Connection of compressed air
Connect the compressed air hose to the rapid coupling (Fig. D).
Use a compressed air hose with a minimum internal diame-
ter of 8 mm.
Make sure that the gas feed pressure does not exceed 8,6
bar / 861 kPa. If the pressure is higher than this value, the fil-
ter could explode.
The plant must be fed with a constant air flow, with the follow-
ing characteristics:

Having pressed the compressed air button (Pos. 2, Fig. B),
set the pressure regulator to obtain the value indicated on the
table above, by raising and then rotating the ring nut, as indi-
cated in figure D. Once regulation has been completed, low-
er the ring nut.
The compressed air consumption in relation to the pressure,
the cutting mode, and the nozzle fitted, is shown in table 3.
NOTE: The pressure must be set with the pressure rising, while
the air / gas is flowing.
If the quality of the air / gas supply is not good, the cutting
speed diminishes, the cut quality worsens, the cuttable thick-
ness diminishes, and the working lifespan of consumables is
reduced.
If moisture, oil or other pollutants get into the air line, due to
the general compressor, use the additional CEA filtration sys-
tem, code 427529 (Fig. D) with a filtration grade of 0,01 μinch
- 0,25 μm available via CEA PLASMATECH distributors (the
order code for replacement filters is 427530).
The additional filtration system must be installed between the
air / gas supply and the filter located on the generator’s back
panel. Additional filtration could increase the minimum feed
pressure required.
