2.4 Installation

Connection for MMA welding
The connection shown in the figure produces
reverse polarity welding. To obtain straight polar-
ity welding, reserve the connection.
- Connect (1) the earth clamp to the negative socket (-) (2) of
the power source.
- Connect (3) the electrode holder to thpositive socket (+) (4)
of the power source.
Connection for TIG welding
- Connect (5) the earth clamp to the positive socket (+) (6)
ofthe power source.
- Connect the TIG torch coupling (7) to the torch socket (8)
ofthe power source.
- Connect the gas hose from the cylinder to the rear gas con-
nection.
- Connect the signal cable of the torch to the appropriate con-
nector (9).
- Connect the gas hose of the torch to the appropriate union/
connection (10).
- Connect the red colored
inlet quick connector of the cooling unit.
- Connect the blue colored
outlet quick connector of the cooling unit.

3 SYSTEM PRESENTATION

3.1 General

The URANOS 4000 AC/DC are constant current inverter power
sources developed for electrode (MMA), TIG DC (direct current)
and TIG AC (alternating current) welding.
They are fully digital multiprocessor systems (data processing on
DSP and communication over CAN-BUS), capable of meeting
the various requirements of the welding world in the best pos-
sible way.

3.2 Front control panel

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 (consult the "Alarm
codes" section).
3 Power on
Indicates the presence of voltage on the equipment
outlet connections.
4 7-segment display
Allows the general welding machine parameters to be
displayed during start-up, settings, current and voltage
readings, while welding, and encoding of the alarms.
5 LCD display
Allows the general welding machine parameters to be
displayed during start-up, settings, current and voltage
readings, while welding, and encoding of the alarms.
Allows all the operations to be displayed instantaneously.
