INSTALLATION.
The equipments must be installed by skilled personnel.
All connections must be made in full compliance with cur-
rent safety laws.
3.1
Installation.
The control panel does not operate independently but must
be connected to the power source, with which it communi-
cates and from which it receives its power supply.
Connect the control panel (24) to the power source (21)
using the connection cable (1).
If present, place the robot interface (25) inside the robot
control cabinet (5), following the instructions given in the
robot interface instructions manual.
Complete the remaining connections of the other welding
system equipments, consulting the corresponding instruc-
tion manuals (par. "Installation").
Power the welding system using the M switch of the pow-
er source (see power source Instructions Manual).

3.2
"Robot interface" function activation.
These equipments may operate independently from the
robot system or in integrated mode as part of the robotic
welding system.
In both cases the equipments must be completely wired
and connected together and to the robot system.
The integration between the Cebora welding system and
robot system is determined by the "Robot interface" func-
tion:
− "Robot interface" function not active = "independent"
operation;
− "Robot interface" function active
operation.
The "Robot interface" function becomes available in the
control panel menu, only if the CAN2 serial line is enabled
("Auxiliary CAN" function) (see Menu Map, par. 10).
The sequence to enable both functions is described in par.
8.2.2, "Auxiliary CAN" function and 8.2.3, "Robot inter-
face" function.
3.3
System Operating Modes.
With the "Robot interface" function active, the system of-
fers 7 Operating Modes, selectable from robot control and
in one case also from control panel:
Standard mode, for conventional synergic MIG welding
(MIG Short);
Pulsed arc mode, for pulsed synergic MIG welding (MIG
Pulsed);
Job mode, for welding with spots pre-set by the user;
24
Parameter selection internal mode, to enable the control
panel to operate the power source operating settings
without disabling the "Robot interface" function;
Manual mode, for manually controlled MIG welding (not
synergic);
HD (High Deposit) mode, for MIG synergic welding
(MIG Short), with synergic parameters particular ad-
justing;
Root mode, for MIG synergic welding (MIG Short), de-
signed for vertical "butt" welds.
The Operating Modes setup are described in the MIG
Digital Protocols Instructions Manual, cod. 3300362,
supplied with the power source.
The control panel commands and signalling, according to
the selected operating mode, are described in the par. 4 and
shown in Fig. 4.
The term "program" refers to a "MIG Short" or "MIG
pulsed" synergic curve developed by Cebora and saved
in the firmware, in non-editable form, in a memory area
called "program number".
The term "Job" refers to a working point developed start-
ing from a synergic curve, among those provided by Ceb-
ora, with some parameters changed by the user and then
saved in a memory area called "Job number".
3.3.1
Standard mode uses MIG welding programs with
short-circuit arc transfer (MIG Short) in which Cebora has
combined each wire speed with the welding voltage to ob-
tain a stable arc position.
This combination is called "synergy".
The wire speed and welding voltage may be changed using
=
"integrated"
the analogue signals:
− "Analog set point 0" (Welding Power);
− "Analog set point 1" (Arc Length Correction),
available from robot terminal.
This welding process is indicated on D3 in the main page
with "MIG –" indication and by the L10 lit.
3.3.2
Pulsed arc mode uses MIG welding programs with pulsed
arc transfer (MIG Pulsed) in which Cebora has combined
each wire speed with the welding voltage to obtain a stable
arc position.
This combination is called "synergy".
The wire speed and welding voltage may be changed using
the analogue signals
− "Analog set point 0" (Welding Power);
− "Analog set point 1" (Arc Length Correction),
available from robot terminal.
NOTE
Standard mode.
Pulsed arc mode (optional).
