- Insert the plug into the 230V socket.
- Switch on the system, ensuring the LED is working correctly.
If torch components are missing or have been assembled incor-
rectly, or the compressed air pressure is too low, or entirely
lacking, LEDs (14-15) turn on respectively to display the fault.
The generator is shut down until the fault is removed. Press the
gas test push button (16) in order to remove residual impurities
from the compressed air circuit, then lift and turn the knob to
adjust the pressure (7) until pressure-gauge (6) shows a pressure
reading of about 5 bars (carry out the operation keeping the gas
test button (16) pressed down, so as to make the adjustment
with air circulating in the piping).
- Set the value of the cutting current with the potentiometer
(17), keeping in mind the thickness to be dealt with.
- Press for a moment the torch button so as to generate the
pilot arc; release the control, checking that machine is cor-
rectly operating on the display panel. It is suggested to switch
off the pilot arc in order to prevent wear on the electrode
and the nozzle. If pilot arc is triggered without perfoming any
cutting action, the power source control unit will switch off it
after 6 seconds to prevent damage to the torch.
- Keep the torch at 90° on the piece.
- Press the torch button and strike the arc.
- Position the torch near the piece and begin cut-
ting, moving forward steadily.
(Consult the "S45" instruction manual).

3 SYSTEM PRESENTATION

3.1 General

Genesis 35 is a user-friendly, compact generator for plasma
cutting.
Genesis 35 uses compressed air as its only gas source, which can
be supplied from a normal compressor or from a suitably sized
centralized plant. It is able to carry out, cheaply, cuts of a high
quality up to a thickness of 15 mm in carbon steel, while still
keeping its weight and size very limited.
This optimum performance-to-weight ratio is made possible
thanks to the use, in common with all the Genesis range, of
inverter technology.
The current is thus stable, and unaffected by variations in the
supply voltage, in the height of the cutting arc, in the progres-
sion speed and in the thickness of the metal to be cut. The
Genesis 35 is equipped with an automatic circuit for the reigni-
tion of the pilot arc, that allows metal grill structures to be cut
in the best way.
There are safety systems that cut off the power circuit when the
operator comes into contact with live parts of the machine, as
well as controls to reduce the wear on the electrode and nozzle
at the moment of striking the cutting arc.
The ignition of the pilot arc takes place without the use of high
frequency, with an increase in the working life of the parts of the
torch subject to wear, and reduction in the mains interference.
