1 INTRODUCTION
The welding machines is manufactured with advanced
inverter technology and is suitable for MIG/MAG/MOG
welding. It’ s highly reliable, handy and compact. It can
automatically manage many functions that allow the
good result of the welding. This equipment must be
used ONLY for welding operations.
2 HOW TO PUT THE MACHINE ON
Before using the welding machine, read and understand
the safety manual enclosed to this user manual.
The machine must be set by skilled and qualified staff
who will have to make all the necessary connections
according to the safety regulations in force.
The staff must follow the health and safety norms, and
the instructions given from manufacturers.
Make sure that the supply voltage corresponds to the
value indicated on the technical data’s label on the
welding machine. The plug of power cord must be insert
in an electrical socket 1ph with an earth and protected
with fuses or automatic power switches adequate to the
absorbed current I1 from the machine. For the models
without plug, connect the plug of adequate capacity to
the power cord making sure that the conductor of
yellow/green colour is correctly connected to the earth
socket. The machine has an IP 21 protection level - it
must not be used or stored under the rain!
To put the machine on, it has to be equipped with the
accessories included.
The operations to carry out are according the model:
-Wire spool housing
-Torch assembly
-Handle assembly
2.1 WELDING MACHINE WITH PFC DEVICE
(OPTIONAL)
PFC device reduces the disturbances in the power net,
reduces the electricity consumption and allows a better
compatibility to power generator. The welding machines
equipped with PFC device are conform to IEC61000-3-
12 norm that means they are connectable to public low-
voltage power net. For models not equipped with PFC
device and not conform to IEC61000-3-12 norm, it is
responsibility of the installer or the end user to assure,
after consulting the manager of the net distribution, if
necessary, that the welding machine can be connected
to the public low-voltage power net.
2.2 WIRE FEEDER MOTOR
Make sure that the size of the groove in the wire
feeding roll corresponds to the size of the welding wire
being used. The machines are arranged with a feed roll
for Ø 0,6mm (0,025in) and Ø 0,8mm (0,030in) wire. In
case you want to use Ø 1mm (0,040in) welding wire,
ask for the suitable feeding roll. The feeding roll has the
wire diameter stamped on its side.
2.3 HOW TO ASSEMBLE THE TORCH
The torch is already assembled on the models having
direct connection. For models with EURO connector,
connect the MIG torch like in picture nr 10.
2.4 HANDLE ASSEMBLY
Assemble the handle on the welding machine mantle
like in picture nr 9.
Make sure of the correct tightening of the screws and of
the held of handle before lift the machine.
3 WELDING MACHINE FUNCTIONING
CONTROL DEVICE
It is recommended to place the machine in a well-
ventilated area, possibly in the shade and free from
obstacles that may avoid the air intake through the
cooling fans. Absence of ventilation causes the
overheating of the internal components. Do not leave
the equipment under the sun during welding operations,
do not cover it with towels or other material that may
prevent air from circulating.
3.1 FRONT PANEL SETTING
It’s possible to regulate the welding functions through
the control panel placed on the bottom of front panel fig.
6.
On the panel there is a display DISP and 2 knobs ENC-
1 and ENC-2. The display shows the set speed of the
wire. Turning ENC-1, it is possible to change the value
of the speed wire. It is expressed in mt/min (12.5
means 12.5 mt per minute). Rotating ENC-2, it is
possible to change the value of the power.
WARNING
!
If the power is set and the knob is not moved within 3
seconds, the display will show again the set speed
value.
3.2 MIG TORCH USE
Welding with the MIG torch, push the trigger “c” (fig. 7)
after having connected the earth clamp to the negative
outlet.
3.3 GAS WELDING
To weld with wire gas you need to protect the melt dip.
Usually, the gas to be used is a mix of Argon and CO2,
pure Argon or pure CO2. The argon one is employed
for the welding of aluminium while others are used for
the welding of ferrous material.
3.4 NO GAS WELDING
The use of gas can be avoided if you use flux cored
wire. This kind of wire emits gas which creates a
protective environment for the welding. To use function
NO GAS, you need to invert the connections like in
picture 8.

The two processes are exactly the same, what changes
is the gas used. In MIG case, the gas employed (inert
gas) is ARGON. In MAG case, the gas employed (
active gas) is CO2. To weld aluminium alloys you need
