SAFETY EQUIPMENT

A comprehensive range of CLARKE safety equipment for use when

welding is available from your local dealer.

MIG WELDING - PRINCIPLES OF OPERATION

MIG (Metal Inert Gas) welding is a process in which a power wire electrode

is fed continuously into the weld pool at a controlled, constant rate.

The wire is connected to the positive side of a rectified voltage supply. The

workpiece is connected to the negative side of the supply.

When the wire is fed, it comes into contact with the workpiece and an arc

is struck. The arc melts the wire and the material, fusing it together.

The wire, which is fed by the wire feed motor is fed into the weld pool,

burning itself off at a rate dependent upon the selected wire feed speed.

To protect the weld pool from oxidation and impurities during the welding

process, a shielding gas flows over and around the weld pool. This gas flow

must be sufficient to protect the weld, but not wasteful.

NOTE:

Poor gas coverage will result in poor welding. Excessive gas

coverage is wasteful and expensive

GAS/NO GAS

The ‘EN’ models are capable of welding with or without gas, so-called

‘Gas/No Gas’. It is MOST IMPORTANT that the operator reads the notes on

page 19 before attempting to use this welding technique.

BENEFITS OF MIG WELDING

1. 50% faster welding time.

2. Operator training time kept to a minimum.

3. There is no slag removal, thus eliminating almost all post-welding

cleaning operations.

4. Minimum waste of welding consumables.

5. Overall, a faster more efficient way of getting the job done.

6. Less heat - less distortion.

7. Ability to weld thin material.
