1. SAFETY
1.1.
ELECTRICAL SAFETY
WARNING!
It is the responsibility of the owner and the operator to read, understand and comply with the following: You must check
all electrical products, before use, to ensure that they are safe. You must inspect power cables, plugs, sockets and any other connectors
for wear or damage. You must ensure that the risk of electric shock is minimised by the installation of appropriate safety devices. A
Residual Current Circuit Breaker (RCCB) should be incorporated in the main distribution board. We also recommend that a Residual
Current Device (RCD) is used. It is particularly important to use an RCD with portable products that are plugged into a supply which is
not protected by an RCCB. If in any doubt consult a qualified 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 that all portable electrical appliances, if used on business premises, are tested by a qualified
electrician, using a Portable Appliance Tester (PAT), at least once a year.
1.1.2.
The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of those
appliances and the safety of the appliance operators. If in any doubt about electrical safety, contact a qualified electrician.
9
Ensure that the insulation of all cables on the appliance is safe before connecting it to the power supply. See 1.1.1. and 1.1.2. and use a
Portable Appliance Tester.
9
Ensure that cables are always protected against short circuit and overload.
9
Regularly inspect power supply cables and plugs for wear or damage and check all connections
to ensure that none is loose.
9
Ensure that the voltage marked on the appliance matches the power supply to be used.
8
DO NOT
pull or carry the appliance by the power cable.
8
DO NOT
pull the plug from the socket by the cable.
8
DO NOT
use worn or damaged cables, plugs or connectors. Have any faulty item repaired or replaced immediately by a qualified
electrician.
1.1.3.
We recommend connection to a supply with a type C breaker. If in doubt you must contact a qualified electrician to ensure that a
suitably rated supply is available.
WARNING!
Be very cautious if using a petrol or diesel generator. The generator must be stable with regard to frequency (H3), voltage
and wave form. The output must be higher than the power (kVA) of the inverter. The generator must also be self regulating. If any A.M.
feature is not respected the working of the regulation card may be affected.
Use of a generator without a regulator may be dangerous and will invalidate your inverter warranty.
1.2.
GENERAL SAFETY
1.2.1.
Operator Safety
9
Operators must receive adequate training before using the inverter.
9
Remove ill fitting clothing, remove ties, watches, rings and other loose jewellery and contain long hair.
8
DO NOT
operate the inverter while under the influence of drugs, alcohol or intoxicating medication, or if tired.
9
Stand correctly keeping a good footing and balance, ensure that the floor is not slippery and wear non-slip shoes.
9
Keep unauthorised persons away from the work area. Any persons working within the area must wear the same protective items.
9
Avoid oily greasy clothing. A spark may ignite them.
8
DO NOT
touch the work piece close to the weld as it will be very hot. Allow to cool.
8
DO NOT
touch the electrode holder immediately after use. Allow the electrode holder to cool.
9
Wear safety welding gauntlets.
1.2.2.
Cable Connections
9
Keep the inverter and cables in good working order and condition. Take immediate action to repair or replace damaged parts.
9
Ensure that there is no obstruction to the flow of clean, cool air and ensure that there are no conductive dusts, corrosive vapours or
humidity which could enter the inverter and cause serious damage.
8
DO NOT
weld containers or pipes which have held flammable materials - gases, liquids or solids.
▲
DANGER!
Avoid welding on materials cleaned with chlorinated solvents or near such solvents. Vapours from chlorinated solvents
(such as de-greasers) can be decomposed by the heat of the arc to form PHOSGENE, a highly toxic gas, and other lung and eye
irritating products. The ultraviolet (radiant) energy of the arc can also decompose trichloroethylene and perchloroethylene vapours to
form phosgene.
