MIG/MAG welding (Metal Inert Gas and Metal Active Gas) is
continuous wire feed welding that provides a higher current density
compared to welding with a flux covered electrode; this allows
increased penetration and speed and the joint can be filled with
less strokes. Welding is carried out by melting a metallic electrode,
consisting of a continuous wire, in a welding pool at a constant
speed, controlled by the welding torch. When the wire starts to feed,
it touches the area that requires welding, creating an electric arc; the
arc melts the wire, which is then deposited on the workpiece.
This welder can be used with the following types of wire:
1. Solid wire: must always be used with a gas shield.
2. Flux cored for gas welding: the centre of the wire contains a
mineral product that improves the quality of the weld (this must
always be used with gas).
The correct method for connecting the torch and the earth cable can
be seen in the table below:
Switch 9 adjusts the machine power. There are three principal MIG-
MAG welding modes:
1.Manual short arc
2.Synergic short arc
3.Pulsed arc synergic
4.1 Manual Short Arc MIG Welding
By turning switch 10 it is possible to choose from the
different MIG-MAG welding modes; press the switch to
select the desired option.
Once selected the follow screen will appear:
Wire speed: This sets the speed of the welding wire.
The welding current and the wire speed must be
adjusted, taking into consideration the thickness of
the workpiece. Larger pieces will require a higher
wire speed. For best results, the wire speed must be
adjusted during welding.
soft-start: This adjusts the contact speed of the wire,
