Turn the knob Y to select the type of operation:
OFF = Off
Adjustment range = 5 –50cm.
4 WELDING
4.1 SETUP
Position the wire feeder on the power source.
Connect the wire feeder to the power source via the appropriate
extension.
NOTE: avoid coiling the connection to reduce to a minimum the
inductive effects that could affect the results in pulsed MIG/MAG
welding. Connect the gas hose to the pressure regulator output.
Assemble the torch. Make sure that the groove of the rollers
matches the wire diameter used.
Mount the wire coil and slip the wire into the feeder and torch
sheath.
Turn on the machine. Adjust the gas using the key Z, then move
the wire forward using the key V2.
If a water-cooled torch is used, set the operation of the cooling
unit as described in paragraph 3.2.2.5.1 of the control panel
manual.
4.2 SYNERGIC PULSED MIG (LED B1)
OR SYNERGIC NON-PULSED MIG WELDING (LED C1)
Select this process via the button A1.
Then choose the mode, wire diameter, type and quality of the
material and the type of gas.
Adjust the accessory functions according to the instructions in
paragraph 3.2.2.
Adjust the welding parameters using the knobs X and Y.
4.3 CONVENTIONAL MIG WELDING (LED D1)
Select this process via the button A1.
Then choose the mode, wire diameter, type and quality of the
material and the type of gas.
Adjust the accessory functions following the instructions in
paragraph 3.2.2 of the control panel manual.
Adjust the wire speed and the welding voltage, respectively,
using the knobs X and Y.
4.4 TIG WELDING (LED E1)
Connect the earth cable to the positive pole M and the connector
of the trolley/power source connection power cable to the
negative pole F.
Connect the TIG torch to the connector B.
Select this process via the button A1.
Then choose the mode via the button G1.
Adjust the accessory functions following the instructions in
paragraph 3.2.2 of the control panel manual.
4.5 MMA WELDING (LED F1)
NOTE: the wire feeder must remain connected to the power
source.
Connect the connectors of the electrode holder and earth cable
to the connectors F and M, observing the polarity stated by the
electrode manufacturer.
5 MAINTAINING THE SYSTEM
• Shielding gas nozzle
This nozzle must be periodically cleaned to remove weld spatter.
Replace if distorted or squashed.
• Contact tip.
Only a good contact between this contact tip and the wire can
ensure a stable arc and optimum current output; you must
therefore observe the following precautions:
A) The contact tip hole must be kept free of grime and oxidation
(rust).
B) Weld spatter sticks more easily after long welding sessions,
blocking the wire flow.
The tip must therefore be cleaned more often, and replaced
if necessary.
C) The contact tip must always be firmly screwed onto the torch
body. The thermal cycles to which the torch is subjected can
cause it to loosen, thus heating the torch body and tip and
causing the wire to advance unevenly.
• Wire liner.
This is an important part that must be checked often, because
the wire may deposit copper dust or tiny shavings. Clean it
periodically along with the gas lines, using dry compressed air.
The liners are subjected to constant wear and tear, and
therefore must be replaced after a certain amount of time.
• Gearmotor group.
Periodically clean the set of feeder rollers, to remove any rust or
metal residue left by the coils. You must periodically check the
entire wire feeder group: hasp, wire guide rollers, liner and
contact tip.
6 ACCESSORIES
6.1 TIG torch item 535718
TIG torch type, uncooled, 4m.
6.2 MIG torch item 535019 (only for item 312)
MIG torch type MB 501D water-cooled, 3 m
6.3 MIG torch item 535030 (only for item 314)
MIG torch type MIG 500A, water-cooled, 3,5 m
6.4 MIG torch item 535031 (with double control U/D)
MIG torch type MIG 500A, water-cooled, 3,5 m, with double

The left U/D command:
- in synergic programs, adjusts the welding parameters along
the synergic curve,
- in conventional MIG, adjusts the wire speed,
- within saved programs, selects them numerically.
If you intend to save with the U/D torch inserted (LED Y2 lit), you
may choose the program number via the U/D button.
The right U/D command:
- in synergic programs, adjusts the arc length,
- in conventional MIG, adjusts the voltage,
- not active within saved programs.
When the U/D torch connector is inserted, the LED X2 lights to
indicate that the torch has been recognized.
6.5 Kit for welding with push-pull torches.
Installing this optional board makes it possible to use push-pull
torches with the torch motor at 42V.
