condition, i.e. without holes.
– In hazardous conditions of increased electric shock
always ensure a second person is present in case of
an accident.
– Never change electrodes with bare hands or damp
gloves (for ARC/MMA welders).
– Keep welding cables away from power cables.
– Regularly inspect the condition of the welding, earth,
and power cables for signs of damage.
– Do not leave the machine unattended and remove
the plug from the socket when not in use.
– Do not use welding cables unsuitable for the
amperage.
– Ensure the earth clamp is adjacent to the weld seam,
secured to bare metal and when not in use is
insulated for safety.
– Keep all equipment well maintained.
– The operator shall prevent gas cylinders in the
vicinity of the workpiece from becoming part of the
welding circuit.
Fumes & Gases can be harmful:
– The welding process generates hazardous fumes as
a by-product. Inhalation of these fumes is hazardous
to health.
– Keep your head away from the weld to avoid
breathing the fumes.
– If welding in confined spaces ensure adequate
ventilation and use a fume extractor.
– Welding fumes displace oxygen. The danger of
suffocation.
– By-products of welding can react with other chemical
vapours to produce a toxic/explosive environment.
Welding can cause fire or explosion:
– Arc welding and allied processes can cause fire and
explosions and precautions shall be taken to
prevent these hazards.
– Before starting a weld ensure the area is clear of
flammable materials.
– Remove any inflammables to a safe distance,
especially substances likely to generate a dangerous
vapour.
– The welding arc can cause serious burns. Avoid
contact with skin.

– 4 –
– Sparks and molten metal are cast out during
welding. Take precautions to prevent fire igniting and
wear protective clothing.
– Sparks and molten metal can pass through gaps. Be
aware that fire can start out of sight. Flammables in a
locked cabinet may not be safe.
– Do not weld pressurised containers.
– Do not weld tanks, drums, or other vessels until they
have been correctly cleaned/prepared for welding.

electrician.
This product’s wiring has insulation stripped in
preparation for wiring a 32A plug (not supplied).
It is designed for connection to a 32 amp power supply
rated at 230V AC.
Because it is constructed mostly of metal parts, it is a
Class 1 machine; meaning, it must have an earth
connection in the power supply. This is to prevent
electrocution in the event of a failure.
Note: Remove the plug from the socket before carrying
out adjustment, servicing or maintenance.
Check that the electrical supply delivers the voltage and
frequency corresponding to the product and that it is
fitted with a delayed fuse suited to the maximum
delivered rated current.

6.5 TORCH ASSEMBLY – FIG.6
Warning! Under no circumstances must the plasma
nozzle be removed or any other work be carried out on
the torch with the machine switched on. Ignoring this
precaution could lead to serious burns or contact with
high DC voltages.
If the machine has just been used for cutting, allow the
cooling air to stop before switching the machine off for
torch servicing.
The torch should be kept free of slag at all times to
ensure the free passage of air.
To assemble / dismantle the torch:
− Invert the torch so the tip points upwards.
− Unscrew and remove the shield cup.
− Remove the tip, swirl baffle and electrode.
− Ensure the torch head thread is upper most.
− Fit electrode into end of torch head.
− Fit swirl baffle onto electrode, ensure is it seated fully
onto the electrode.
− Fit tip onto the swirl baffle.
− Fit shield cup and screw on.
− The tip and electrode need replacing when worn.
− Indication of wear are a loss off cutting capacity or
that the cut is no longer 90°.
− When inspecting the tip look for erosion of the hole in
the centre of the tip or a build up of metal residue.
− When inspecting the electrode look for erosion in
centre of the electrode.

FIG.
7. OPERATION
7.1 BASIC OPERATIONAL
PROCEDURES
− Check all safety instructions have been observed.
− Check correct air supply is connected.
− Drain any water from bowl on the filter regulator (if
fitted).
− Set machine to required current range according to
the thickness of metal to be cut.
Warning! DO NOT change the current range while
cutting.
Caution! DO NOT attempt to cut material beyond the
range specified, as this will damage the torch.
− Check the torch consumables are in good condition.
− Check torch and earth lead connections are tight.
− Connect return lead to the work piece, using an area
free of rust and paint, for a good contact.
− Connect to mains supply and switch on. The power
LED will illuminate.
− Adjust air pressure to the required setting.
− Set the cutting current via the current control, an
indication of the setting will be shown on the LED
amperage display.
− Adjust the post gas control, if cutting at a high current
setting or making a long cut set the control near
maximum, this will give a longer cool time for the
torch.
− Place the torch at the edge of the work piece with the
centre of the tip slightly beyond the edge. Press the
torch trigger. The air will flow after a short delay the
arc will ignite. The torch should be moved steadily
along the work piece at a rate slow enough for the
metal to be cut right through in one pass. If the cut
penetration is incomplete, then the torch could be
damaged. (While the air is flowing, check it is still at
the correct pressure setting.)
− When the cut is complete, release the torch trigger
button. The arc will immediately extinguish, but air
will continue to flow for a short time. DO NOT turn
the machine off until this cooling air has stopped
flowing as this is necessary to prevent damage to the
torch.
Piercing:
When piercing, the torch head should be angled back so
as to allow the molten material to escape to one side.
The normal angle of cut can be resumed once the metal
has been pierced.
Caution! Piercing will reduce the life of the torch.

8. MAINTENANCE AND TROUBLESHOOTING
8.1 TROUBLESHOOTING GUIDE
Problem Possible Cause Required Action
– Plasma arc will not start. – Unit not powered up. – Check mains supply, on/off
switch is on.
– Work clamp connection. – Check ground clamp has a
good connection to the material
being cut, clean surface of
material if it is dirty or corroded.
– Air supply is low pressure. – Check air is flowing from the
torch tip with cut switch
pressed. Check the compressor
is maintaining 60psi at the
gauge while cutting is in
progress. Check the regulator
fittings have been assembled
properly using PTFE tape.
– Check the cutting tip is not
blocked by molten metal
splatter.
– Thermal cut-out light on front
panel of unit comes on.
– Switch machine off and wait
about 2-3 minutes, Switch
machine back on. This can
occur if the unit is overheating
due to a high ambient
temperature.
– Use 32A cable for power lead
extensions, a standard 13A type
is unsuitable if a long extension
is required. If the voltage at the
unit ‘dips’ below the minimum
value as the arc strikes the unit
will turn off and the OC light will
come on.
– Try operating the cutter at 20A
set current, if this is OK then
there is a problem with the
stability of the mains supply to
the unit. Use a different power
source or thicker mains cable to
connect to the unit mains lead.
– Torch Assembly / Air flow. – Check the torch has been
assembled correctly. Note the
presence and position of the
swirl ring.
– Wait for air flow to finish flowing
before operating cutting switch.
Plasma will not start if air is
already flowing from nozzle
when the cutting switch is
pressed.

8. MAINTENANCE AND TROUBLESHOOTING
Problem Possible Cause Required Action
– Plasma arc stops while cutting – Hand too tense, inadvertently
releasing the cut switch.
– Hold the torch lightly against the
material being cut, don’t push
down. Try and relax the hand.
– Cutting speed too slow. – If all material cut from under the
arc the arc will extinguish.
– Torch moved too far away from
material.
– Move torch closer to the metal
to be cut.
– Compressor unable to keep up
with air demand.
– Check air pressure gauge
reading when cut stops.
– Check air pressure gauge is
reading 60psi with cut switch
pressed.
– Check torch lead connections at
unit and torch are tight.
– Check torch hose is
undamaged.
– Check compressor, give the
compressor time to recover if
making long cuts when using a
smaller compressor. Check the
regulator fittings have been
assembled properly using PTFE
tape.
– Sparks are shooting upward not
downward through the material.
– Plasma arc not piercing
material.
– Torch travel speed too fast.
– Check grounding clamp is
making a good connection to
the material being cut and is
tightly connected at the unit.
Clean a patch of material for
clamp if rusty
– Increase current.
