• Fit the welding torch.
After fi tting the reel and torch, switch 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 fi t the gas nozzle.
Open the canister adapter and adjust the gas fl ow to 8 –
10 l/min.
During welding, the display screen A 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 A, where letter H (HOLD) is
displayed. To display the set values, the handle B will
have to be moved slightly, while, by pushing the torch
button without welding, the display screen A shows the
empty voltage value and a current value of 0.
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 INSTALLATION AND START UP FOR WELDING
WITHOUT GAS.
The operations for preparing the machine for welding are
the same as those previously described, but for this type
of welding, proceed as follows:
Fit a reel of fl ux cored wire for welding without gas and
select the adequate synergic curve (E71TGS 0.9mm),
following the instructions described in the "service
functions (PROCESS PARAMS) paragraph.
Fit on the welding torch the wire feed roller and the
contact tip adequate for the lux-cored wire of 0.9 mm
diameter
Connect the terminal of the earth lead, inside the reel
compartment, to the positive pole (see the instruction
plate placed alongside the + and - terminals).
Connect the earth lead clamp to the piece to be
welded.

When the machine is switched
on, for a few moments the
display screen A displays: the
article number of the machine,
the version and development
date of the software, and the
Immediately after switch-on, the display screen A shows:
The synergic curve used, the welding mode 2T or 4T,
SPOT function, if active, the letters PP if a push-pull
welding torch is used, the welding process "SHORT or
PULSED", the welding current, the speed of the welding
wire in metres/min, the welding voltage and the recom-
mended thickness.
To increase or decrease the welding parameters, simply
adjust by means of knob B. The values all change together
in a synergic way.
To change the welding voltage V, simply press the knob B
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 B from -9.9 to 9.9. To
exit from the function, briefl y press the knob B.
By changing the value, once having exited the sub-menu,
alongside the voltage V, an arrow will appear turned
upwards to indicate a higher adjustment of the set value,
while the arrow turned downwards will indicate a lower
adjustment.
7.1 SERVICE FUNCTIONS
SHOWN ON THE DISPLAY SCREEN A.
To access these functions, we must start from the main
display page and press the knob B for at least 2 seconds.
To enter the function, simply select it by means of the
knob B and press it for less than 2 seconds. To return
to the main display page, press the knob B for at least 2
seconds.
The functions which can be selected are:
• Synergic curve (Wire Selection).
To choose the synergic curve, by means of the knob
B, it is necessary to select and press on the curve
presented by the display screen A. Simply select the
curve of interest and confi rm the choice by pressing
the knob B for less than 2 seconds.
After pressing the knob B return is made to the previous
display page (PROCESS PARAMS).
