9. POWER CONNECTOR

Before connecting the machine check the tension,
number of phases and the power supply frequency.
The admissible power supply is indicated 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 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. A 2.5 mm² three-pole cable + earth, of the
same size or larger.

10. REMOTE CONNECTION

Figure 7 shows the connections of the remote
connector (13 of fig 1).

10.1 REMOTE CONTROL
WELDING CURRENT
With remote connector 13 in Fig. 1, it is possible to
adjust the current near to the point where the
welding is being carried out. To do so, it is
necessary to create
potentiometer P, shown in figure 7. The value of the
potentiometer is not a critical factor: between
2.2kOhm and 10kOhm 1/2W can be used.
Turn the potentiometer and select the welding
current in a range between minimum current from
display and the set value and the set value.

11. CONNECTING THE OUT-PUTS

Connection of the welding cables occurs via a
Dinse quick-connect system with appropriate
connectors.

1. Connect the pressure regulator (2) to the cylin-
der (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.
Warning: Cylinders contain high-pressure gas;
handle with extreme care. Inappropriate handling
and use could cause serious accidents. Never
stack the cylinders or expose to excessive heat,
flames or sparks. Do not bash the cylinders
together. Contact your supplier for further informa-
tion on the use and maintenance of the cylinders.
Warning: Never use damaged cylinders: in this
case, advise your supplier immediately
13. ORDINARY MACHINE
MAINTENANCE
Every three months periodically remove dust from
the suction nozzle using compressed air. Always
direct the air from the inside towards the outside
of the machine to avoid blowing dirt inside the
welder. When carrying out this operation, always
make sure the machine is not connected to the
power supply.
