DO NOT operate the plasma cutter while under the influence of drugs, alcohol or intoxicating medication, or if tired.
DO NOT use the plasma cutter for a task it is not designed to perform.
DO NOT operate the plasma cutter if any parts are damaged or missing as this may cause failure and/or personal injury.
DO NOT carry, or pull cutter by leads or cables. DO NOT strain or bend cables. DO NOT stand on cables or leads. Protect from heat and
sharp or abrasive items. long lengths of slack must be gathered and neatly coiled. DO NOT place cables where they endanger others.
DO NOT get the plasma cutter wet or use in damp or wet locations or areas where there is condensation.
DO NOT touch the workpiece close to the cut as it will be very hot. Allow to cool. The cut edge of the workpiece may also be very sharp.
DO NOT touch the torch immediately after use. Allow the torch to cool.
When not in use store the unit in a safe, dry, childproof area.
1.3. AIR SUPPLY GENERAL SAFETY
WARNING! Turn off air supply and de-pressurise the system before connecting or disconnecting cables or performing maintenance or service.
WARNING! ensure that correct air pressure is maintained and not exceeded. Recommended pressure 65-75psi, required air flow 120ltr/min.
WARNING! DO NOT exceed maximum pressure of 90psi. excessive pressure may cause damage and/or personal injury.
Keep air hose away from heat, oil and sharp edges. Check air hose for wear before each use and ensure that all connections are secure.
DO NOT carry the cutter by the hose, or yank the hose from the air supply and DO NOT direct air from the air hose at yourself or others.

No further assembly is required.
4. AIR SUPPLY
WARNING! Ensure that you read and understand the safety instructions in 1.3. before connecting the air supply.
4.1.
An external compressed air supply must be attached to the plasma cutter. The supply must produce a working pressure of 65-75psi with
a capacity of 120ltr/min. The maximum entry pressure into the unit must not exceed 90psi.
4.2.
To avoid excessive wear of the cutter ensure that the air supply is clean
and free from moisture. We recommend the fitting of a water separator/
filter unit as shown in fig. 2.
4.3.
The air inlet filter system should be cleaned weekly.
4.4.
line pressure should be increased to compensate for unusually long air
hoses (over 8 metres). The minimum hose I.d. should be 10mm and
fittings must have the same bore.
4.5.
Keep hose away from heat, oil and sharp edges. Check hoses for wear,
and make certain that all connections are secure.
Note: DO NOT use an oiler in the air system, the air must remain DRY at all times.
5. CONTROL INSTRUCTIONS
WARNING! Before operating the machine ensure that you read, understand and apply Section 1 safety instructions. Ensure that the
machine is disconnected from the power supply before moving or changing accessories.
5.1.
Locating the machine
5.1.1. ensure that the work area has a good airflow and that there is no dust, smoke or gas present.
5.1.2. ensure that there is a minimum clearance of 500mm around the machine and there are no obstacles to prevent a cool air flow.
Also check to ensure that the ventilation grills are not blocked.
5.1.3. When moving the machine, disconnect the unit from the mains power supply and gather all cables safely.
5.2.
Connecting the earth cable
Connect the work cable clamp to the workpiece or to the metallic workbench as follows:
5.2.1. Check that there is a good electrical contact. Caution: ensure that you have made good contact on oxidised or insulated sheets.
5.2.2. Make the earth connection as close to the cutting area as possible.
5.2.3. DO NOT use metal structures or objects to make the earth contact (other than a metal workbench which is holding workpiece). To do so
may endanger the system safety and will give a poor cut. DO NOT make the earth connection to the part of the workpiece that will be removed.
5.3.
ON/OFF switch
5.3.1. The on/off switch is located on the front panel of the machine (fig. 3.1). When the switch is in the "O" position the machine is turned off.
The machine is supplied set to operate on a 415V supply. To operate on a 230V supply, remove the change switch locking screw (fig. 3.2)
and refit in the hole on the left hand side of the change switch. When the switch is in either the 230V or the 415V position, the green light
(fig. 3.3) will illuminate. The control and duty circuits are now live but the torch will remain in 'stand-by' mode until the torch button is pressed.
5.4.
Range selector
5.4.1. The cutting current is regulated by the switch on the front panel (fig. 3.4). This switch regulates the supply of current required in order to
cut different thicknesses of metal at different rates of progress.
