INSTRUCTIONS FOR PLASMA CUTTER
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.

1.2 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).

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 havin

2. Located on the torch body, to prevent hazardous
voltages from occurring on the torch
electrode or nozzle holder are replaced.
To nsure the efficiency of these safety devices:
y Do not remove or short-circuit the safet
y Use only original spare parts.
Always replace any da
with original materials.
Do not run the machine without its housings. This
would be dangerous to the operator and anyone else
