2.4 Installation

Connection for MIG/MAG welding
- Connect the MIG torch to the central adapter (1), ensuring
that the fastening ring is fully tightened.
- Connect the red colored
inlet quick connector of the cooling unit (5).
- Connect the blue colored
outlet quick connector of the cooling unit (6).
- 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 (2) from the spindle and insert the wire
spool.
Insert also the spool pin, insert the spool, reposition the ring
nut (2) and adjust the friction screw (3).
- Release the rolls lever of the wire feeder (4), 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-but-
ton.
- Connect the gas hose to the rear gas hose coupling.
- Adjust the gas flow from 10 to 15 l/min.

3 SYSTEM PRESENTATION

3.1 General

The semiautomatic NEOMIG Series systems for continuous wire
welding in MIG/MAG ensure high performance and quality in
welding with solid and core wires.
The static characteristic of the power source is constant voltage
with step adjustment of the welding voltage; the different
inductance outputs that can be selected enable the operator to
set optimal power source dynamics for welding.
These welding power sources feature an innovative "SYNERGY"
operating mode.
Synergy enable with setting of the type of material to be welded
and diameter of the wire used permits automatic wire speed
definition, simplifying system welding adjustment operations.

3.2 Front control panel

1 Power supply
Indicates that the equipment is connected to the mains
and is on.
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 Primary power selector switch
Switch with 3 positions for switching on and adjustment
of the principal ranges. In a position other than 0 the
equipment power supply is on (pos. 0 = power source
off).
Never touch the switch while you are welding!
5 Secondary power selector switch
Switch for adjustment with up to 10 positions.
For both switches, the output voltage increases with the
position number.
Never touch the switch while you are welding!
6 7-segment display
Allows the general welding machine parameters to be
displayed during start-up, settings, current and voltage
readings, while welding, and encoding of the alarms.
