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.
- 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-button.
- Connect the gas hose on the rear gas hose coupling.
- Adjust the gas flow from 10 to 14 l/min.

3 SYSTEM PRESENTATION

3.1 Generalities

The semiautomatic HARRIER series systems for continuous wire
welding in MIG/MAG ensure high performance and quality in
welding with solid and core wires.
The HARRIER series, characterised by the incorporated wire
feed unit, provide "compact" power sources which are easy to
move and feature limited dimensions.
The HARRIER power sources are able to meet all welding
requirements.
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.
The wire feed speed can be adjusted directly from the front
panel via potentiometer.

3.2 Front control panel

1: switch. The main sparking switch (Pos. 0 = power source
OFF).
1A: switch.
Switch for sparking and the adjustment of the main fields
at 2/3 positions. When not set in 0, the switch connects
power to the equipment (pos. 0 = power source OFF).
2: switch.
Switch for fine adjustment to 10 positions.
The output voltage increases as the number of the posi-
tion increases.
Never operate the switch while you are welding!
3: comes on as soon as the power source is powered.
4: indicates cut-in of any protection devices such as the
thermal protection.
