Safety Devices - Elettro PLASMA 35 INVERTER Betriebsanleitung

Before using this device, all people authorized 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 on the power transformer windings to avoid overloads and signalled by indicator light G on (see picture 1).
Pneumatic : located on the torch feed line to avoid insufficient air pressure and signalled by indicator light H (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 machine when there is high input voltage tension, this function is signalled by indicator light F (picture 1)
• Do not remove or short-circuit the unit safety devices.
• Only use original spares.
• Always replace any damaged part of the unit or torch with original material.
• Do not use any torches other than the original one.
• 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.
