WARNING! Ensure you have read and understood the safety instructions in 2.3. before connecting or operating the air supply.
4.1.
An external compressed air supply must be attached to the PP25 plasma inverter. The supply must produce 5-6 bar with a delivery
of 100 ltr/min. Note that the maximum pressure must not exceed 8 bar.
4.2.
To avoid excessive wear of the inverter ensure that the air supply is clean
and free from moisture. We recommend connection to a clean air system
as shown in fig. 1.
4.3.
The compressor air inlet filter should be cleaned weekly.
4.4.
Line pressure should be increased to compensate for unusually long air
hoses (over 8 metres). The minimum hose bore should be 10mm and
fittings must have the same inside diameter.
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.

2.2. GENERAL SAFETY
DANGER!
Direct contact with the plasma inverter circuit or torch is dangerous. You MUST unplug the inverter from the mains power
supply, (and the compressed air supply - PP25) before connecting or disconnecting cables or performing maintenance or service.
Keep the plasma inverter, cables and torch in good condition.
Take immediate action to repair or replace damaged parts.
Use recommended parts and accessories only.
Unapproved parts may be dangerous and will invalidate the warranty.
Only use the cutting torch provided and ensure that any replacement is of the same type.
Use the plasma inverter in a suitable work area. Ensure that the area has adequate ventilation as cutting fumes are harmful.
For enclosed areas we recommend the use of an air and smoke extraction system. If you are not able to provide adequate extraction
and/or ventilation, wear a respirator suitable for protection against toxic fumes, smoke and gases.
Ensure that there are no obstructions to the flow of clean cool air and ensure that there are no conductive dusts, corrosive vapours or
humidity which could enter the unit and cause serious damage.
WARNING:
Use a welding head shield to protect your eyes and avoid exposing skin to the ultraviolet rays given off by the electric arc.
Always wear protective clothing, insulating gloves and shoes. Keep all protective items clean and undamaged.
Remove ill fitting clothing before wearing protective clothing. Also remove ties, watches, rings and other loose jewellery and contain long hair.
Stand correctly, keeping a good footing and balance and ensure that the floor is not slippery. Wear non-slip shoes.
Ensure that the workpiece is correctly secured before cutting.
Avoid unintentional contact with the workpiece. Accidental or uncontrolled switching on of the torch may be dangerous and will wear the nozzle.
Keep unauthorised persons away from the work area. Any persons working within the area must wear the same protective items as the operator.
DO NOT use cables and torch if the insulation is worn or connections are loose.
DO NOT attempt to fit any unauthorised torch or other component to the plasma cutting unit.
DO NOT cut surfaces that are painted, galvanic coated, oily or greasy.
DO NOT use cables over 10m in length.
DO NOT connect the return cable to any structure which is not part of the workpiece (other than a metal work bench supporting the workpiece).
DANGER!
DO NOT cut near flammable materials - solids, liquids, or gases. Remove all flammable materials such as waste rags etc.
DO NOT cut containers or pipes which have held flammable materials - gases, liquids or solids. DO NOT cut materials that have been
cleaned with chlorinated solvents (or near such solvents) as vapours from the arc action may produce toxic gases.
DO NOT operate the inverter while under the influence of drugs, alcohol or intoxicating medication, or if tired.
DO NOT use the plasma inverter for a task it is not designed to perform.
DO NOT operate the plasma inverter if any parts are damaged or missing as this may cause failure and/or personal injury.
DO NOT carry, or pull, the inverter by the leads or cables. DO NOT strain or bend the cables, protect them from sharp or abrasive items and
DO NOT stand on them.
Protect cables from heat. Long lengths of slack must be gathered and neatly coiled. DO NOT place cables where they will endanger others.
DO NOT hold unsecured workpiece in your hand.
DO NOT get the plasma inverter 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 will 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.
2.3. AIR SUPPLY GENERAL SAFETY - PP25 only
WARNING!
Turn off the air supply and de-pressurise the air line before disconnecting from the inverter. Failure to comply with this instruction
may damage the unit and will invalidate your warranty.
WARNING!
Ensure that correct air pressure is maintained and not exceeded. Recommended pressure 5 bar, required air flow 100ltr/min.
WARNING!
DO NOT
exceed maximum entry pressure of 8 bar. 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 inverter by the hose, or yank the hose from the air supply and DO NOT direct air from the air hose at yourself or others.
If not already fitted, route the carry strap as shown.
