Instructions For Plasma Cutter - Elettro CF PLASMA 55 Manual De Instrucciones

Before using this device all people authorized to its use,
repair or inspection, should read the book "Safety rules" and
the "Instruction manual" specific for every machine. Contact
your distributor if you have not understood some instructions.
1 SAFETY DEVICES
This unit is provided with the following safety devices:
Thermic: located on the power transformer windings to avoid
overloads. Signalled by indicator light C on (see pict. 1 - 1a).
Pneumatic: located on the torch feed line to avoid insufficient
air pressure. Signalled by indicator light E (see pict. 1 – 1a).
Electric: located on torch body to avoid dangerous voltages
while replacing nozzle, diffuser, electrode or nozzle holder.
- Do not remove or short-circuit the unit safety devices.
- Only use genuine spares.
- Always replace any damaged part of the unit or torch
with genuine material.
- Only use genuine torches.
- Do not let the unit work without covers. This would be
dangerous for operator and for those who are
surrounding the work area and would prevent the unit
from cooling efficiently.

3.1 ASSEMBLY AND ARRANGEMENT
Unpack the unit and assemble the handle with the supplied
spanner. Place the unit in properly ventilated if possible
undusty room making sure that the air inlet and outlet from
cooling slots are not obstructed.
The machine item 488 is suitable only for ELETTRO CF
torches type P50 and the machine item 489 only for
ELETTRO CF torches type P70. ELETTRO CF does not
assume any responsibility in case that a different kind of
torch is used.
3.2 SETTING AT WORK
The unit must be installed by skilled personnel. All
fittings must be in conformity with the existing rules and
in full compliance with safety regulations.
Connect the air feed to fitting on the air pressure reduction
unit I (pict. 2) making sure that pressure is 88PSI (6bar or
KPaX100) at least with a minimal capacity of 420 CFH (200
litres/min). Should air feed come from a pressure reducing
unit of a compressor or of a centralized plant, the reducing
