with current standards and in full observance of cur-
rent safety laws.
3.1 Installation (fig. 2).
Place the Wire Feeder in the housing provided on the
Robot arm.
Install the torch (7) on the Robot arm and connect
it to the Wire Feeder (8), including any pipes of the
cooling circuit.
Connect the Power Source (21) to the Wire Feeder
(8) by means of the extension (2).
NOTE: avoid coiling the extension (2) to reduce
to a minimum the inductive effects that
could affect the results in pulsed MIG/
MAG welding.
Make sure that the wire diameter matches the diam-
eter shown on the roller. To eventually replace the
rollers follow the procedure in par. 3.2.
Mount the wire coil (6) and insert the wire in sheath
(10) into the wire feeder group inside the Wire Feeder
(8) and in the torch sheath (7). Make sure the welding
wire passes through the roller groove.
Block the wire press rollers with the knobs A and
adjust the pressure.
Before connecting the Power Source power cord,
make sure the mains voltage matches that of the
Power Source and that the earth socket is in good
working order.
Power up the Welding System using the mains
switch of the Power Source (see Power Source In-
struction Manual).
Remove the tapered gas nozzle from the torch.
Unscrew the contact tip.
Press the "Wire Test" key on the Control Panel (24)
and release it only when the wire emerges.
CAUTION!! Welding wire may cause puncture
wounds. Never aim the torch at parts
of the body when mounting the welding
electrode.
Screw the contact tip back on, making sure that the
hole diameter is the same as that of the wire used.
Replace the tapered gas nozzle.
Adjust the gas flow using the "Gas Test" key on the
Control Panel (24) and the flow regulator on the gas
cylinder.
3.2 Replacing the rollers (Fig. 3).
Unblock and raise the pressure regulation A knobs;
the wire press rollers B lifts;
Unscrew the stoppers C, open the cover D and re-
move the rollers E.
Insert the new rollers and perform the described op-
erations in reverse way.

4 WIRE FEEDER DESCRIPTION.
The Wire Feeder does not work independently, but
must be connected to the Power Source, with which
it communicates and from which it receives the sup-
ply voltage.
The equipment may be used only for the purposes
described in this manual.
