2.3 Connection
The SELCO mobile units are powered exclusively at low voltage.
2.4 Installation
Connection for MIG/MAG welding
- Disconnect the power supply from the power source.
- Connect the power cable to the appropriate outlet (1).
Insert the plug and turn clockwise until all parts are secured.
- Connect the signal cable to the appropriate connector (2).
Insert the connector and screw the ring nut clockwise until all
parts are secured.
- Connect the gas hose to the pressure reducing valve of the
cylinder or to the gas supply connection (3).
- Connect the water pipe (blue colored
quick connector of the cooling unit (4).
- Connect the water pipe (red colored
connector of the cooling unit (5).
- Connect the red colored
inlet quick connector of the cooling unit (6).
- Connect the blue colored
outlet quick connector of the cooling unit (7).
- Connect the MIG torch to the central adapter (8), 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 (9) from the spindle and insert the wire spool.
Insert also the spool pin, insert the spool, reposition the ring
nut (9) and adjust the friction screw (10).
- Release the rolls lever of the wire feeder (11), 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 10 to 14 l/min.
3 SYSTEM PRESENTATION
3.1 General
The semiautomatic UNISTEP 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 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.
5 Main adjustment handle.
Allows wire speed adjustment in manual MIG welding
and synergy correction in synergic MIG welding .
