- "Consult the "Installation kit/accessories" section".
- Connect the red colored
inlet quick connector of the cooling unit.
- Connect the blue colored
outlet quick connector of the cooling unit.
- Connect the MIG torch (7) to the central adapter (8), ensuring
that the fastening ring is fully tightened.
- Connect (9) the earth clamp to the negative socket (-) (10) of
the power source.
- Open the right side cover.
- Check that the roller groove is consistent with the diameter of
the wire you wish to use.
- Unscrew the ring nut (11) from the spindle and insert the wire
spool.
Insert also the spool pin, insert the spool, reposition the ring
nut (11) and adjust the friction screw (12).
- Release the rolls lever of the wire feeder (13), sliding the end
of the wire into the wire guide bush and, passing it over the
roller, into the torch fitting. Lock the feed support in position,
checking that the wire has entered the roller groove.
- To load the wire onto the torch, press the wire feed push-
button.
- Adjust the gas flow from 5 to 20 l/min.

3 SYSTEM PRESENTATION

3.1 General

The wire feed unit WF 4000 is the mobile part of a complete
MIG/MAG welding system which uses the URANOS 3200 GSM,
PME, MSE generators.
It is connected to the generator by a bundle of cables of variable
length. The unit is extremely compact with the "coil" compart-
ment fully protected from dust, chips, etc., and electrically
insulated.
The wire feed is provided by a 120W robust motor with 2/4
rollers controlled by an optical encoder.
The presence of a powerful microprocessor allows full control
of all the welding functions, making this system suitable for vari-
ous types of welding process such as MIG/MAG, Pulsed-MIG,
Double Pulsed-MIG.

1 VRD Voltage Reduction Device
Shows that the no-load voltage of the equipment is
controlled.
2 General alarm
Indicates the possible intervention of protection devices
such as the temperature protection.
3 Power on
Indicates the presence of voltage on the equipment
outlet connections.
4 7-segment display
