2.0 INTRODUCTION
Genesis 30 is a user-friendly, compact generator for plasma cutting.
Genesis 30 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 10 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 progression speed and
in the thickness of the metal to be cut. The Genesis 30 is equipped
with an automatic circuit for the reignition 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.
The generator is equipped with:
- a torch, an earth (+) socket,
- front panel,
- rear control panel.
2.1 CONTROLS
2.1.1 Front control panel FP120 (Fig.1)
* L1 : Voltage warning light green led.
Comes on with the start switch (Fig.2) "I1" in position "I" and indicates that the plant is on and there is voltage.
* Power output light red led.
Comes on as soon as the cutting process starts, and goes off as soon as
it is finished.
* L3: torch cap alarm red led.
Means that the torch cap has not been properly tightened. The generator has no power output.
* L4: compressed air alarm red led.
Means that the pressure of compressed air is below 3.5 bar, too low
for proper functioning.
The generator has no power output.
* L5: Thermal safety device warning light yellow led.
lndicates that the safety devices like thermal cutout.
With "L5" on, the power source remains connected to the supply
mains, but does not supply output power. "L5" 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
16
leave the power source on to exploit the operating ventilator and reduce the time when it is not active.
* P1: 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 circuit and
preliminary capacity and pressure settings to be made with no power
output.

Fig. 3
6.0 PROBLEMS - CAUSES
6.1 POSSIBLE CUTTING DEFECTS
*: Fuses with a 20A rating are required to make maximum use of the potential of the power
source.
The electrical system must be made by skilled technicians
with the specific professional and technical qualifications
and in compliance with the regulations in force in the
country where the equipment is installed.
The welding power source supply cable is provided with a
yellow/green wire that must ALWAYS be earthed. This yellow/green wire must NEVER be used with other voltage
conductors.
* Verity the existence of the earthing in the used plant and the good
condition of the socket/s
* lnstall only plugs that are homologated according to the safety re-
gulations.
5.3 CONNECTING THE EQUIPMENT COMPONENTS
Keep to the safety regulations contalned in section 1.0
WARNINGS-PRECAUTIONS-GENERAL ADVICE.
Connect the componente carefully, in order to avoid power losses.
5.4 SETTING UP
To set up the plant, follow these instructions:
1. Place the generator in a dry, clean place with suitable ventilation.
2. Connect up the compressed air supply with a 1/4 inch to the air inlet
P1 in the filter unit F (Fig.2). The pressure must ensure at least 5 bars
with a flow rate of at least 100 litres a minute.
3. Position the earthing clamp onto the piece to be cut, ensuring that it
makes a good electric connection (Fig. 3).
4. Check that all the components of the torch are present and correctly
fitted.
5. Switch on the system, ensuring the LED's are working correctly.
If torch components are missing or have been assembled incorrectly,
or the compressed air pressure is too low, or entirely lacking, leds L3
and L4 in figure 1 come on respectively to display the fault. The generator is shut down until the fault is put right. Press the gas test
pushbutton (T1 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 manometer M1 shows a pressure reading
of about 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 correctly 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 continue 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
display LED's, and if necessary consult the chapter "Possible electrical
faults" in the manual.

8.1.1 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 temperature 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.
8.1.2 Caracteristics of a generator for plasma cutting
A generator for plasma cutting carries out the following operations:
- ignites the pilot arc (for this you can use either a discharge of high frequency between electrode and nozzle, or special torches with retractable electrode);
- supplies the current and voltage to the pilot arc necessary to sustain it;
- checks the transition from the pilot arc to the cutting arc;
- supplies the current required for cutting to the cutting arc;
- oversees all the operations and suitably controls the air valve and
alarms.
The piece to be cut is connected to the positive pole of the cutting circuit,
as is the nozzle, while the electrode is connected to the negative pole.
The above-mentioned process allows cutting of all conductive materials, and thus also the non-ferrous metals for which cutting by an oxyacetylene process is impossible.
9.0 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 quality required, temperature of
the piece to be cut, etc.
In the diagrams as in Fig.7 and Fig.8, 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.
7.0 ROUTINE MAINTENANCE
Prevent metal powder from accumulating near the aeration fins and
over them.
Disconnect the power supply before every operation!
Carry out the following periodic controls on the power source:
* Clean the power source inside by means of low-pressure compressed
air and soft bristel brushes.
* Check the electric connections and all the connection cables.
For the maintenance or replacement of plasma torch
components, and/or earth cables:
* Disconnect the power supply before every operation.
* Check the temperature of the componente and make sure that
they are not overheated.
* Always use gloves in compliance with the safety standards.
* Use suitable spanners and tools.
* For torch maintenance, keep carefully to the directions shown
under instructions for use of the torch enclosed with this manual.
Tighten the componente with care, in order to avoid:
- heating;
- false contacts;
- gas leaks;
- mechanical damage.
Make sure that there is no dirt or metallic powder in the cooling pipes
and in the contact joints.
8.0 THEORETICAL OUTLINE OF PLASMA CUTTING
A gas assumes the plasma state when it is brought to an extremely high
temperature and ionizes wholly or partly, thus becoming electrically
conductive.
Although the plasma exists in every electric arc, by the term "plasma arc"
we refer specifically to a torch for welding or cutting that uses an electric arc, made to pass through the constricting neck of a suitable nozzle, to heat a gas coming out of this, so as to take it to the plasma state.
Fig. 4 Manual plasma cutting plant
8.1 Plasma cutting torch
Initially, for plasma cutting, a torch was used with a front end structure as
in Fig.5 and two types of gas: a first one for the formation of the plasma
(A) that passes between the electrode (1) and nozzle (2) and is forced to
exit in an ionized form through the hole, and a second one (B), that acts
to cool the torch and further thins out the dimensions of the plasma arc,
which at its centre (C), easily manages to reach the temperature of
10.000°C.
With new types of torch and with medium-low power levels (processes
that use less than 150A for cutting), today it is possible to use only compressed air as the cutting gas, as well as the cooling gas: the complete
process thus becomes much cheaper (Fig.6).

S30 TORCH
1.0 TECHNICAL DETAILS
2.0 INSTALLATION
The generator is fitted with a welding torch. The instructions
below refer to replacing a faulty torch and should be carried
out only by qualified personnel.
Switch off the power source.
3.0 SETTING UP FOR USE
Fig.1 Assemblaggio corpo torcia
Before starting work, it is necessary to carry out the following checks
and work:
1) Check that the generator is turned off.
2) Check that all the parts of the torch are working. For the various
parts that make up the torch body (Fig.1), the sequence of correct
assembly is 1-2-3-4-5.
3) To fit the electrode (No.2), use the key, taking care to avoid excessive tightening that could damage the thread of the components.
The electrode must be unscrewed only after the post-cutting air
flow is finished, and therefore with the electrode itself cooled.
4) Check that the air diffuser, or "swirl-bush" (No.3) is working correctly, which must always show access holes free of obstruction;
the use of a defective air diffuser would cause overheating, with
consequent damage to the components of the torch body.
5) With the spare parts assembled, check that by screwing the outer
nozzle (No. 5) to the torch body the corresponding alarm on the
generator is cut off; finally check that by unscrewing the nozzle the
alarm is triggered; these checks should be carried out with the generator on, taking care not to press the torch button.
6) The compressed air used must be filtered and maintained at a high
level of purity; humid air, oil and other contaminative agents must
be removed, by making use of suitable driers and anti- oil filters.
Thus the torch is set up for the cutting operation.
In any case it is necessary to also follow what is shown in the instruction manual for the generator, above all in the paragraphs
"General precautions", "Connecting up" and "Normal maintenance".
4.0 USING THE TORCH
4.1 Inclination and speed of the torch during cutting
The torch is generally held perpendicular to the workpiece during all
the cutting phases; obviously, whenever it is required to carry out
chamfering or inclined cutting, the torch must be tilted to a suitable inclination.
The speed must be adjusted so that the outflow of the arc below the
workpiece is perpendicular (5-10 degrees of slope are acceptable).
A slow speed start is advisable to prevent spray of material
which could damage the tip.
4.1.1 Puncturing
In some cases it is necessary to puncture a hole in the material using
plasma cutting. In this way, the wear on the parts which are subject to
deterioration will be increased, and it becomes very important to try to
work to avoid the return of spray, which can be dangerous, especially
with sheet metal over 5 mm. thick.
We suggest starting with the torch inclined sideways, so as to
point the spray outside the cutting area, avoiding damage
and overheating of the torch body.
Immediately remove any material accumulated on the tip
or on the ceramic hood.
Caution: plasma cutting is a process with a high thermal
element, which takes both the piece to be cut and the end
parts of the torch to extremely high temperatures.
4.1.2 Circular cutting
For the preparation of flanges and opening holes, it is possible to use a
pair of compasses, equipped with rotating heads and movement on
wheels.
4.1.3 Practical advice
We advise igniting the pilot arc away from the workpiece, and then
moving near until the cutting arc is struck; striking a cutting arc repeatedly and directly by contact with the workpiece creates an increase in
temperature of the torch body.
Avoid turning off the generator before the end of the post-cut
cooling flow, to avoid overheating of the components of the
torch.
5.0 MAINTENANCE AND INSPECTION
With the S30 torch, the ignition of the pilot arc takes place by pneumatic distancing of the electrode from the tip; during the operation,
oxidized area are created on the two components, that can give ignition problems.
The efficiency of the electrode is therefore not only determined by the
cutting time, but also by the number of starts of the pilot arc that are
made.
It is advisable to replace the electrode before the tungsten insert in the
point is completely worn out.
The tip has an average life similar to that of an electrode, and is replaced when an irregular hole is present which is larger than the nominal
one (this can cause slanted cuts of poor quality).
Electrode and tip are replaced simultaneously to prolong their active life.
Working with electrode and tip which are too spoiled can cause damage to the torch body.
It is important to pay special attention to the fitting of the electrode and
tip in order not to irreparably damage the torch.
