Remote Controls; Generator Maintenance - Cebora 366 Manual De Instrucciones

3.6.3.1 Updating
· After turning on the machine, select the parameters to
be edited and edit them.
· Hold down the AQ button for more than 3 seconds, until
the save is confirmed (program symbol changes from
flashing to steady).
3.6.3.2 Save in a new program
· After turning on the machine, select the parameters to
be edited and edit them.
· Weld, even briefly.
· Briefly press the selector switch AQ until the desired
program is displayed.
· Hold down the AQ button until the save is confirmed
(program symbol changes from flashing to steady).
3.6.4 Weld with synergy.
The purpose of "synergy" is to offer the operator a quick
guide for setting the TIG welding parameters. It is there-
fore not compulsory, but only a suggestion.
"Synergic" relationships between current thickness and
electrode diameter have been developed using Ceriati
grey 2% electrodes (EN26848 WC20), at an alternating
current frequency of 90 Hz.
The teasts were carried out with the waveform n°. 12
(square penetration - sinusoidal cleaning).
The logic: The operator sets the type of material to be
welded, the welding position and thickness in relation to
the welding process; an electrode diameter is suggested
based on these choices, and if confirmed the machine
prepares for welding.
Turning on synergy.
Briefly press the key H (for less than 0.7 sec):the LED I
(Syn) lights simultaneously with the LED L (material). The
display O shuts off and the display U displays a message
corresponding to the material to be welded (see descrip-
tion of LED L). Turn the knob Y to choose.
Pressing the button H again confirms the choice of material
and causes the LED M to light. The display U shows the
welding positions available (see description of LED M).
Turn the knob Y to choose. Pressing the button H again
confirms the choice of position and causes the LED S to
light. The display O shows the set current, while the dis-
play U shows the thickness in millimeters that corre-
sponds to the current (see description of LED S).
Pressing the button H again confirms the choice of thick-
ness and causes the LED R to light.
One or more electrode diameters are proposed based on
the set choice of material, position, thickness and current.
The recommended electrode will be proposed first and
the numerical value of the diameter will always be steadi-
ly lit, next to the letter A if the amp setting selected for
welding falls within the current range of two diameters;
the second choice of electrode diameter will be proposed
only if the encoder Y is turned. The second choice will
also be displayed steadily lit. If you turn the encoder fur-
ther, the display U shows the diameter above the second
choice and below the first choice, flashing.
Given that the electrode diameter mainly defines the start
level AO and the minimum current AI, the operator may
choose a combination that is not recommended.
At this point the operator has two choices:
22
1. To exit synergy without confirming the choices made.
To do so, briefly press the button H; the LED I shuts off
and the panel displays the settings in effect before you
entered synergy.
2. Confirm the synergy by pressing the button H for
longer than 0.7 sec. At this point all synergy functions are
set and, if selected using the button AP, the display U
shows the message "AU" (automatic).
The LED I remains lit to confirm that the parameters have
been set.
To summarize, when you confirm the electrode diameter
(by holding down the button H when the LED R is select-
ed) the start, wave, Hz, balance and current AI functions
are arranged according to the automatic logic described
previously. When the electrode is confirmed, the LED R
shuts off and the LED I lights.

4 REMOTE CONTROLS

The following remote controls may be connected to
adjust the welding current for this welding machine:
Art.1256 TIG torch button only (water-cooled).
Art.1258 TIG torch UP/DOWN (water-cooled).
Art. 193 Foot control (used in TIG welding)
Art 1192+Art 187 (used in MMA welding)
Art. 1180 Connection to simultaneously connect the torch
and the pedal control. Art 193 may be used in any TIG
welding mode with this accessory.
Commands that include a potentiometer regulate the
welding current from the minimum to the maximum
current set via the knob Y.
Commands with UP/DOWN logic regulate the welding
current from the minimum to the maximum.
The remote control settings are always active in the PL
program, while they are not active in a saved program.
5 MAINTENANCE
Any maintenance operation must be carried out by qua-
lified personnel in compliance with standard CEI 26-29
(IEC 60974-4).

5.1 GENERATOR MAINTENANCE

In the case of maintenance inside the machine, make
sure that the switch BE is in position "O" and that the
power cord is disconnected from the mains.
It is also necessary to periodically clean the interior of the
machine from the accumulated metal dust, using com-
pressed air.
5.2 PRECAUTIONS AFTER REPAIRS.
After making repairs, take care to organize the wiring so that
there is secure insulation between the primary and secon-
dary sides of the machine. Do not allow the wires to come
into contact with moving parts or those that heat up during
operation. Reassemble all clamps as they were on the origi-
nal machine, to prevent a connection from occurring
between the primary and secondary circuits should a wire
accidentally break or be disconnected.
Also mount the screws with geared washers as on the ori-
ginal machine.
