MIG WELDING PRINCIPLES
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
that is 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, Two types are available from Clarke International.
When using the welder in a gasless configuration the shielding gas is created
from the flux within the welding wire.
When using the welder outside, you may need to erect a wind break to make
sure the shielding gas is not blown away, thereby leaving a poor quality weld.
GAS/NO-GAS SELECTION
The welder can be configured to
weld, with or without a gas supply
according to the type of welding
wire being used.
