Remove ill fitting clothing, remove ties, watches, rings and other loose jewellery and contain long hair.
Ensure the workpiece is correctly secured before welding.
Avoid unintentional contact with the 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 a protective head shield and gloves.
Operators must receive adequate training before using the welder.
Stand correctly keeping a good footing and balance, ensure the floor is not slippery and wear non-slip shoes.
DO NOT
operate the welder if it or the cables are damaged and
DO NOT
attempt to fit any unapproved torches or other
components to the welder.
DO NOT
get welder wet or use in damp or wet locations or areas where there is condensation.
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.
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. Protect cables from sharp or abrasive items.
DO NOT
bend, strain or stand on cables
or leads. Protect from heat. Long lengths of slack must be gathered and neatly coiled.
DO NOT
place cables where they endanger
others.
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.
2. INTRODUCTION & SPECIFICATION
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.
INTRODUCTION:
Our professional range of MIGHTYMIG welders all feature a heavy-duty high output transformer and forced air cooling to
maximise duty cycle performance.
MIGHTYMIG90 is supplied with a comfort grip non-live torch, 2mtr earth cable, 0.2kg flux cored wire and 0.9mm contact tip.

3. PREPARATION
3.1. Fitting a reel of wire:
3.1.1. Push the lock button back to release the lid (fig.1)
3.1.2. Rotate the wing nut (fig.2.5) anti-clockwise and remove it from the threaded spindle together with the pressure disc (fig.2.4).
Leave the spring (fig.2.1) on the spindle (fig.2.2).
3.1.3. Place the wire reel (fig.2.3) over the spindle and down onto the spring ensuring that the wire will withdraw from the spool in a forwards
direction and on the same side of the compartment as the wire feed unit.
3.1.4. Push down lightly on the top of the reel of wire and screw the pressure disc (fig.2.4) onto the end of the spindle and down onto the top of
the wire reel. The reel take off pressure should be set to provide slight friction to prevent overrun where loose coils of wire form on
the reel.
DO NOT
overtighten the pressure disc. Lock the position of the pressure disc by screwing the wing nut (fig.2.5) down on top of it.
3.1.5. Turn the knob on the wire lock screw (fig.1.1) anti-clockwise and lift it up and away from the pressure roller bracket (fig.1.2). Swing
the pressure roller bracket away from the drive roller.
3.1.6. Release the wire from the spool (do not allow wire to uncoil) and straighten 40-50mm of wire and push gently through the flexible plastic
guide (fig.1.4) and through the 0.9mm groove in the feed roller (fig.1.3) and into the torch liner (fig.3).
3.1.7. Close the pressure roller bracket onto the grooved drive wheel and swing down the wire lock screw to lock it in place (fig.4). See section 3.2
regarding wire tension.
