Description Of The Equipment - Cebora SOUND AC-DC 1530/M Manual De Instrucciones

If the message E2 appears on the display, the machine
requires technical intervention.
3 INSTALLATION
Make sure that the supply voltage matches the voltage indi-
cated on the specifications plate of the welding machine.
When mounting a plug, make sure it has an adequate capa-
city, and that the yellow/green conductor of the power sup-
ply cable is connected to the earth pin.
3.1 START-UP
Only skilled personnel should install the machine. All con-
nections must be carried out according to current regula-
tions, and in full observance of safety laws (regulation CEI
26-10 - CENELEC HD 427).

3.2 DESCRIPTION OF THE EQUIPMENT

A - Procedure selector switch
This push-button selects the welding procedure
(MMA or TIG).
When selected, one of the following LEDs lights:
B , C , or D
Mode key E.
When selected, one of the following LEDs lights:
F, G, H, L, M, N.
In TIG mode there will always be two LEDs lit: one indicating
HF or striking start mode, and the other indicating conti-
nuous or pulse mode with 2- or 4-stage command. The
selection changes each time the button is pressed.
The LEDs light alongside the various symbols to display your
choice:
F - LED. TIG welding with arc started
without high frequency.
To light the arc, press the torch trigger and touch the tung-
sten electrode to the workpiece, then lift it. This move must
be quick and decisive (0.3 sec.).
L - LED. TIG welding with arc started with
high frequency.
To light the arc, press the torch trigger: a high voltage/fre-
quency pilot spark will light the arc.
G - LED. Continuous 2-stage TIG welding
(manual).
When the torch trigger is pressed, the current begins to
increase over the previously set "slope up" time, until it rea-
ches the value set by means of the knob AA. When the trig-
ger is released, the current begins to drop over the previou-
sly set "SLOPE DOWN" time, until it returns to zero.
In this position, you may connect the pedal control acces-
sory ART. 193.
H - LED. Continuous 4-stage TIG welding
(automatic).
This program differs from the previous one in that the arc is
both started and shut off by pressing and releasing the torch
trigger.
.
M - LED.
(manual).
When the torch trigger is pressed, the current begins to
increase over the previously set "slope up" time, until it rea-
ches the value set by means of the knob AA. When the trig-
ger is released, the current begins to drop over the previou-
sly set "SLOPE DOWN" time, until it returns to zero.
In this position, you may connect the pedal control acces-
sory ART. 193.
N - LED. Pulsed 4-stage TIG welding (auto-
matic).
This program differs from the previous one in that the arc is
both started and shut off by pressing and releasing the torch
trigger.
J - LED - THERMAL PROTECTION
Lights when the operator exceeds the duty cycle or percen-
tage intermittence admissible for the machine, and simulta-
neously blocks the current output.
NOTE: In this condition the fan continues cooling the
power source.
Y - LED
This LED must always be lit to ensure safe welding
conditions in AC mode.
AA - KNOB
Adjusts the welding current.
Also, in combination with the push-button P, you
may:
- adjust the second level of current V
-adjust the "slope up" S
-adjust the "slope down" W
- adjust the pulse frequency U
-adjust the post gas X
-adjust the current frequency in AC welding Q
-adjust the wave balance in AC welding R
-adjust the arc striking in relation to the diameter of the elec-
trode used in TIG AC mode (LED O).
Z - Display
Displays the welding current and the settings selected
by means of the push-button P and adjusted via the knob AA.
P - SELECTOR
When this button is pressed, the LEDs light in suc-
cession:
Q - LED
Current frequency in AC welding (50 - 150 Hz).
R - LED
Wave balance in AC welding (balance = 0; Cleaning
= from 1 to 8, flashing; Penetration = from 1 to 8,
not flashing).
O - Led
Displays the electrode diameter. The choice of electrode
diameter ranges from 1mm to 4mm. Use the knob AA to
change the diameter. This function is active only for AC TIG
welding.
