Protections.

5.4.1 Coolant pressure.
This protection is achieved by means of a pressure switch,
inserted in the fluid delivery circuit.
Low pressure is indicated by the abbreviation "H2O"
flashing on Control Panel.

CONTROL PANEL.

The Cebora TIG ROBOT Welding System equipments
may operate independently from the Robot System or in
integrated mode as part of the Automated Welding Plant.
The integration between the Cebora Welding System and
Robot System is determined by the Robot function, in the
"Second Functions" menu (par. 10.6):
− Robot function enabled (rob On) = "integrated"
operation;
− Robot function disabled (rob OFF) = "independent"
operation.
NOTE
This Instructions Manual refers to the Power Sources art.
369.80, 370.80, 371.80 in Robot applications and deals ex-
clusively with "integrated" operation, that is with Robot
function enabled (rob On) (led L37 lit).
6.1

System Operating Modes.

With the Robot function enabled (rob On), the Welding
System offers 3 Operating Modes:
− Job mode, for welding with spots pre-set by the user;
− Parameter Selection Internal mode, to enable the
Control Panel to operate the Power Source operating
settings without disabling the Robot function;
− TIG mode, for TIG welding, with parameter set by Ro-
bot Terminal.
For more detailed information refer to the "Digital Proto-
cols for Cebora TIG automated systems" cod. 3.300.363
supplied with the Power Source.
The Control Panel commands and signals are described in
par. 7.
6.1.1 Job mode.
The term "Job" refers to a working point realized from
the user by adjusting available parameters for TIG weld-
ing and then saved (stored) in a memory area called "Job
number".
The Job stored can be called up from the Robot Control by
selecting the "Job number".
For selection 8 digital signals are available: Job Number
(bit 7 ÷ 0).
If from Robot Control is selected the "Job number" = 0
(zero) then from the Control Panel, with key T5, is possi-
ble to call a stored Job (displayed on D1).
If from Robot Control is selected a "Job number" = 1 ÷
7 then on D1 will appear, for 5 s, the indication of the re-
called Job number (e.g.: P01).
If the indication is fixed, after 5 seconds the display indica-
tion disappears and on D2 remains the value of the parame-
ter denoted by one of the leds L22 ÷ L34.
If the indication is flashing, it means that the "Job number"
selected does not match any stored Job, the D1 indication
