Instructions For Plasma Cutter; Explanation Of Technical Specifications; Safety Devices - 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. TORCH ASSEMBLY
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.
1.2. DESCRIPTION OF DEVICES ON THE MACHINE
(Pict. 1)
A) Mains power led.
B) Block LED; lights when hazardous conditions arise
(See 5.1.1).
C) Thermostat LED.
D) Low air pressure LED.
E) Torch.
F) Cutting current regulator knob.
G) Grounding clamp.
H) Pressure gauge.
I) Mains power switch.
J) Power cord.
K) Pressure regulator knob.
L) Compressed air fitting (1/4" female gas thread).
M) Water trap.

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.

INSTRUCTIONS FOR PLASMA CUTTER


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.

1.4. EXPLANATION OF TECHNICAL SPECIFICATIONS

IEC 60974-1 .... The equipment is built according to these
IEC 60974-10 standards.
IEC 60974-7
Cl. A ................. Machine for professional and industrial use.
Three-phase
frequency converter.
................. Down slope.
............ Suitable for plasma cutting.
TORCH TYPE . Type of torch that may be used with this
machine to form a safe system.
U0 .................... Secondary open-circuit voltage.
X ...................... Duty cycle percentage.
The duty cycle expresses the percentage of
10 minutes during which the welding
machine may run at a certain current I
voltage U
I ...................... Cutting current.

welding current I
on the distance between the contact tip and
the workpiece.
If this distance increases, the cutting
voltage also increases and the duty cycle
X% may decrease.
U .................... Rated supply voltage.

current absorbed, considering the duty
cycle. This value usually corresponds to the
capacity of the fuse (delayed type) to be
used as a protection for the equipment.
