1 DESCRIPTION OF PROTECTIVE DEVICES
Thermal cut-out
It prevents overloads. It is located on the windings of
the power trans former and it is indicated by the LED
B (see pict. 1).
Torch recognition
It predisposes the power source to
s uited to the type of torch connected.
Pneum atic
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 A (see pict. 1). If
the led flashes for 60'', this means that the pressure
was low for a brief time.
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. T

conditions. Th e LED
this function.
4. It indicates that contact cutting is forbidden. This
occurs when the cutting voltage is set to greater than
50 A. The LED I (see pict.1) lights to indicate this
fu nction.
To ensure the efficiency of these safety devices:
• Do not remove or short-circuit
• Use only original spare parts.
• Always replace any damaged
torch with original materials.
• Use only ELETTRO CF torches type P70 and P150.

3.1 ASSEMBLY AND ARRANGEMENT
Unpack the unit and assemble the handle with the supplied
spanner. Place the unit in proper
dusty room making sure that the air inlet and
cooling slots are not obstructed.
Fit torch on the unit (Pict. 1 et pict. 3) as follows:
1) Unscrew the screws M6X16 on the front panel. Slip the
flange L on the torch Z and screw the torch in the fitting
K. Insert the flange positioning the insert with the spring
in the correspondin
Block the flange with the screws M6X16 in the holes with
the thread inserts.
2) For the replacement of the torch, unscrew the screw
M6X16, take away the flange L and unscrew the torch Z
from the fitting K. For the assemblage of the new torch
follow the instructions at the point 1. Pay particular
attention not to dent the power pin and not to bend the
adapter pins; a dented pin cannot be disconnected, once
fit, from the fixed fitting K; a
fitting Z from being correctly mounted
