SAFETY

1.1.ELECTRICAL SAFETY.
WARNING! It is the user’s responsibility to check the following: You must check all electrical equipment and appliances to ensure they are safe before using. You must  inspect power supply leads, plugs and all electrical connections for wear and damage. You must ensure the risk of electric shock is minimized by the installation of appropriate  safety devices. An RCCB (Residual Current Circuit Breaker) should be incorporated in the main distribution board. We recommend that an RCD (Residual Current Device) is
used with all electrical products. It is particularly important to use an RCD together with portable products that are plugged into an electrical supply not protected by an RCCB.  If in doubt consult a competent electrician. You may obtain a Residual Current Device by contacting your Sealey stockist. You must also read and understand the following instructions concerning electrical safety.
1.1.1. The Electricity At Work Act 1989 requires all portable electrical appliances, if used on business premises, to be tested by a competent person on a regular basis by using a Portable Appliance Tester (PAT).
1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of the appliance, and the safety of the appliance operator. If in any doubt about electrical safety, contact a competent electrician.
1.1.3. Ensure the insulation on all cables and the product itself is safe before connecting to the main power supply. See 1.1.1. use a Portable Appliance Tester (PAT).
1.1.4. Ensure that cables are always protected against short circuits and overloads.
1.1.5. Check power supply, leads, plugs, and all electrical connections regularly for wear or damage, especially power connections to ensure none is loose.
1.1.6. Check the voltage marked on the product is the same as the electrical power supply to be used. Check fused plugs are fitted with the correct capacity fuse.
1.1.7. DO NOT pull or carry the powered appliance by its power supply lead. Products such as inverters must not be pulled or carried by their output cables.
1.1.8. DO NOT pull power plugs from sockets by the power cable.
1.1.9. DO NOT use worn or damaged leads, plugs, or connections. Replace or have repaired immediately by competent persons. In case of damage, cut off and fit a new plug according to the following instructions.
1.1.10. NO plug is fitted to this machine. Whilst it is possible to perform TIG welding at lower power settings using a 13Amp mains source, ordinary ARC welding (without gas) and TIG welding at higher power settings will require the machine to be connected
to a 30A supply either by direct wiring into your mains circuit or by fitting an industrial round pin plug & socket for more flexible usage.
In either case, we recommend you contact a competent electrician to assess your existing wiring installation and follow the recommendations in full. Particular attention should be paid to the provision of adequate fuses on the mains circuit and to the earthing of the machine.If a 13A power source is used wire the plug as shown to the right.
a) **WARNING! Ensure the unit is correctly earthed via a three-pin plug.
b) Connect the Yellow/Green earth wire to the earth terminal ‘E’.
c) Connect the Brown live wire to live terminal ‘L’.
d) Connect the Blue neutral wire to the neutral terminal ‘N’.
RECOMMENDED FUSE RATING13AMP: TO GAIN MAXIMUM OUTPUT THE INVERTER MUST BE CONNECTED TO A 30AMP SUPPLY
WARNING! Be very cautious if using a generator to power the Inverter. The generator must be self regulating and stable with regard to voltage, waveform, and frequency. The output must be greater than the power consumption of the inverter. If any of these requirements are not met the electronics within the Inverter may be affected.
NOTE: The use of an unregulated generator may be dangerous and will invalidate the warranty on the inverter.
WARNING! The inverter may produce voltage surges in the main supply which can damage other sensitive equipment (e.g. computers). To avoid this happening it is recommended that the Inverter is connected to a power supply that does not feed any sensitive equipment.
1.2. GENERAL SAFETY
▲ DANGER! Unplug the inverter from the mains power supply before connecting or disconnecting cables or performing maintenance or service. Direct contact with the inverter circuit is dangerous.
Keep the inverter and cables in good working order and condition. (Take immediate action to repair or replace damaged parts).
Use genuine parts and accessories only. (Non-recommended parts may be dangerous and will invalidate the warranty).
Locate the inverter in an adequate working area for its function. Ensure the area has adequate ventilation as welding fumes are harmful.
WARNING! If it is necessary for you to assemble the work clamp cable, ensure that sufficient copper strands are exposed and
turned back to make full contact within the dense plug to ensure good electrical contact. A loose connection will cause overheating, rapid deterioration, and loss of efficiency.
Ensure there is no obstruction to the flow of clean cool air through the ventilation apertures and ensure there are no conductive dust, corrosive vapors, or humidity that could enter the inverter and cause serious damage.
Keep the working area clean and tidy and free from unrelated materials. Also, ensure the working area has adequate lighting.
WARNING! Use a 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 jewelry, and contain long hair.
Ensure the workpiece is correctly secured before operating the inverter.
Avoid unintentional contact with the workpiece. Accidental or uncontrolled switching on of the torch may be dangerous and will cause the nozzle to wear.
Keep unauthorized persons away from the working area, and any persons working within the area must wear the same protective items as the user.
Operators must receive adequate training before using the inverter. The inverter must only be operated under supervision.
Stand correctly keeping a good footing and balance, ensure the floor is not slippery, and wear non-slip shoes.
WARNING! When the unit is switched off wait for 15 seconds whilst the capacitors discharge before opening the case.
Turn the voltage switch to “0” (off) when not in use.
DO NOT operate the inverter if it or its cables are damaged.
DO NOT use welding cables over 10m in length. (Cables should be as short as possible).
  DO NOT attempt to fit any nongenuine torches, components, or parts to the inverter unit. To do so may cause damage and will invalidate the warranty.
DO NOT use any metallic structure which is not part of the workpiece as a substitute for the return cable. This may jeopardize results and may be dangerous. Exception: Metallic workbench, but connect as near to weld as possible.
DO NOT hit the electrode on the workpiece, this may damage the electrode and make strike-up difficult.
DO NOT get the inverter wet or use it in damp or wet locations or areas where there is condensation.
▲ DANGER! DO NOT weld near inflammable materials, solids, liquids, or gases.
DO NOT weld containers or pipes which have held flammable materials or gases, liquids, or solids. Avoid operating on materials cleaned with chlorinated solvents or near such solvents.
DO NOT pull the inverter by the cable, or the torch, and DO NOT bend or strain cables, protect from sharp or abrasive items, and DO
Do NOT stand on cables or leads. Protect from heat. Long lengths of slack must be gathered & neatly coiled. DO NOT place cables where they may endanger
DO NOT touch the workpiece close to the weld as it will be very hot. Allow cooling.
DO NOT touch the torch immediately after use. Allow the torch to cool.
DO NOT** operate the inverter while under the influence of drugs, alcohol, or intoxicating medication, or if fatigued.
When not in use store the inverter in a safe, dry, childproof area.
