1. SAFETY INSTRUCTIONS
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 dealer. 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.
1.1.3. ensure that the insulation on all cables and 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.
1.1.4. ensure that cables are always protected against short circuit and
overload.
1.1.5. Regularly inspect power supply cables and plugs for wear or damage
and check all connections to ensure that none is loose.
1.1.6. Important: ensure that the voltage marked on the appliance matches
the power supply to be used and that the supply is correctly fused.
1.1.7. DO NOT pull or carry the appliance by the power cable.
1.1.8. DO NOT pull the plug from the socket by the cable.
1.1.9. DO NOT use worn or damaged cables, plugs or connectors.
Immediately have any faulty item repaired or replaced by a qualified
electrician.
1.1.10. MIGHTYMIG170, MIGHTYMIG190, MIGHTYMIG210 are single phase
machines and must be run from a minimum 16amp supply.
To achieve maximum output these models will require a 30Amp
fused supply. We recommend you discuss the installation of an
industrial round pin plug and socket with your electrician.
Fit a plug according to the following instructions (UK only).
a) Connect the GREEN/YELLOW earth wire to the earth terminal ‘E’.
b) Connect the BROWN live wire to the live terminal ‘L’.
c) Connect the BLUE neutral wire to the neutral terminal ‘N’.
d) After wiring, check that there are no bare wires, that all wires
have been correctly connected, that the cable outer insulation
extends beyond the cable restraint and that the restraint is tight.
1.1.11. When a cable extension reel is used it should be fully unwound before
connection. A cable reel with an RCd fitted is recommended since any
product which is plugged into the cable reel will be protected. The
cross-section of the cable on the cable reel must be suitable for the unit
and never lower than the cross-section of the mains cable supplied with
the unit.
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 condition. Take immediate action
to repair or replace damaged parts.
 Use genuine parts and accessories only. Unapproved parts may be
dangerous and will invalidate the warranty.
 Use an air hose to regularly blow out any dirt from the liner and keep
the welder clean for best and safest performance.
 Check and spray the gas cup and contact tip regularly with
anti-spatter spray which is available from your Sealey dealer.
 locate the welder in a suitable work area. ensure that the area has
adequate ventilation as welding fumes are harmful.
 Keep work area clean, tidy and free from unrelated materials. Also
ensure that the work area has adequate lighting and that a fire
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.
 ensure that the workpiece is correctly secured before operating the welder.
 Avoid unintentional contact with workpiece. Accidental or uncontrolled
use 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 protective head shield and gloves.
 Operators must receive adequate training before using the welder.
 Stand correctly, keeping a good footing and balance, and ensure that
the floor is not slippery. Wear non-slip shoes.
 Turn voltage switch to OFF when not in use.
 dO NOT operate the welder if it or its cables are damaged and dO
NOT attempt to fit any unapproved torch or other parts to the welder unit.
 dO NOT get welder wet or use in damp or wet locations or areas
where there is condensation.
 DANGER! DO NOT weld near inflammable materials, solids,
liquids, or gases, and 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 stand welder on a metal workbench, car bodywork or similar
object.
 dO NOT touch any live metal parts of the torch or electrode while the
machine is switched on.
 dO NOT pull the welder by the cable or the torch and dO NOT bend
or strain cables. Protect cables from sharp or abrasive items and dO
NOT stand on them. Protect from heat. long lengths of slack must be
gathered and neatly coiled. dO NOT place cables where they could
endanger other people.
 dO NOT touch the torch or workpiece immediately after welding as
they will be very hot. Allow to cool.
 dO NOT operate welder while under the influence of drugs, alcohol or
intoxicating medication, or if tired.
 When not in use store the welder in a safe, dry, childproof area.
1.3. GAS SAFETY
 Store gas cylinders in a vertical position only and ensure that the
storage area is correctly secured.
 dO NOT store gas cylinders in areas where temperature exceeds
50°C. dO NOT use direct heat on a cylinder. Always keep gas
cylinders cool.
 dO NOT attempt to repair or modify any part of a gas cylinder or valve
and dO NOT puncture or damage a cylinder.
 dO NOT obscure or remove any official cylinder labels. Always check
the gas identity before use. Avoid getting gas cylinders oily or greasy.

and guards in place and close valve when not in use.
2.1 INTRODUCTION: Our professional range of MIGHTYMIG welders all
feature a heavy-duty high output transformer and forced air cooling to
maximise duty cycle performance. MIGHTYMIG170, 190 and 210 are
supplied with a high quality cool running BINZel® euro torch thus
ensuring a steadier weld bead, 2mtr earth cable, 1.4mtr of gas hose, twin
guaged gas regulator, 1kg spool of 0.6mm wire, 0.6 and 0.8 tips. All three
units are supplied set up in gas mode, but can also easily be switched to
gasless mode by a simple change of polarity. Use in gasless mode will
require the purchase of a spool of flux cored wire, a pack of 1.0mm tips
and a 1.0mm wire feed roller.
2.2 IMPORTANT: These instructions contain information you require to
prepare your machine for welding, together with a maintenance and
trouble shooting section. If you have no previous experience the instructions
are not intended to show you how to become a welder . Should you have no
experience, we recommend that you seek training from an expert
source. MIG welding is relatively easy to perform, but does require a
steady hand and time practising under supervision with scrap metal
as it is only with continued practice that you will achieve the desired
results.
