OFF all

cutting unit functions except the cooling fan. Leave the cutting unit turned ON

with the fan running. The thermal protector will automatically reset and the

cutting unit will function normally again once it has cooled.

Wait at least another 10 minutes after the thermal protector opens before

resuming cutting. Starting before this additional time may result in a

shortened duty cycle

PREPARATION

1. Check that all personal protective gear is in place and properly fitted.

(See Safety – Personal Safety).

2. Check that work area preparations are in place (See Safety – Work

Area).

3. Check that all cables and hoses are connected in the correct manner.
