• P osition the cylinder on the support and fix it with the 2
straps; ensure that the straps are secured tightly to the
cylinder to prevent dangerous tilting.
• Connect the gas hose to the outlet of the pressure regulator.
• Open the side door.
Make sure the earth lead D, inside the reel
compartment, is connected to the negative pole see
the instruction plate placed alongside the + and -
terminals).
• Connect the earth lead clamp D to the piece to be welded.
• Fit the wire coil on the support inside the compartment.
The coil must be fitted so that the wire unwinds in an
anticlockwise direction.
• Make sure the drive roller is correctly positioned according
to the diameter and type of wire used.
• Cut the welding wire with a well-sharpened tool, keeping
it between your fingers so that it cannot unwind, insert it
inside the pipe exiting from the gear motor and, with the
aid of a finger, insert it inside the steel tube until it comes
out of the adapter.
• 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, 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 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 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.
7 DESCRIPTION OF FUNCTIONS SHOWN ON THE
DISPLAY SCREEN A.
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
When the machine is switched
on, for a few moments the
display screen A displays: the
