Make sure that the supply voltage corresponds to the rated
voltage of the welding machine.
Size the protective fuses based on the data listed on the
technical specifications plate.
Connect the gas hose of the welding machine to the pressure
regulator of the cylinder.
Mount the MIG torch on the fitting
C .
Connect the earth cable to the socket D and the earth clamp
to the workpiece. Make sure that the groove of the rollers
matches the wire diameter used.
To replace if necessary: open the side door, mount the wire
coil and slip the wire into the feeder and torch sheath, block
the wire press rollers with the knob and adjust the pressure.
Turn on the machine.
Select the suitable synergic curve, following the instructions
given in the service functions (
PROCESS PARAMS )
paragraph. Remove the gas nozzle and unscrew the current
nozzle of the torch. Press the torch button until the wire comes
out.
BE CAREFUL to keep your face away from the end
lance while the wire is coming out , screw up the current
nozzle and fit the gas nozzle.
Open the canister adapter and adjust the gas flow to 8 – 10
l/min.
During welding, the display screen
B displays the actual work
current and voltage.
The displayed values may be slightly different to those set.
This can depend on numerous different factors - type of torch,
thickness different to nominal thickness, distance between
current nozzle and the material being welded, and the welding
speed.
After welding, the current and voltage values remain stored on
the display
B , where the word HOLD is displayed.
To display the set values, the knob A will have to be moved
slightly, while, by pushing the torch button without welding, the
display screen
B shows the empty voltage value and a current
value of 0.
If, while welding the maximum current and voltage values are
exceeded, said values are not stored on the display and the
word HOLD is not displayed.
NOTE If 0.6mm diameter wires are used the welding torch
sheath should be replaced with one of suitable internal
diameter.
If the internal diameter of the sheath is too big it does not
guarantee smooth wire feeding.
6 DESCRIPTION OF FUNCTIONS SHOWN ON THE
DISPLAY SCREEN B.
When the machine is switched on, for a few moments the
display screen
B displays: the article number of the machine,
the version and development date of the software, and the
release number of the synergic curves.
Immediately after switch-on, the display screen
B shows: the
synergic curve used, the welding mode 2T or 4T , SPOT
function, if active, the welding process " SHORT or PULSED
(optional)", the welding current, the speed of the welding wire
in metres/min, the welding voltage and the recommended
thickness.
To increase or decrease the welding parameters, simply
adjust by means of knob
A . The values all change together in
a synergic way.
To change the welding voltage V, simply press the knob A for
less than 2 seconds. The display screen will show ( Arc
Length ) an adjustment bar with central 0. The value can be
changed by means of the knob A from -9.9 to 9.9. To exit from
the function, briefly press the knob A.
6.1 SERVICE FUNCTIONS (PROCESS PARAMS) SHOWN
ON THE DISPLAY SCREEN B.
To access these functions, we must start from the main
display page and press the knob
A for at least 2 seconds.
To enter the function, simply select it by means of the knob A
and press it for less than 2 seconds.
To return to the main display page, press the knob
A for at
least 2 seconds.
The functions that can be selected are:

Synergic curve (Wire Selection).
To choose the synergic curve, by means of the knob A , it
is necessary to select and press on the curve presented by
the display screen
B . Simply select the curve of interest
and confirm the choice by pressing the knob A for less
than 2 seconds.
After pressing the knob
A return is made to the previous
display page ( PROCESS PARAMS ).

Process
Use knob A to choose or confirm a welding mode by
selecting and pressing Short or Pulsed (optional) for less
than 2 seconds.
Short indicates that the short synergic welding mode is
selected.
Pulsed indicates that the pulsed synergic welding mode is
selected.

Welding mode (Start Mode).
Mode 2T , the machine starts welding when the torch
button is pressed and stops when this is released. Mode
4T , to start welding, press and release the torch button. To
complete welding, press and release again. To choose the
welding start mode
2T or 4T, select one of the 2 modes by
means of the knob A and press the knob A for less than 2
seconds to confirm the choice. This operation always
returns us to the previous display page (
PROCESS
PARAMS ).

Spot and pause time (Spot).
If we select the spot ON time, the Spot Time function
appears on the display screen. If we select this, we can
adjust it from 0.3 to 25 seconds by means of the
