3~ 50/60HZ 50- or 60-Hz three-phase power supply
I1. Absorbed current at the corresponding cut
ting current I2.
IP21. Protection rating for the housing
Grade 1 as the second digit means that this
equipment is not suitable for use outdoors
in the rain.
S
Suitable for use in high-risk environments.
NOTES: The machine has also been designed for use in
environments with a pollution rating of 3. (See IEC 664).
3 INSTALLATION
3.1 TORCH ASSEMBLY
This system is supplied without a torch, and is suit-
able for use only with CEBORA torches CP90, CP160
and CP200, both manual and automatic (straight).
After inserting the mobile fitting F in the guard D,
insert it on the fixed fitting C, fully tightening the ring-nut
of the fitting F to avoid air leaks that could interfere with
smooth operation.
Be careful not to dent the contact pin, and not to bend
the pins of the mobile fitting F .
Screw the guard 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.
Connect the gas intake to the fitting I, making sure that
the system is capable of providing the throughput and
pressure required by the torch used.
If air is supplied by a compressed air cylinder, it must be
equipped with a pressure regulator; never connect a
compressed air cylinder directly to the machine regu-
lator. The pressure could exceed the regulator capac-
ity, causing it to explode.
Make sure that the supply voltage matches the one
shown on the label applied to the power supply cable.
Otherwise, use the voltage change terminal board AE
inside the machine (fig.3).
fig. 3
The machine is equipped with a function switch, thus:
A) If the machine is permanently connected to the power
mains (without a plug), you must install a main switch of
appropriate capacity in accordance with the rating plate.
B) If the machine is plugged in, use a plug with a capaci-
ty in accordance with the rating plate. In this case the
plug must be used to disconnect the machine entirely
from the mains, after first setting the switch A (fig. 2) to
"O".
The yellow-green wire of the power supply cord must be
connected to the earth terminal.
Any extension cords must be sized appropriately for the
absorbed current I1, indicated on the rating plate.
3.3 DESCRIPTION OF PROTECTIVE DEVICES
Thermal cut-out:
Prevents overloads; located on the windings of the power
transformer, and indicated by the LED AB (see fig.2).
Torch recognition:
Predisposes the power source to work with parameters
suited to the type of torch connected.
Pneumatic:
Prevents the machine from working when the gas pres-
sure is too low. Located on the torch power supply, and
indicated by the LED AA (see fig.2). If the led flashes for
60', this means that the pressure was low for a brief time.
Hydraulic (for torch CP200 only).
Prevents the machine from working when the pressure of
the coolant is too low.
Electrical:
1) located on the torch body, prevents hazardous volt-
ages from being present on the torch when replacing the
nozzle, diffuser, electrode or gas nozzle holder;
2) prevents the machine from running when the elec-
trode is so worn that it must be replaced.
The LED AD (fig.2) lights to indicate this function.
3) prevents the machine from running in hazardous
conditions. The LED AC lights to indicate this function.
To ensure the efficiency of these safety devices:
• Do not remove or short-circuit the safety devices.
• Use only original spare parts.
• Always replace any damaged parts of the machine
or torch with original materials.
• Use only CEBORA torches type CP90, CP160 and
CP200.
4 USE
Before using the equipment, read the standards CEI 26/9
- CENELEC HD 407 and CEI 26.11 - CENELEC HD 433
carefully, and make sure all cable insulation is intact.
4.1 CUTTING
Turn on the machine using the knob A. This step will be
confirmed when the pilot lamp B lights.
If the torch CP200 is connected, the LED V will flash for
15 seconds, during which time the machine will not work,
to ensure that coolant is circulating in the pipes.
Press the torch trigger very briefly to open the gas flow.
Make sure that, in these conditions, the pressure reading
