4. POWER CONNECTOR
Before connecting the machine check the tension,
number of phases and the power supply frequency.
The admissible power supply is indicated in the
'Specific Techniques' section on page 5 of this
manual and on the information plate on the machine.
Check that the earth of the welder has been
connected correctly.
Furthermore, make sure that the plug provided with
the equipment is compatible with the local grid
sockets. Make sure that the power supply provides
sufficient power for the machine to function (tension
ranges) The power supply grid protection devices to
be used are listed in the 'Specific techniques'
section of the present manual. The machine is
provided with a specific power cable that does not
usually require an extension lead; in the event an
extension lead is required, use one of the same
capacity or higher than the machine in use,
according to the length of the cable.
5. CONNECTING THE OUT-PUTS
The welding cables are connected by means of
a quick coupling system that uses special con-
nectors (DINSE and Euroconnector). The
ground cable must first be connected to the con-
nector (DINSE) (18 in Fig.1 for models TM 230,
TM 260 and TM 300) (18a and 18b in Fig.1 for
models TM350, TM 320W and TM360W with
selectable inductance) (18a, 18b and 18c in
Fig.1 for model TM 420W, TM500W and
TM650W with selectable inductance).
The connector of the torch must be connected to
its own connector (Euroconnector) (14 in Fig. 1).
This connector also allows connecting the elec-
trical contacts of the torch and tube that carries
the welding gas to the torch.
Before starting to weld, refer to the following sec-
tions for more information on the connections.

1. Connect the pressure regulator (2) to the
cylinder (3). Make sure the regulator is suitable
for the cylinder pressure. Attach the connector
nut (6) of the regulator (2) to the cylinder (3).
(Do not screw too tightly; excessive force could
damage the valve (1) of the cylinder (3).)
2. Connect the gas tube (4) to the regulator (2)
and secure with a cable tie (5).
3. Make sure that the gas tube is connected to
the welder correctly.
4. Open the valve (1) of the cylinder (3). Press
the torch trigger and check the gas is flowing
correctly. To carry out this operation release the
clutch of the motor.
Warning: Cylinders contain high-pressure gas;
handle with extreme care. Inappropriate hand-
ling and use could cause serious accidents.
Never stack the cylinders or expose to excessi-
ve heat, flames or sparks. Do not bash the cylin-
ders together. Contact your supplier for further
information on the use and maintenance of the
cylinders.
Warning: Never use damaged cylinders: in this
case, advise your supplier immediately.
7. MIG TORCH
We would advise you to carry out regular con-
trols on the condition of the welding torch; in
particular, always check the nozzle/gas blowpi-
pe (Fig. 4A) the wire feeder tip (Fig. 4B), and the
internal sheath of the torch. These parts must
be kept well-cleaned and intact. If the wire stops
threading correctly. replace the wire guide.
N.B. Each wire and diameter corresponds to an
appropriate wire feeder tip and sheath. Always
make sure you are using the correct type.
8. PREPARING FOR WELDING
1. Connect the welding machine to the line with
the proper plug.
2. Check the correct polarity of the torch and
ground cable
3. Connect the ground terminal to the work-
piece, making sure that the contact is good
next to the welding points and that there is no
insulating paint.
