or incandescent metal, and a helmet or a welding cap.
- Wear masks with side face guards and suitable protection filter (at
least NR10 or above) for the eyes.
- Use headphones if dangerous noise levels are reached during the
welding (cutting).
Always wear safety goggles with side guards, especially during the
manual or mechanical removal of welding (cutting) slags.
lf you feel an electric shock, interrupt the welding (cutting) operations
immediately.
Other persons' protection:
- Position a fire-retardant partition to protect the surrounding area from
rays, sparks and incandescent slags.
- Advise any person in the vicinity not to stare at the arc or at the incan-
descent metal and to get an adequate protection.
- lf the noise level exceeds the limits prescribed by the law, delimit the
work area and make sure that anyone getting near it is protected with
headphones or earphones.
1.2 Fire/explosion prevention
The welding (cutting) process may cause fires and/or explosions.
- Compressed gas cylinders are dangerous; consult the supplier befo-
re handling them.
Protect them from:
- direct exposure to sun rays;
- flames;
- sudden changes in temperature;
- very low temperatures.
Compressed gas cylinders must be fixed to the walls or to other sup-
ports, in order to prevent them from falling.
- Clear the work area and the surrounding area from any infiammable
or combustible materials or objects.
- Position a fire-fighting device or material near the work area.
- Do not perform welding or cutting operations on closed containers or
pipes.
- lf said containers or pipes have been opened, emptied and carefully
cleaned, the welding (cutting) operation must in any case be perfor-
med with great care.
- Do not weld (cut) in places where explosive powders, gases or
vapours are present.
- Do not perform welding (cutting) operations on or near containers
under pressure.
- Don’t use this machine to defrost pipes.
1.3 Protection against fumes and gases
Fumes, gases and powders produced during the welding (cutting) pro-
cess can be noxious for your health.
-Do not use oxygen for the ventition.
- Provide for proper ventilation, either natural or forced, in the work
area.
- In case of welding (cutting) in extremely small places the work of the
operator carrying out the weld should be supervised by a colleague
standing outside.
- Position gas cylinders outdoors or in places with good ventilation.
- Do not perform welding (cutting) operations near degreasing or pain-
ting stations.
1.4 Positioning the power source
Keep to the following rules:
- Easy access to the equipment controls and connections must be pro-
vided.
- Do not position the equipment in reduced spaces.
- Do not place the generator on surfaces with inclination exceeding 10°
with respect to the horizontal plane.
1.5 lnstalling the apparatus
- Comply with the local safety regulations for the installation and carry
out the maintenance service of the machine according to the con-
structor's directions.
- Any maintenance operation must be performed by qualified person-
nel only.
- The connection (series or parallel) of the generators is prohibited.
- Before operating inside the generator, disconnect the power supply.
- Carry out the routine maintenance on the equipment.
- Make sure that the supply mains and the earthing are sufficient and
adequate.
- The earth cable must be connected as near the area to be welded
(cut) as possible.
- Take the precautions relevant to the protection degree of the power
source.
- Before welding (cutting) , check the condition of the electric cables
and of the torch, and if they are damaged repair or change them.
- Neither get on the material to be welded (cut), nor lean against it.
-The operator must not touch two torches or two electrode holders
at the same time.
1.6 Precautions against risks connected with the
use of compressed air
Connect the air supply to the coupling provided, making sure pressure
is at least 6 bars (0.6 MPa) with a minimum flow rate of 200 l/min. If the
air supply comes from pressure reducer of a compressor or a central
system, the reducer must be set to the maximum outlet pressure that
must not, however, exceed 8 bars (0.8 MPa). If the air supply comes
from a compressed air canister it must be equipped with a pressure
regulator.
A compressed air canister must never be directly
coupled to the machine pressure reducer. Pressure
might exceed the capacity of the reducer which might
consequently explode.

WARNING

2.0 ELECTROMAGNETIC COMPATIBILITY (EMC)
This device is built in compliance with the indications contained in the
harmonized standard EN50199, to which the operator must refer for the
use of this apparatus.
- lnstall and use the apparatus keeping to the instructions given in
this manual.
- This device must be used for professional applications only, in
industrial environments It is important to remember that it may
be difficult to ensure the electromagnetic compatibility in other
environments.
2.1 Installation, use and area examination
- The user must be an expert in the sector and as such is responsible
for installation and use of the equipment according to the manufac-
turer's instructions.
lf any electromagnetic disturbance is noticed, the user must soave the
problem, if necessary with the manufacturer's technical assistance.
- In any case electromagnetic disturbances must be reduced until they
are not a nuisance any longer.
- Before installing this apparatus, the user must evaluate the potential
electromagnetic problems that may arise in the surrounding area, con-
sidering in particular the health conditions of the persons in the vicinity,
for example of persons fitted with pacemakers or hearing aids.
2.2 Emission reduction methods
MAINS POWER SUPPLY
- The welding power source must be connected to the supply mains
according to the manufacturer's instructions.
In case of interference, it may be necessary to take further precautions
like the filtering of the mains power supply.
lt is also necessary to consider the possibility to shield the power supply
cable.
WELDING POWER SOURCE MAINTENANCE
The welding power source needs routine maintenance according to the
manufacturer's instructions.
When the equipment is working, all the access and operating doors and
covers must be closed and fixed.
The welding power source must not be modified in any way.
WELDING AND CUTTING CABLES
The welding (cutting) cables must be kept as short as possible, positio-
ned near one another and laid at or approximately at ground level.
EQUIPOTENTIAL CONNECTION
The earth connection of all the metal componente in the welding (cut-
ting) installation and near it must be taken in consideration.
However, the metal componente connected to the work-piece will
increase the risk of electric shock for the operator, if he touches said
metal componente and the electrode at the same time.
Therefore, the operator must be insulated from all the earthed metal
componente.
The equipotential connection must be made according to the national
regulations.
EARTHING THE WORKPIECE
When the workpiece is not earthed for electrical safety reasons or due
to its size and position, the earthing of the workpiece may reduce the
emissione. It is important to remember that the earthing of the work-
piece should neither increase the risk of accidents for the operators, nor
damage other electric equipment.
The earthing must be made according to the national regulations.
SHIELDING
The selective shielding of other cables and equipment present in the
surrounding area may reduce the problems due to interference. The
shielding of the entire welding (cutting) installation can be taken in con-
sideration for special applications.

4.0 MACHINE DESCRIPTION
Sistor 82 is a generator for plasma cutting, which is ideal for
medium and heavy structural work.
Sistor 82 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 25/30 mm in carbon steel, stainless
steel and aluminium. Nitrogen can also be used as gas with
reduced thickness and greater cutting precision.
The current is stable, precise and unaffected by variations in the
supply voltage, the height of the cutting arc, the progression
speed and the thickness of the metal to be cut.
This high performance is made possible thanks to the use of
state-of-the-art technology, which employs the high commuta-
tion speed possible with the latest electronic components.
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 nozz-
le at the moment of striking the cutting arc. The ignition of the
cutting arc takes place with the use of a high frequence voltage
discharge, that becomes automatically cut off when the opera-
tion is complete, thus limiting the emission of radio interferen-
ce in the rest of the cutting process.
The generator is equipped with:
- one torch fitting,
- an earth socket,
- front panel,
- rear panel.
4.1 Front control panel (Fig.1)

*I1: Off/On switch
Turns on the electric power to the welder.
It has two positions, "O" off, and "I" on.
*With the I1 switch in the "I" on position, the welder is
operational.
*The welder is connected to the mains supply even if the I1
switch is in the "O" position, and therefore there are elec-
trically live parts inside it. Carefully follow the instruc-
tions given in this manual.
*L1 : Voltage warning light green led.

lndicates that the safety devices like thermal cutout.
With "L2" on, the power source remains connected to the
supply mains, but does not supply output power.
"L2" remains on until the fault has been removed and in any
case until the inner temperatures are not within the normal
values; in this case it is necessary to leave the power source
on to exploit the operating ventilator and reduce the time
when it is not active.
* L3: compressed air alarm green led.
Means that the pressure of compressed air is below 3 bar, too
low for proper functioning. The generator has no power output.
* L4: Power output light red led.
Comes on when the arc is sparked, both during cutting and
when not cutting, and goes out as soon as the arc finishes.
* L5: torch cap alarm green led.
Means that the torch cap has not been properly tightened.
The generator has no power output.
In the event of an alarm, the operating condi-
tions are restored only if the cause is removed.
* R1: Potentiometer for setting the cutting current.
Allows you to continuously adjust the cutting current. This
current stays unchanged during cutting when the supply and
cutting conditions vary within the allowed ranges.
* T1: gas test pushbutton.
Allows impurities to be removed from the compressed air cir-
cuit and preliminary capacity and pressure settings to be
made with no power output.

8.0 CONNECTING THE EQUIPMENT COM-
PONENTS
Keep to the safety regulations contalned in section
“1.0 SAFETY”.
Connect the componente carefully, in order to
avoid power losses.
9.0 SETTING UP
For installation of the system, follow the instructions below:
1. Place the generator in a dry, clean place with suitable venti-
lation.
2. Connect up the compressed air supply with a 1/4 inch to the
air inlet P1 in the filter unit F1 (Fig.2). The pressure must
ensure at least 5 bars with a flow rate of at least 200 litres a
minute.
Securely connect the earth cable connector to the generator
as shown in figure 6.
3. Position the earthing clamp onto the piece to be cut, ensuring
that it makes a good electric connection (Fig. 6).
4. Check that all the components of the torch are present and
correctly fitted and connect the torch fitting to the connector
on the generator as shown in figure 5.
Insert the male fitting (torch side) into the corresponding
female fitting (machine side). Align the locating tooth (A) on
the housing and insert the ring nut (B) which must be com-
patible.
To permit screw-tightening of the ring nut (B), the tool provi-
ded (D) must be first inserted and pressed into the hole (C)
in order to release the anti-rotation lock. This operation must
be performed until the ring nut has been completely tighte-
ned. To disconnect the torch, first release the anti-rotation
lock by inserting the tool provided (D) into the hole (C).
Fig. 5
5. Switch on the system, ensuring the LED's are working cor-
rectly and some display.
If operating faults occur in the generator it will be inhibited
until normal operating conditions are restored. Press the gas
test pushbutton (T2 in Fig 1) in order to remove residual
impurities from the compressed air circuit, then lift and turn
the knob to adjust the pressure (F1 Fig.2) until the display D2
shows a pressure reading of 5 bars (carry out the operation
keeping the gas test button pressed down, so as to make the
adjustment with air circulating in the piping).
6. Set the value of the cutting current with the potentiometer,
keeping in mind the thickness to be dealt with.
7. Press for a moment the torch button so as to generate the
pilot arc; release the control, checking the machine is cor-
rectly operating with the display panel. It is advisable not to
keep the arc lit to no purpose without making contact, so as
to prevent wear on the electrode and the nozzle. If you con-
tinue to use it like this the apparatus itself will turn off the
pilot light after about 6 seconds.
In the case where a fault is found during the above phases,
check the LED's, the display and if necessary consult the
chapter "Possible electrical faults" in the manual.

12.0 THEORETICAL OUTLINE OF PLASMA
CUTTING
A gas assumes the plasma state when it is brought to an extre-
mely high temperature and ionizes wholly or partly, thus beco-
ming electrically conductive.
Although the plasma exists in every electric arc, by the term
"plasma arc" we refer specifically to a torch for welding or cut-
ting that uses an electric arc, made to pass through the constric-
ting neck of a suitable nozzle, to heat a gas coming out of this,
so as to take it to the plasma state.

12.1 Plasma cutting process
The cutting action is obtained when the plasma arc, made very
hot and highly concentrated by the design of the torch, transfers
onto the conductive piece to be cut, closing the electrical circuit
with the generator. The material is first melted at a high tempe-
rature of the arc, and then removed by the high exit velocity of
the ionized gas from the nozzle.
The arc can have two different states: that of the transferred arc,
when the current passes through the piece to be cut, that of the
pilot arc or non-transferred arc, when this is sustained between
the electrode and the nozzle.
13.0 CUTTING SPECIFICATIONS
In plasma cutting, the thickness of the material to be cut, the
speed of cutting and the current supplied by the generator have
values which are related to each other; these depend on the type
and quality of the material, type of torch as well as the type and
condition of the electrode and nozzle, distance between nozzle
and piece, pressure and impurity of the compressed air, cut qua-
lity required, temperature of the piece to be cut, etc.
In the diagrams as in Fig.8, 9 we can see that the thickness to be
cut is inversely proportional to the cutting speed, and that both
these values can be increased with an increase in current.
The cutting tests have been performed in standard operating
conditions using a Trafimet torch at 90A.
