is suitable for torches CEBORA CP161 both manual
and automatic (straight) and CP101.
After introducing the mobile fitting
F
into the protection
D
, insert it onto the fixed fitting
C
, by screwing down the
fitting collar
F
to avoid air leaking that may jeopardize a
good operation.
Do not dent the contact tip, do not bend the mobile fit
-
ting
F
pins.
Screw the protection
D
onto the panel.
3.2 START-UP
Only skilled personnel should install the machine.
All connections must be carried out according to
current regulations, and in full observance of safety
laws (CEI 26-23 and IEC/TS 62081 standards)
.
Connect the gas supply to fitting I making sure that the
equipment can supply adequate capacity and pressure to
the torch being used.
If the air is supplied from a compressed air cylinder, the
cylinder must be equipped with a pressure regulator;
nev-
er connect a compressed air cylinder to the machine
reducer direct. Pressure may be higher than the re
-
ducer capacity with consequent possible explosion
.
Make sure that the supply voltage matches the voltage in-
dicated on the specifications plate of the power cable. If
not, change voltage by means of the terminal board inside
the equipment (fig.3).
Fig. 3
The machine is equipped with a function switch, and
therefore :
a) In case of a permanent connection to the power system
(with no plug) a main switch of adequate capacity must
be provided for according to the plate specifications.
b) In case of a plug connection use a plug complying
with the plate specifications. In this case the plug must
be used to completely disconnect the machine from the
mains, after setting the switch
A
to “O” (fig. 2).
The yellow-green wire must be connected to the earth
terminal.
Extension cords must have a section complying with the
maximum absorbed voltage I1 indicated on the specifi
-
cations plate.
4. USE
Select type of work by means of button
W
: LED’s
N, O,
P
corresponding to CUT, grid cutting (SELF -RESTART)
and GOUGE will glow.
Turn the equipment on by means of knob
A
(displays
U,
V, R
and LED’s
N, O, P, T
and
S
will glow).
The following data will be rapidly displayed :
-power source code (display
U
),
-installed firmware version (display
V
),
-name of assembled welding torch (display
U
and
V
).
Then display
U
will show wording LEN (welding torch
length) and on display
V
size (= 12 meters from supplier)
will be flashing.
If the welding torch length is different, the size must be
changed by means of knob
Z
.
After 5 seconds the selected value is stored and main-
tained every time the power source is started. If the initial
setting is not correct, it is possible to change the length
by pressing simultaneously buttons
W
and
Q
and select-
ing the required size with knob
Z
.
Now it is possible to set the correct working pressure
by pressing button
Q
(SET) and following instructions of
S
and
T
LED’s. LED
S
on indicates a low pressure while
LED
T
on indicates a high pressure. Keep down knob
H
of
the pressure reducing valve until both LED’s are on (cor-
rect pressure). Push down to lock this knob.
4.1 CUTTING (“CUT” OPERATING MODE)
With knob
Z
adjust the cutting current according to the
thickness to be cut by following the cutting table instruc-
tions.
While the current is adjusted display
V
will show the cor-
rect diameter of the nozzle to be used.
Connect the earth cable clamp to the workpiece to be
cut making sure that the clamp and the workpiece have a
good electric contact especially in case of painted or oxi-
dized plates or with insulating coatings. Do not connect
the clamp to the material to be removed.
Select the cutting current by means of the knob
Z
.
Cebora CP101 welding torch
:
with nozzle ø 1.2 and 45 to 60 A currents use the two
faces spacer Art. 1404.
Cebora CP161 welding torch
:
With a 20 to 40A cutting current and a 0.8 mm
diameter nozzle a cut can be made by placing the
nozzle directly on the workpiece (drag cut).
For currents higher than 40A a spring spacer or a 2-end
spacer must be used to avoid to put into direct contact
the nozzle or the nozzle protection with the workpiece
to be cut.
With the welding torch in automatic mode, keep a dis-
tance of approximately 4mm between the nozzle pro-
tection and the workpiece, as indicated in the cutting
tables.
Press the torch trigger to start the pilot arc.
