1. SAFETY INSTRUCTIONS
1.1
ELECTRICAL SAFETY.
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 minimised 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 professional electrician. You may obtain a Residual Current
Device by contacting your Sealey dealer. 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 a business premises, to be tested by a qualified person at least
once a year 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 qualified electrician.
1.1.3.
Ensure the insulation on all cables and product itself is safe before connecting to mains power supply. See 1.1.2. use a (PAT) and 1.1.1.
1.1.4.
Ensure that cables are always protected against short circuit and overload.
1.1.5.
Regularly check power supply, leads, plugs and all electrical connections for wear or damage, especially power connections to ensure none are 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 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 damage leads, plugs or connections. Immediately replace or repair by qualified persons. A U.K. 3 pin plug with ASTA/BS approval
is fitted. In case of damage, cut off and fit a new plug according to the following instructions (UK only - see diagram).
a) p WARNING! Ensure the unit is correctly earthed via a three-pin plug.
b) Connect the Green/Yellow 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’.
NOTE: Model MW100 should already be connected to a power plug.
1.1.10.p
WARNING! Be very cautious if using a diesel generator. The generator
must be stable with regard to frequency (H3), voltage and wave form. The power must
p
be higher than the power in KVA of the inverter machine. The diesel generator must also be self regulating.
If any A.M. feature is not respected the working of the regulation card may be affected.
NOTE: Use of a generator without a regulator may be dangerous and will invalidate your inverter warranty.
1.2
GENERAL SAFETY
s
DANGER!: unplug the inverter from the mains power supply before connecting or disconnect cables or performing maintenance or service. Direct
contact with the inverter circuit is dangerous.
s
3 Keep the inverter and cables in good working order and condition. (Take immediate action to repair or replace damaged parts).
3 Use genuine parts and accessories only. (Non recommended parts may be dangerous and will invalidate the warranty).
3 Keep the inverter clean for best and safest performance.
3 Locate inverter in adequate working area for its function. Ensure area has adequate ventilated as welding fumes are harmful.
p
WARNING! Connecting cables must be turned fully into the quick plugs to ensure a good electrical contact, loose connection will cause
overheating, rapid deterioration and loss in efficiency.
p
3 Ensure there is no obstruction to the flow of clean cool air and ensure there are no conductive dusts, corrosive vapours or humidity which could enter the
inverter and cause serious damage.
3 Keep working area clean and tidy and free from unrelated materials. Also ensure the working area has adequate lighting.
p
WARNING: use welding head shield to protect eyes and avoid exposing skin to ultraviolet rays given off by electric arc. Wear safety welding gauntlets.
3 Remove ill fitting clothing, remove ties, watches, rings, and other loose jewellery, and contain long hair.
p
3 Ensure the workpiece is correctly secured before operating the inverter.
3 Avoid unintentional contact with workpiece. Accidental or uncontrolled switching on of the torch may be dangerous and will wear the nozzle.
3 Keep unauthorised persons away from the working area, and any persons working within the area must adorn the same protective items.
3 Operators must receive adequate training before using the inverter. The inverter must only be operated under supervision.
3 Stand correctly keeping a good footing and balance, ensure the floor is not slippery, and wear non-slip shoes.
p
WARNING: When unit is switched off the short-circuit light (fig 4. B) will come on for 10-15 seconds whilst capacitor discharges. DO NOT open unit until light goes out.
3 Turn voltage switch to "0" (off) when not in use.
p
7 DO NOT operate the inverter if it or its cables are damaged.
7 DO NOT use welding cables over 10m in length.
7 DO NOT attempt to fit any non genuine torches, components, or parts to the inverter unit.
7 DO NOT use any metallic structure which is not part of the work piece to substitute the return cable of the welding current. This may jeopardise results and may
be dangerous. Exception: Metallic work bench but connect as near to weld as possible.
7 DO NOT hit the electrode on the workpiece, this may damage the electrode and make strike-up difficult.
7 DO NOT get inverter wet or use in damp or wet locations or areas where there is condensation.
7 DO NOT weld without a welding safety head shield.
s
DANGER! DO NOT weld near inflammable materials, solids, liquids, or gases.
7 DO NOT weld containers or pipes which have held flammable materials or gases, liquids or solids. Avoid operating on materials cleaned with chlorinated
s
solvents or near such solvents.
7 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 NOT stand on cables or
leads. Protect from heat. Long lengths of slack must be gathered & neatly coiled. DO NOT place cables where they endanger others.
7 DO NOT touch the workpiece close to the weld as it will be very hot. Allow to cool.
7 DO NOT touch the torch immediately after use. Allow the torch to cool.
7 DO NOT operate inverter while under the influence of drugs, alcohol or intoxicating medication, or if fatigued.
3 When not in use store the inverter in a safe, dry, childproof area.
