IMPORTANT
READ THIS MANUAL AND THE SAFETY RULES
MANUAL CAREFULLY BEFORE INSTALLING, USING,
OR SERVICING THE MACHINE, PAYING SPECIAL
ATTENTION TO SAFETY RULES. CONTACT YOUR
DISTRIBUTOR IF YOU DO NOT FULLY UNDERSTAND
THESE INSTRUCTIONS.
This machine must be used for cutting only.
It is also essential to pay special attention to the "SAFETY
RULES" Manual. The symbols next to certain paragraphs
indicate points requiring extra attention, practical advice or
simple information.
This MANUAL and the "SAFETY RULES" MANUAL must
be stored carefully in a place familiar to everyone involved
in using the machine. They must be consulted whenever
doubts arise and be kept for the entire lifespan of the
machine; they will also be used for ordering replacement
parts.
1. INSTALLATION
1.1. TORCH ASSEMBLY (see pict. 4)
Follow the torch installation sequence (Pict. 4), during
these operations the
disconnected from the mains.
Insert the torch male adapter in the corresponding
•
female connector on the front panel (1). Be careful to
align the black nylon pin, circled in white (2), with the
corresponding hole in the adapter.
Fully press the male adapter (3), then insert the
•
corresponding chrome-plated wrench in the female
adapter hole (4) and firmly press the inner unlocking
tab.
While holding the female adapter inner unlocking tab
•
pressed by means of the corresponding chrome-plated
wrench, turn the ring nut of the torch male adapter
clockwise (5) until it is fully seated (6). The torch is now
ready for use.
Do not dent the current pin or bend the pins of the torch
fitting. A dented pin may not be disconnected, while a bent
pin does not allow proper insertion onto the female adapter,
thereby preventing the machine from working.
This machine is suitable to work only with a genuine
ELETTRO C.F. torch. We do not assume any
responsibility in case that a different kind of torch is
used.

1.3. SAFETY DEVICES
This system comes equipped with the following safety
devices:
Overload cut-out:
To avoid overloads. It is evidenced by the LED C (see
pict.1) continuously on.
Pneumatic:
Located on the torch inlet to prevent low air pressure.
The LED D (see pict.1) lights when tripped.
It means that the pressure has temporarily gone below 3.2
÷ 3.5 bar.
Electrical:
Located on the torch body, to prevent hazardous voltages
from occurring on the torch when, swirl ring, electrode or
nozzle holder are replaced;
Do not remove or short-circuit the safety devices.

be
 Use only original spare parts.
 Always replace any damaged parts of the machine
with original materials.
 Do not run the machine without its housings. This
would be dangerous to the operator and anyone else
in the work area, and would prevent the machine from
being cooled properly.
