Installation; System Presentation; General; Front Control Panel (Neomig 1600-2000-2200-2400) - Selco Neomig 1600 Instrucciones De Uso

Verify the existence of the earthing in the equipment used
and the good condition of the sockets.
Install only certified plugs according to the safety regula-
tions.

2.4 Installation

Connection for MIG/MAG welding
- Disconnect the power supply from the power source.
- Connect the MIG torch to the central adapter (1), ensuring
that the fastening ring is fully tightened.
- 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-
button.
- Connect the gas hose to the rear gas hose coupling.
- Adjust the gas flow from 5 to 20 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
(Neomig 1600-2000-2200-2400)
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 Off/On switch
Turns on the electric power to the welder.
It has two positions, "O" off, and "I" on.
5 Secondary power selector switch
Switch for adjustment with up to 7/10 positions.
For both switches, the output voltage increases with the
position number.
Never touch the switch while you are welding!
6 Main adjustment handle
Allows continuous adjustment of the wire feed speed.
7 Welding methods
2 Step
In two step, pressing the button causes the gas to flow,
feeds voltage to the wire and makes it advance; when
it is released, the gas, the voltage and the wire feed are
turned off.
4 Step
In four step first pressure on the button causes the gas
to flow with a manual pre-gas time; releasing it activates
the voltage to the wire and its feed.
The following pressure on the button stops the wire and
causes the final process to start which brings the current
back to zero; finally releasing the button turns off the
gas flow.
Spot welding
It allows performing timed welding.
