OPERATING THE WELDER

PREPARING THE WORKPIECE

The area being welded should be perfectly clean. Any coating, plating or

corrosion must be removed, otherwise a good weld will be impossible to

achieve.

Attach the earth clamp to the workpiece as close to the point of weld as

possible, without it being intrusive.

OPERATION

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

control to 6.

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

3. Cover your face with a welding mask or welding helmet.

•

This is essential.

4. Lower the torch to the workpiece with one hand and approach the work

with the torch tip at an angle of about 35o 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 controls may be fine tuned as

required. This will come with practice.

NOTE: 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 fine tuned your

welder to produce a satisfactory weld.

NOTE: 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. This is the reason

position 6 is recommended for start up.

NOTE: The Wire Feed control is for fine tuning the wire speed. The speed

of wire delivery will increase automatically as the current is
