the user is responsible for checking that this can be done
(consult the distribution system operator if required).
In order to comply with the requirements set out in the
L
EN61000-3-11 (Flicker) standard, it is advisable to connect
the welder to the supply network interface points having an
impedance lower than the reference Zmax = Fig.9,4.
Preparing the welding circuit MIG
¾Connect the ground lead to the welding machine and to the
piece to be welded, as close as possible to the point to be
welded.
¾Connect the torch** to the welding machine socket.
¾In welding machines with external wire feeders, connect the
power and control cables to the sockets on the generator
and trolley.
The external wire feeder is designed for use only and
exclusively togheter with the specifi c welding machi-
ne; indipendent use is prohibited.

The torches with speed controls on the handle and Spool

guns have a pin that must be connected in the socket G
Fig. 1.
Installing the continuous wire
For installation, follow the instructions in Fig. 3.
The material and diameter of the wire must correspond to
the wire feeder roller, the contact tip and the torch liner. If the
measurements do not match, there may be problems with the
smooth running of the wire.
The pressure of the wire pressing knob is important for correct
L
operation. If the wire slips, there will be problems with the
welding; if on the other hand it is too tight, it may be deformed
and will not run smoothly through the torch.
Wire load function
Press the button "Q" inside the coil compartment and then the
button on the torch. The wire is loaded even after releasing the
button "Q" until the button on the torch is pressed.
Installing the protective gas cylinder** and pressure
reducer**
„ Place the protective gas cylinder in an upright position, far
away from the welding area. Use the welding machine support
or some other fi xed part so that there is no risk of it falling or
being damaged.
For installation, follow the instructions in Fig. 4.
Gas test function
Press the button "P" inside the coil compartment. The
solenoid valve remains open until the button is pressed again,
or it will close automatically after 30 seconds.
