To choose this welding mode use switch
10, select MIG and press confirm.
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,
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
