At this point, you are ready to begin welding.
Turn the welder on and ensure that your
workpiece is clean of rust or dirt and attach the
clamp to it. Make sure that the gas regulator is
attached to your bottle if necessary and turn it
anti-clockwise to meet the demands of your weld
whilst pressing the torch trigger. The current will
need to be adjusted as you are welding to find
the correct variables to match your wire feed
speed.
OPERATION
To begin MIG welding, you must first connect your welder up to a 230V supply using
the plug provided and plug the torch in to the torch connection on front panel. The
first image below shows where the input is for the mains supply.
Next, you will need to install the welding wire if applicable, to do this, you must lift
the side panel and locate the wire feed motor. The wire size needed will depend on
your workpiece but you will need the corresponding roller and tips for the wire size
fitted, e.g. a 1mm roller, lining and tips will be used with 1mm wire. To fit the wire,
you put the wire feed reel on the hub of the motor and tighten it accordingly. Once
this has been done, you can push the wire through the rollers and then the lining,
ensuring it is not too tight (if the wire is too tight between the rollers it can snag and
stop feeding/cause too much resistance on the motor) and press the trigger on the
torch for it to start feeding. The wire should be fed through until it comes through
the nozzle by a few cm. Then the correct size tip can be screwed onto the nozzle.
The above listed techniques are both adequate for welding depending on your workpiece.
The image to the right shows a few
types of welding techniques that are
administered when MIG welding.
The pushing weld is when the torch is
angled against the direction of the
weld.
The pulling weld is when your torch is
angled towards the direction of the
weld.
