a ‘V’ cable are suitable for feeding iron and
steel wire. The spools with a ‘U’ are suitable for
aluminium wire.
4. MIG/MAG WELDING To choose this welding
mode use switch 10, select MIG and press
confirm.
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.
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 fluxcovered 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:

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.
