Instructions For Plasma Cutter; Installation - Elettro CF Plasma Series Instructions Manual

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 pica 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. DESCRIPTION OF DEVICES ON THE MACHINE

1.2. SAFETY DEVICES
This system comes equipped with the following safety
devices:
Overload cut-out:
To avoid overloads. It is evidenced by the C led
continuously on (see pict.1).
Pneumatic:
Located on the torch inlet to prevent low air
pressure. The LED D lights when tripped (see
pict.1).
The blinking D led means that the pressure has temporarily
gone below 3.2 ÷ 3.5 bar.
Electrical:
1. It signals the presence of dangerous tensions
inside the machine. The LED B (see pict.1) lights
to indicate this function. The LED B keeps on
lighting, even after having switched off the machine, until
dangerous internal tensions persist.
2. Located on the torch body, to prevent hazardous
voltages from occurring on the torch when, swirl ring,
electrode or nozzle holder are replaced.
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
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.
