WARNING! Be very cautious if using a generator to power the welder. The generator must be self-regulating and stable with regard
‰
to voltage, wave form and frequency. The output must be greater than the power consumption of the welder. If any of these requirements
is not met the electronics within the welder may be affected.
NOTE: The use of an unregulated generator may be dangerous and will invalidate the warranty on the welder.
WARNING! The welder may produce voltage surges in the mains supply which can damage other sensitive equipment
‰
(e.g. computers). To prevent this happening, it is recommended that the welder is connected to a power supply that does not
feed any sensitive equipment.
IMPORTANT! If using welder to full capacity, we recommend a 16amp supply. We recommend you discuss the installation of a
16amp industrial round pin plug and socket with your electrician.
1.2.
GENERAL SAFETY
▲
DANGER! Unplug the welder from the mains power supply before performing maintenance or service.
Keep the welder and cables in good working order and condition. Take immediate action to repair or replace damaged parts.
9
Use genuine parts and accessories only. Unapproved parts may be dangerous and will invalidate the warranty.
9
Use an air hose to regularly blow out any dirt from the liner and keep the welder clean for best and safest performance.
9
Check and spray the gas cup and contact tip regularly with anti-spatter spray, available from your Sealey stockist.
9
Locate welder in a suitable work area. Ensure that the area has adequate ventilation as welding fumes are harmful.
9
Keep work area clean, tidy and free from unrelated materials. Also ensure the working area has adequate lighting and that a fire
9
extinguisher is at hand.
WARNING! Use welding head shield to protect eyes and avoid exposing skin to ultraviolet rays given off by electric arc. Wear
‰
safety welding gauntlets.
Remove ill fitting clothing, remove ties, watches, rings and other loose jewellery and contain long hair.
9
Ensure the workpiece is correctly secured before welding.
9
Avoid unintentional contact with the workpiece. Accidental or uncontrolled use of the torch may be dangerous and will wear the nozzle.
9
Keep unauthorised persons away from the work area. Any persons working within the area must wear a protective head shield and gloves.
9
Operators must receive adequate training before using the welder.
9
Stand correctly keeping a good footing and balance, ensure the floor is not slippery and wear non-slip shoes.
9
DO NOT operate the welder if it or the cables are damaged and DO NOT attempt to fit any unapproved torches or other
8
components to the welder.
DO NOT get welder wet or use in damp or wet locations or areas where there is condensation.
8
▲
DANGER! DO NOT weld near flammable solids, liquids or gases and DO NOT weld containers or pipes which have held
flammable materials. Avoid welding materials which have been cleaned with chlorinated solvents or welding near such solvents.
DO NOT stand welder on a metal workbench, car bodywork or similar.
8
DO NOT touch any live metal parts of the torch or electrode while the machine is switched on.
8
DO NOT pull the welder by the cable, or the torch. Protect cables from sharp or abrasive items. DO NOT bend, strain or stand on cables
8
or leads.
Protect from heat. Long lengths of slack must be gathered and neatly coiled. DO NOT place cables where they endanger others.
9
DO NOT touch the torch or workpiece immediately after welding as they will be very hot. Allow to cool.
8
DO NOT operate welder while under the influence of drugs, alcohol or intoxicating medication, or if tired.
8
When not in use store the welder in a safe, dry, childproof area.

2. INTRODUCTION
IMPORTANT: These instructions contain the information you require to prepare your machine for welding, together with a maintenance
and a troubleshooting section. The instructions are not intended to teach you how to weld. If you have no experience, we recommend that
you seek training from an expert source. MIG welding is relatively easy, but does require a steady hand and supervised practice on scrap
metal, as it is only with continued practice that you will achieve the desired results.
Heavy duty high output transformer and forced air cooling to maximise duty cycle performance. Supplied with comfort grip non-live torch.
1.8m earth cable, 0.45kg flux cored wire and 1mm contact tip. Suitable for no-gas operation only. For use with flux cored wire.
