PRINCIPLES OF THE MACHINE

The MIG120 Multi is an inverter type welding machine, suitable to carry out Gas and

No Gas CO2 welding, MMA, TIG and MIG (MAG -USA welding). The welder is mainly

used for CO2 gas protected welding which has the advantages of high energy

efficiency, strong arc penetration and small welding deformation.

Weldable materials include low carbon steel, low alloy steel, high strength steel,

stainless steel and aluminium alloy. Methods include full position spot welding, butt

welding, fillet welding and lap welding. The stable welding process can be obtained

by using pure CO2, CO2+Ar, CO2+ O2 and other protective gases. The torch is suitable

for wire diameters of 0.6-1.0mm.

Manual Metal Arc (MMA) welding uses a coated consumable electrode (stick) to lay

the weld, therefore an additional welding torch kit is not used. The arc melts the core

of the electrode to produce drops of molten metal (weld pool) that cool to create the

welded joint. Because of the versatility and simplicity of MMA welding, it requires less

skill and is used primarily to weld iron and steel (including stainless steel. but nickel

and copper can also be welded using this method.

MIG (Metal Inert Gas) welding allows you to fuse together two similar metals without

altering the properties of the metal.

A consumable wire electrode is continuously fed through the welding torch fitted with

a concentric gas nozzle. the wire is connected to a high voltage supply which creates

an electric arc between the electrode (the wire) and the workpiece. The arc is used to

create the required heat to turn the metal into a molten state. The wire is used as

both the electrode and as a filler.

The gas is used to prevent oxidation and to shield the arc and the weld from

atmospheric contamination. The choice of gas is dependent upon the material being

welded. This machine is designed to be used for both metal ARC (MMA) and TIG

welding.

(TIG torch kit is not supplied with the machine. This are however, is readily available

from your CLARKE dealer (Part number 6012232).

A wide selection of accessories and consumables are available from your CLARKE

dealer (see page 36)
