remove the roller, align the flat part of the roller-bearing
pin at the bottom, so the key can be fitted inside the
retention screw. Loosen the screw, remove the roller, fit
the roller back on so the race corresponds to the wire
used, see figures 3 and 4.
• Cut the wire with a well-sharpened tool, keeping it between
your fingers so that it cannot unwind, insert it inside the
plastic pipe exiting from the gear motor and, with the aid
of a finger, also insert it inside the steel tube until it comes
out of the brass adapter, see figures 5-6-7-8.
• Close the drive arm, being careful of the wire, which
must be aligned with the roller race, see fig. 9.
• Fit the welding torch.
After fitting 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 fit the gas nozzle.
Open the canister adapter and adjust the gas flow 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. 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.
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 flux 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 a suitable torch to the flux cored wire; because this
wire has no gaseous protection it heats up the end lance
much more.
Fit the wire roller suitable to the 0.9 mm diameter flux
cored wire and the current nozzle on the welding torch.
Connect the terminal of the earth lead, inside the
reel compartment, to the positive pole, while the lead
coming out of the dividing wall must be connected to
the negative pole.
Connect the earth lead clamp to the piece to be
welded.

release number of the synergic curves (this information is also
given in Section 7.1 SERVICE FUNCTIONS).
Immediately after switch-on, the display screen A shows:
The synergic curve used, the welding mode 2T, 4T or
3L, 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 val-
ues 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, briefly 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 confirm the choice by pressing
the knob B for less than 2 seconds.
When the machine is switched
on, for a few moments the
display screen A displays: the
