delivered by the welding machine.
X Duty cycle. Indicate how long the welding machine
can work for and how long it must rest for in order to
cool down. The time is expressed in % on the basis
of a 10 minute cycle (e.g. 60% means 6 min. work
and 4 min. rest).

Starting up
Assembly and electrical connections
¾Assembly the detached parts found in the packaging Fig.10.
¾Check that the electrical supply delivers the voltage and
frequency corresponding to the welding machine and that
it is fi tted with an automatic switch suited to the maximum
delivered rated current (I2max) Fig. 9,1.
The requirements set out in the IEC/EN61000-3-12 standard
L
do not apply to this equipment. If this equipment is connected
to low voltage power supply network, either the installer or
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.
The torches with speed controls on the handle and Spool
L
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.
Preparing the welding circuit MMA
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 cable with the electrode holder gripper** to the
welding machine and mount the electrode on the gripper.
Refer to the electrode manufacturer's instructions concerning
connection and welding current.
Preparing the welding circuit TIG
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 TIG torch** power connector to the negative
attachment on the welding machine and mount the electrode.
The torch must be fi tted with a gas fl ow adjustment valve.
¾ Connect the TIG torch gas pipe to the output of the pressure
reducer mounted on an ARGON protection gas cylinder.
The recommended sections (mm2) of the welding cable,
L
based on the maximum delivered rated current (I2 max),
are shown in Fig. 9,3.
