Earth Connection - Cebora SPOT 2500 Instruction Manual

D-LED. Signals activation of the pulse heating fun-
tion. for operation, read "manual – automatic func-
tion" LEd O.
E- LED. Signals activation of the rosette spot-weld-
ing function. for operation, read "manual – auto-
matic function" LEd O.
F- Key. Activates the rosette spot-welding function.
Performs traction on sheet metal after first mounting
the hammer on the gun and fastening the three-
pointed rosette to the hammer head.
The power is constant. Time is adjusted using the
buttons S and T. The display R shows the setting:
Minimum = 01 Maximum = 15.
G- LED. Signals activation of the insert spot-welding
function. for operation, read "manual – automatic
function" LEd O.
H- Key. Activates the insert spot-welding function.
fastens the various threaded inserts present in
modern auto bodies.
The power is constant. Time is adjusted using the
buttons S and T. The display R shows the setting:
Minimum = 01 Maximum = 50.
I- LED. Signals activation of the metal pressing
function. for operation, read "manual – automatic
function" LEd O.
L- Key. Activates the sheet metal pressing function.
serves to flatten sheet metal that has become mis-
shapen. It is carried out using the specific electrode.
Time is fixed, and the buttons S and T adjust the
power; the display R shows the setting: Minimum =
20 Maximum = 60.
M- LED. Signals activation of the sheet metal heat-
ing function. for operation, read "manual – auto-
matic function" LEd O.
N- Key. Activates the sheet metal heating function.
heats deformed sheet metal using carbon.
The time is unlimited. use the buttons S and T to
set a power; the display R shows the setting.
Minimum = 20 - Maximum = 60.
O- Automatic mode or manual selection key.
upon start-up, if the machine is set up for manual
mode "MAN" the LEd P lights.
NOTE: upon power source start-up the LEds flash,
indicating "stand-by" status: the machine is on, with
no voltage, awaiting commands.
select an operating function.
Selecting between manual and automatic mode
takes place by pressing the O key.
Manual mode means that, once the function is
selected, spot-welding is controlled by the trig-
ger; the LEd that indicates the function choice
remains lit without flashing, and the display R shows
the setting.
Warning: in this operating mode the power source
never enters "stand-by."
Automatic mode means that spot-welding is not
controlled by the torch trigger. In relation to this
the LEds that show activation of the function have
two operating modes:
8
1) Flashing the machine does not deliver voltage. This
means that it is waiting for the operator to select a
function, or that the machine has been inactive for
more than two minutes. The display R shows two
lines ("stand-by").
2) NOT flashing the machine delivers reduced voltage,
and to carry out the job set by the operator, it auto-
matically makes sure there is contact between the
torch and the workpiece. The display R shows the
setting numerically, and the keys T and S are
active.
NOTE: In automatic mode, once a function is enabled,
the machine generates a low voltage that serves to
check the contact between the gun and the work-
piece; thus to correctly perform the job, proceed as
follows:
Rest the spot-welding electrode firmly and steadily
on the workpiece.
Let the machine perform the job.
Lift up from the working position and do not rest
the gun in zones that might accidentally come
into contact with earth.
P- LED which signals manual mode.
Q- LED which signals automatic mode.
R- Display shows the settings made with the keys S
and T.
S- Key increases the values shown on the display R.
T- Key reduces the values shown on the display R.
U-V- Power sockets for earth cable and spot-weld-
ing gun.
W- 3-pin socket to which to connect the male patch
connector of the spot-welding gun, essential for
manual mode.
Warning: use only original torches; others might
damage the machine.
X- Switch that turns the machine on and off.
Y- Mains cable.

5 EARTH CONNECTION

The earth cable must be fastened as close as poss-
ble to the point where you will be working.
To fasten the quick earth supplied with the cable, pro-
ceed as follows:
for manual mode LEd P lit.
1) fasten the heating electrode to the welding gun
2) Press the button H; the LEd G lights.
3) use the key T to adjust the time to the minimum (05)
4) Rest the earth as close as possible to the working
area, after first removing all paint.
5) Rest the gun near the earth and press the trigger.
6) Raise the gun and turn the nut screwed onto the
earth probe clockwise.
for automatic mode, LEd Q is lit.
1) fasten any electrode to the welding gun
2) Press the button H; the LEd G stops flashing.
3) use the key T to adjust the time to the minimum (05)
4) Rest the earth probe as close as possible to the
working area, after first removing all paint.
