Instructions For Plasma Cutter - Elettro CF 492 Spare Parts

Important!
Before using this device all people authorised to its
use, repair or inspection, should read the book "Safety
rules for using machines" 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
windings to avoid overloads and signalled by indicator
light C on (see picture 1).
Pneumatic: located on the torch feed line to avoid
insufficient air pressure and signalled by indicator light
P (see picture 1).
Electric:
1) located on torch body to avoid dangerous voltages
while replacing nozzle, diffuser, electrode or nozzle
holder.
2) to stop the unit when the electrode is so worn that it
needs to be replaced. This second function is signalled
by indicator light P (picture 1).
3) located on the panel of the machine to avoid
dangerous tensions on the torch while replacing it.
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 spares.
−
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.
