PRINCIPLES OF THE MACHINE
The MIG120 Multi is an inverter type welding machine, suitable to carry out
Gas and No Gas CO
2
welding, MMA, TIG and MIG (MAG -USA welding). The
welder is mainly used for CO
2
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 CO
2
, CO
2
+Ar, CO
2
+ O
2
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 welding leads are not supplied with the machine. These are however,
readily available from your CLARKE dealer (Part number 6012233).
A wide selection of accessories and consumables are available from your
CLARKE dealer (see page 36)
