INSTRUCTIONS FOR PLASMA CUTTER
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 DESCRIPTION OF PROTECTIVE DEVICES
Thermal cut-out
It prevents overloads. It is located on the windings
of the power transformer and it is indicated by the
LED
N (see pict. 1).
Torch recognition
It predisposes the power source to work with parameters
suited to the type of torch connected.
Pneumatic
It prevents the machine from working when the gas
pressure is too low. It is located on the torch power
supply and is indicated by the LED
L (see pict. 1). If
the led flashes for 60’', this means that the
pressure was low for a brief time.
Hydraulic (for torch P150W and P150W HF only).
It prevents the machine from working when the
pressure of the coolant is too low.
Electrical
1.
Located on the torch body, it prevents it from hazardous
voltages when replacing the nozzle, diffuser, electrode or
gas nozzle holder;
2. It prevents the machine from running when the
electrode is so worn that it must be replaced. The
LED
M (see pict.1) lights to indicate this function.
3. It prevents the machine from running in
hazardous conditions. The LED O (see pict. 1)
lights to indicate this function.
To ensure the efficiency of these safety devices:
•
Do not remove or short-circuit the safety devices.
• Use only original spare parts.
• Always replace any damaged parts of the machine or
torch with original materials.
• Use only ELETTRO CF torches type P70, P150, P150W
and P150W HF.
