OPERATING THE WELDER (MIG)

1. With the welding current set and the wire trimmed, set the wire feed control to an

intermediate setting.

2. Plug the machine into the power supply and switch on.

3. Cover your face with the welding mask supplied.

4. Approach the work with the torch tip at an angle of about 45o and pull the torch

trigger fully.

• As the wire touches the workpiece an arc will be struck.

5. In order to produce a satisfactory weld, the control may be fine tuned as required.

This will come with practice.

• MIG welding is an acquired skill. It is strongly advised that, if you are not fully

familiar with this type of welding, you practice on a piece of material with the

same characteristics as your workpiece until you are satisfied with the result and

you have set your welder to produce a satisfactory weld.

• One of the problems experienced with novice welders is the welding wire sticking

to the contact tip. This is as a result of the wire feed speed being too slow. It is

always better therefore to start with too high a speed and back off slightly to

avoid the possibility of the wire welding itself to the tip.

• The speed of wire delivery will increase automatically as the current is increased.

• Listen to the sound made. An irregular crackling sound denotes too high a wire

speed. Decrease the voltage/speed until a regular, strong buzzing sound is heard.

WELDING TECHNIQUE

• Try to maintain the tip of the nozzle at an angle of approx 45oand at a constant

distance of approx 5-7mm from the workpiece.

• Try to maintain a constant speed of movement with the torch.

WARNING: WHEN WELDING ALWAYS ENSURE THERE IS ADEQUATE

VENTILATION IN THE WORK AREA DUE TO TOXIC FUMES.

WARNING: DO NOT STRIKE THE ELECTRODE ON THE WORKPIECE,

AS THIS MAY DAMAGE THE ELECTRODE.

WARNING: WELDING ARCS PRODUCE HARMFUL UV/IR LIGHT

WHICH CAN SERIOUSLY DAMAGE YOUR EYES. ALWAYS USE A

WELDING FACE-SHIELD WITH A SUITABLE FILTER THAT CONFORMS

TO CURRENT STANDARDS.

WARNING: PROTECT BYSTANDERS BY USING WELDING SCREENS.
