Set up
The safety rules reported in the preceding sections
should be carefully followed when setting up the
machine.
Connect the power cable to a socket with an adequate
current supply and insert the delayed line fuses with
an adequate rated value, as specified in the table of
TECHNICAL DATA (page 45).
Make sure that the yellow-green wire, which is the
earth wire, is properly connected to the ground (this will
protect the user).
To start up the machine follow these steps:
•
Place the unit so that the vents are clear of any
obstruction to ventilation air. Keep it in a dry place
and at a distance of at least 0.5 m from walls, shields
or anything.
•
Make sure the machine is off.
•
Connect the compressed air hose to the regulating
filter connection 'A1' on the rear panel of the
machine. Should compressed air be supplied from a
bottle or pneumatic circuit delivering it at a pressure
above 10 bar, a pressure reducer should be there to
reduce it to 10 bar. If the pressure entering the
regulating filter is higher, this may explode!
•
Connect the work return lead to the 'C2' socket on
the power source and clamp it to a clean area of the
workpiece.
•
Screw out the torch outside nozzle, turn on the
machine and make sure the pressure of the torch
trigger does not operate the power source. This
confirms proper functioning of the torch safety. After
this check, the torch outside nozzle can be screwed
in again.
•
Make sure the compressed air used for cutting is free
from oil, moisture, dust or any other polluter.
Compressed air can be adequately cleaned if special
filters are installed on the compressor outlet in
addition to the one present in the compressor. Dry
and clean air ensures better cut quality.
Notice:
In order to prevent the torch or its parts from serious
damage, always use original spares.

Notes on the use of the torch
A plasma torch is held at right angle to the workpiece
when a vertical cut is desired or at any other angle for
sloping cuts and bevels.
Cutting speed should allow the cutting arc to cut the
material and protrude from the workpiece vertically or at
a max. angle of 5÷10° to the perpendicular.
When plasma is used to pierce a material, molten
material ejection may deposit on the torch, thus causing
abnormal wear, especially with thickness over 10 mm.
In these cases it is suggested to start piercing with the
torch slightly slanting so that the ejection of molten
metal is directed outwards and the torch is preserved
from
deposited on the ceramic cap or on the nozzle
should be removed immediately paying attention to
the high temperature of the workpiece and torch
parts.
Circular cuts may be carried out by means of rotating
head calipers sliding on rollers, with magnetic
centering.
The machine should not be switched off before the
post-cut gas has flown completely, since this is
necessary to cool the torch.
In order to extend consumable life, both nozzle and
electrode should be replaced when servicing a torch.
The nozzle should be replaced when the inner bore is
irregular or greater than the nominal bore (this causes
raking and poor quality cuts); the electrode should be
replaced before the tungsten core of the electrode tip is
totally worn out. The use of worn parts may damage the
torch body.
Particular care should be taken in fitting the new parts
into the torch so as not to irrevocably damage the torch
body.
Attention: Only use the torch authorised by INE
(see page 37 – technical data). If another sort of
torch is used, it could cause irregular operations
and not guarantee the cutting quality nor operator
safety.
