(180mm - 7.1in) and height
MAX
(1000mm - 39.4in) or
only 1 cylinder having diameter
MAX
(220mm – 8.7in)
and height MAX (1600mm – 63in). The cylinders must be
firmly fixed to the cylinder shelf by means of the belts
provided.
The gas cylinder must be equipped with a pressure reg-
ulator and a gauge.
Only after positioning the cylinder, connect the outgoing
gas hose from the rear panel of the machine to the pres-
sure regulator.
Open the mobile lateral side, mount the wire coil on its
support, insert the wire coming out of the wire coil into
the gear motor, and make sure that wire type and diam-
eter are the same as drive roller ones. The wire must be
aligned with the roller race and come out of the adapter
C
. Close the drive arm, fit the welding torch and the earth
cable on socket
D
.
After fitting the reel and torch, switch on the machine,
select the synergic curve suitable to the type of wire to
be welded, 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 DESCRIPTION OF FUNCTIONS SHOWN
ON THE DISPLAY SCREEN A.
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
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

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
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, 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.
