Safety Precautions

Read entire section before starting installation

WARNING!

Electric Shock can kill Only qualified personnel should perform this installation. Turn off input power at the

fuse box before working on this equipment. Do not touch electrically live parts. Always connect the machine

to an earthed mains supply as per national recommended standards.

Select suitable location

Place the plasma cutter where clean cooling air can freely circulate in and out of the front & rear louver vents.

Dirt, dust or any foreign material that can be drawn through vents into plasma cutter must be kept to a minimum.

Failure to observe these precautions can result in excessive operating temperatures which can lead to plant

failure.

Grinding

Do not direct grinding particles towards the plasma cutter. An abundance of conductive material can cause

plant failure.

Transport Unloading

Never underestimate the weight of equipment, never move or leave suspended in the air above people.

Use recommended lifting equipment at all times.

WARNING!

Falling Equipment can cause injury. Never lift plasma cutter with gas bottle attached. Never lift above personnel.

Tilting

Machine must be placed on a secure level surface or on a recommended undercarriage/trolley. This machine

may topple over if this procedure is not followed.

Environmental Rating

The plasma power source carries the IP21S rating. It may be used in normal industrial and commercial

environments. Avoid using in areas where water / rain is around.

Electrical Installation

WARNING!

ELECTRIC SHOCK CAN KILL

Machine grounding and High Frequency Interference Protection

This plasma cutter must be grounded to earth. See national electrical codes fro proper grounding methods. The

high frequency generator being similar to a radio transmitter may cause interference to radio, TV and other

electronic equipment. These problems may be the result of radiated interference. Proper grounding methods

can reduce or eliminate this. Radiated interference can develop in the following ways

1. Direct interference from welder power source

2. Direct interference from the welding leads

3. Direct interference radiated from feedback into power lines

4. Interference from re-radiation by un-grounded metallic objects.

Keeping these contributing factors in mind, installing equipment as per following instructions

should minimize problems.

1 Keep the welder input power lines as short as possible and enclose as much of them as possible in

metal conduit or equivalent shielding. There should be a good electrical contact between this conduit and

ground (Earth).

2 Keep the work and electrode leads as short as possible. Tape the leads together where practical.

3 Be sure the torch and earth leads rubber coverings are free from cuts and cracks that allow welding

power leakage

4 Keep earth lead connection to work in good condition Clean area on workbench where earth clamp is

situated on a regular basis.

Input Connections

Make sure the voltage, phase and frequency of input power is as specified on machine rating plate located

at rear of machine.

Have a qualified electrician provide suitable input power as per national electrical codes. Make sure machine

is earthed / grounded.

Make sure fuse or circuit breaker is correct rating for machine. Using fuses or circuit breakers smaller than

recommended will result in nuisance shut off from welder inrush currents even if cutting at low amperages.

Failure to follow these instructions can cause immediate failure within the welder and void machines warranty.

Turn the input power OFF at the mains switch & fuse box before working on this equipment. Have a qualified

electrician install & service this equipment. Allow machine to sit for 5 minutes minimum to allow the power

capacitors to discharge before working inside this equipment. Do not touch electrically live parts

The PLASMA I-CUT 100P Plasma Cutters require a 415V 50/60Hz 3-Phase supply. It requires a 32A fuse. It

comes with a 3 metre mains cable attached. Connect wires according to national coding.

Brown, Black, Grey wires = Live

Green/Yellow Wire Earth (Ground)

Connecting to a mains electrical supply

THIS MACHINE IS OF AN INDUSTRIAL SPECIFICATION AND MUST BEFITTED

TO A 32AMP 415V MAINS INPUT - FAILURE TO RUN ON CORRECT SUPPLY

WILL IN-VALIDATE WARRANTY

Connecting to an Engine Driven Generator

If connecting this Plasma Cutter to an engine driven generator please ensure

the following

Minimum Generator KVA Output 15KVA continuous

Generator to be fitted with AVR (automatic voltage regulation)

DO NOT USE ON A GENERATOR WITHOUT AVR

Connecting to a generator without the above minimum requirements will

invalidate your warranty.

Connections for PLASMA I-CUT 100P

Front machine connections

Fig 2

1. Earth / Work piece connector

Connect the earth lead to this connector. Insert male connector into socket and twist clockwise

until tight. Secure other end of earth lead to work piece via the earth clamp.

2. FUSE

Pilot arc fuse

3. Torch power connector

Connect the main torch euro socket by locating and pushing in and the screw retainer clockwise

until tight.

Note: The head of torch has a safety feature, the machine will not work

if protective shroud is removed.

Controls and Settings

Fig 1

1. Air pressure gauge

This shows the air pressure as set by regulator at rear of machine. This should be set to 70PSI when

the test gas button is activated.

2. Amperage control knob

This adjusts the amperage (cutting power) from 20 to 100 amps

3. L.E.D amperage display

When cutting this shows the actual cutting amperage

4. Test Gas / Cutting selector switch & Post flow air timer

When in the down position this is test gas mode, when setting air pressure switch to test gas so you

obtain actual air flow cutting pressure. When in the up position this is cutting mode, you can now

start cutting, the knob controls post flow air from 3 - 15 seconds and cools the torch head after

cutting. We recommend a minimum of 10 seconds (12 o'clock position) to pro-long torch tip life and if

cutting at 100amps to turn to maximum - 15 seconds.

5. Auto / Standard switch

When in the down position this is in standard cutting mode, this is the normal operating position for

plasma cutting with a hand held and machine type torch, When in the up position this is in auto mode

(4T) this is for special applications when using automated machinery.

6. Indication of too low air pressure

The led will be shown when the air pressure is less than 26psi and the machine will not work. Adjust

pressure to correct 70psi, led will go out and you can resume cutting.

7. Indication of too low air pressure

This regulates the air pressure as displayed in gauge on front of machine. To adjust pressure pull

knob outwards and turn to adjust pressure, once correct pressure is obtained press knob inwards to

secure.

Operating machine

SAFETY PRECAUTIONS

WARNING!

ELECTRIC SHOCK CAN KILL

Do not touch electrically live parts or electrode with skin or wet clothing.

Insulate yourself from work and ground

Always wear dry insulating gloves

WARNING!

FUMES AND GASES can be dangerous

Keep your head out of fumes & gases produced from welding. Use ventilation or exhaust to remove

fumes & gases from breathing zone and general area.

WARNING!

WELDING SPARKS can cause fire or explosion

Keep flammable material away from work area. Do not weld on containers that have held combustibles

WARNING!

ARC RAYS can burn

Wear eye, ear and body protection Make sure work area is protected by proper shielding to avoid injury

to passers by.
