Limits of use (IEC 60974-1)
The use of plasma equipment for cutting is typically discontinu-
ous as it consists of periods of effective operation (cutting) and
rest periods (while the piece is being positioned, etc.). The size
of the equipment is suitable for safe use of max. nominal cur-
rent I2 for a working time that is 40% of the total time of use.
The regulations in effect stipulate that 10 minutes is the maxi-
mum total time of use. For the work cycle, 40% of that time is
considered. Exceeding the permitted work cycle triggers the
intervention of a thermal protector which protects the inter-
nal components of the plasma cutting plant against dangerous
overheating. The intervention of the thermal protection is indi-
cated by powering on the yellow LED sited on the rack panel.
After a few minutes the thermal protection automatically re-
sets, the yellow LED goes off and the plant is ready for use
once again. This plant is built to have a protection level of IP
23 S, which means:
•
That it is protected against the penetration of solid foreign
bodies with diameters in excess of Ø 12 mm.
•
That it is protected against water spray hitting the surface
with an angle of incidence up to 60°.
•
That the plant has been tested for withstanding harmful ef-
fects due to water getting in when the moving parts on the
equipment are moving.

is the responsibility of the installer or user of the equipment to
ensure, by consultation with the distribution network operator
if necessary, that the equipment may be connected.
How to lift up the machine
This plant has a handle specifically for carrying the machine
by hand.
NOTE: These hoisting and transportation devices conform to
European standards. Do not use other hoisting and transpor-
tation systems.
Opening the packaging
The unit comprises the following main items:
• SHARK 35 plasma cutting unit.
•
Plasma torch with direct connector built into the plant, and
consumable “starting kit”.
• Earth cable.
• Trolley for transportation (optional).
On receipt of the unit, perform the following operations:
• Remove the plasma cutting unit and all relative accessories
and components from the packaging.
•
Check that the plasma cutting unit is in good condition. If it is
not, inform your dealer immediately.
•
Make sure that all the ventilation louvers are open and that
the airflow is not obstructed.
Plasma cutting
The cutting system used by this equipment is a low current sys-
tem that uses compressed air as its plasma equipment as well
as for cooling. The air normally used is a mixture of 79% nitro-
gen and 21% oxygen. These two biatomic gasses have almost
identical enthalpy and form a highly energetic blend. The low
current also makes it possible to use torches with a low air ca-
pacity and moderate cutting speed, that are more suitable for
manual procedures.
CUTTING PARAMETERS
In analyzing the parameters that characterize manual plasma
cutting it is necessary to note that they depend on the material
to be cut, its thickness and the skill of the operator in following
the cutting line. Optimum speed depends largely on the skill of
the operator and amount of material to be cut and is achieved
when the fused material flows through the groove and is not
projected in the direction of the torch. If the latter occurs, cut-
ting speed has to be reduced.
The parameters that affect cutting are:
•
Electric power. Any increase in electric power will permit
higher cutting speed and greater thickness of the material
to be cut
• Compressed air capacity. Increasing the air capacity ena-
bles cutting thicker material and ensures better quality at
any thickness
•
Distance between nozzle and piece. The appearance of the
cut and wear of the active components of the torch depends
on the nozzle being held as a correct distance from the piece.
NOTE: The width of the cutting groove is usually about twice
the diameter of the hole in the nozzle.
Respect of the above recommendations ensures greatly redu-
ced thermal alterations of the material due to cutting, that are in
any case always fewer than those caused by oxygen torches.
The thermally altered zone is in any case smaller than the zone
on which the weld is effective, so that in welding pieces that
have been cut by plasma it is not necessary to perform any
cleaning or grinding operations.

Installation
The place where the equipment is installed should be selected
with care so as to ensure satisfactory, safe use.
The user is responsible for installation and use of the equip-
ment according to the instructions provided by the manufac-
turer in this manual.
Temperatures must be between -25 °C e +55 °C. during trans-
portation and/or storage in stores.
Before installing the equipment the user should take into con-
sideration any possible electromagnetic problems in the work
area.
In particular, we recommend that the equipment not be installed
in the vicinity of:
• Signalling, control and telephone cables.
• Radiotelevision transmitters and receivers.
• Computers or controlling and measuring instrument.
• Safety and protection devices.
If the operator wears a pacemaker, hearing aid or other sim-
ilar device, he should consult his doctor before approaching
the equipment while it is running. The environment where the
equipment is installed must conform with the degree of protec-
tion of the chassis that is IP 23 S (IEC publication 60529). The
system is capable of working in environments where working
conditions are particularly hard.
This equipment cools water by forced circulation of air and must
therefore be positioned in such a way that the air can easily
be drawn in and expelled through the openings in the chassis.
Connection to the electrical
supply (Fig. A)
Connection of the machine to the user line (electrical cur-
rent) must be performed by qualified personnel.
Before connecting the cutting equipment to the mains sup-
ply, check that the data on the machine plate correspond
to the supply voltage and frequency and its main switch
is on the “O” position (Pos. 1, Fig. A).
Connection to the power supply must be effected using the plug
provided with the cutting plant (Pos. 2, Fig. A).
Proceed as follows if you have to replace the plug:
•
2 conducting wires are needed for connecting the machine
to the supply
•
The third, which is YELLOW GREEN in colour is used for
making the “EARTH” connection.
Table 2 shows the capacity values that are recommended for
fuses in the line with delays.

Pos. 3 Yellow LED with dual function and protection: THER-
MOSTAT and OVERCURRENT.
• THERMOSTAT function: this LED shines to indi-
cate that the overheating protection has cut in be-
cause the work cycle is not being followed. After
several minutes the overheat cut-off rearms auto-
matically (and the yellow LED turns itself off) and
the welder is ready for use again.
•
OVERCURRENT function: this LED shines to
indicate that the overcurrent protection has cut in
because the current has reached hazardous lev-
els. The machine stops automatically. Switch off
the machine by turning the power supply switch
(Pos. 4, Fig. B) to position “O” and switch it on
again after at least 5 seconds.
Pos. 4 GENERAL WARNING SIGNAL yellow LED. This
switches on under the following conditions:
Switched on and flashing
•
External nozzle on the plasma torch missing or
screwed on incorrectly.
•
Consumables (external nozzle holder, nozzle, elec-
trode ecc.) on the plasma torch fitted incorrectly
or worn.
•
In case of an anomalous short-circuit on the plant’s
secondary circuit.
Switched on and steady
•
No compressed air or insufficient pressure (prob-
lems with the air compressor in the plant).
Pos. 5 Red PLASMA CUTTING CYCLE CHECK LED. This
LED switches on when the torch button is held down.
The plant is therefore ready for the cutting operation.
It switches off when the torch button is released.
Pos. 6 Two position control:
•
CUT - The switch must be moved to this position
whenever you want to cut.
•
AIR CHECK - The switch must be moved to this
position whenever you want to carry out a test to
check that air is present.
Connection of plasma torch
and ground wire
IMPORTANT: Before performing any operation regarding con-
nection of the torch and ground wire, disconnect the power to
the system.
IMPORTANT: Do not connect to the Plasma equipment any
other torch different from the standard supplied unes; the utili-
sation of other non suitable torches might be dangerous for
the operator.
The plasma torch is connected directly to the plant (Fig. D).
To obtain elevated cutting quality, the torch must transform the
power generated by the plant into a high energy density plas-
ma jet, so that it can efficiently melt metal and guarantee suffi-
cient strength to remove the meted part from the cutting zone,
impeding the formation of burrs. The torch is this a fundamen-
tal, indispensable component of the plasma cutting plant.
The standard supplied Plasma torch has special CEA elec-
trical connections. Before fitting a new equipment, make
sure that the torch connectios are matching the ones of
the Plasma equipment.
Connect the earth cable to the rapid coupling on the positive
pole as indicated in figure D.
The ground wire has to be connected on the specific terminal
to the piece to be cut, which must be effectively grounded
as well as the cutting bench. Do not connect the ground ter-
minal to the piece of material to be removed.
WARNING: The work area must be free of oil, paint, and rust!

IMPORTANT: Before switching on the equipment follow these
instructions carefully:
• Make sure the voltage and frequency of the supply network
correspond to the data on the rating plate.
• Make sure all the torch components are correctly installed.
•
Do not point the torch toward yourself or other persons near-
by. If switched on accidentally the pilot arc spark would ignite
and cause dangerous burns.
- 1 -
Turn the power supply switch (Pos. 4, Fig. B) to position 1.
- 2 -
The plant has just been started, and only the white LED that
shows that the mains power supply is on (Pos. 2, Fig. C) must
stay on the rack panel. The plant’s internal check runs a se-
ries of programmed tests, during which the fans and compres -
sor switch on for a few seconds and air comes out of the torch.
It is not possible to cut during this initial period, which lasts
about 10 sec.
- 3 -
Move the switch (Pos. 6, Fig. C) to the AIR CHECK position
and run the test to check that air is present.
WARNING: The air comes out continuously, the compressor
and fans are switched on!
- 4 -
Move the switch (Pos. 6, Fig. C) to the CUT position to be able
to begin cutting operations.
- 5 -
Adjust the electric current for cutting using the current regu-
lation knob (Pos. 1, Fig. C). Increasing the current will permit
higher speed cutting or, at the same speed, cutting of great-
er thickness.
- 6 -
Before starting to cut, effect a power on, moving the torch but-
ton protection upwards (Part A, Fig. E), and holding the torch
button down (Part B, Fig. E), for several seconds until the cut-
ting arc comes on. Avoid contact with the metallic item!
WARNING: After starting the plant or after the end of the post
airflow phase, the first time the pilot arc switches on this takes
more time for the plant to carry out the necessary electronic
and pneumatic tests.
- 7 -
To start cutting, press the torch button again, lighting the pi-
lot arc and starting air expulsion. During the cutting phase the
white LED that indicates that the power supply is on (Pos. 2,
Fig. C) and red LED that indicates that the plasma cutting cycle
check is running (Pos. 5, Fig. C) remain on on the rack panel.
CUTTING FROM THE EDGE OF A PIECE (Fig. F)
A) Position the torch, in a vertical position, on the external
edge of the item to be cut. In particular cases of extinction
of the arc at the entrance of the item to be cut, increase
the angle between the item and the metal by 95°.
B) Begin cutting from the external edge of the item until the
arc has fully traversed the same.
C) During the cut the nozzle may be kept in direct contract
with the item being cut. Do not hold the pilot arc on in the
air to avoid wasteful wear on the electrode and the nozzle.
CUTTING FROM WITHIN AN ITEM (Fig. G)
A) Cut with the torch in an angular position with respect to the
item, the rotate slowly until perpendicular to the metal.
B) When sparks appear from the lower part of the item, this
indicates that the cutting arc has completely perforated the
item to be cut; The bore has been created and now the cut
can proceed. If the sparks and/or residues spray upwards,
this indicates that the torch is being moved too rapidly. Re-
duce cutting speed.

7
CUTTING WITH PROLONGED ITEMS
This technique is used to cut in poorly accessible positions such
as angles, hollows, channels, etc.
Consumables are used at a higher rate with this technique.
CUTTING OPEN GRID OR PERFORATED PLATES
It is possible to cut open grid or perforated plates, by setting a
cutting current greater than 15A (from 15A to 30A).
When the torch button is pushed, if the operator goes out of
the workpiece during cutting, the pilot arc ignites again auto-
matically, to allow cutting to continue. Cutting done in open grid
mode gives rise to more wear of consumables.
IMPORTANT: Precautions to be taken to cut correctly and ef-
ficaciously:
• Always cut moving the torch gently to achieve a stable, pre-
cise cut.
•
Always cut moving the torch towards you which is simpler
than cutting while pushing or moving away from yourself.
•
Do not press or apply pressure to the torch during cutting
operations.
• Always use a line of reference for straight cuts.
•
To execute circular cuts, we recommend application of the
specific compass (supplied upon request).
- 8 -
Completion of cutting operations. The compressor continues
to functions for some 30 seconds to consent the torch compo-
nents to cool after the arc is extinguished (“post flow” function).
The useful life of consumables is prolonged in this manner. Wait
for the air flow to cease before powering off the plant. During
this phase you may start a new cutting cycle: press the button
to restart the pilot arc.
- 9 -
Turn the power supply switch (Pos. 4, Fig. B) to position “O”,
thereby switching off the plant.
- 10 -
When the operator switches the machine off, by pushing the
power supply switch (Pos. 4, Fig. B):
• White power supply on LED (Pos. 2, Fig. C) stays lit.
• Yellow thermostat indication LED (Pos. 3, Fig. C) stays lit.
•
During this period the microprocessor checks correct func-
tioning of all the components.
• Once this checking operation has been completed (duration
approx 5 sec.) the plant switches off.

Maintenance
WARNING: Before effecting any internal inspection of the
SHARK 35, interrupt the mains power supply.
SPARE PARTS
Original spares have been specifically designed for our equip-
ment. The use of spares that are not original may cause vari-
ations in the performance and reduce the safety level of the
equipment. We are not liable for damage due to use of spare
parts that are not original.
PLASMA CUTTING PLANT
As these systems are completely static except for the fan that
is, in any case, provided with self-lubricating bushes, only the
following operations are necessary:
•
Periodic removal of accumulations of dirt and dust inside the
plant using compressed air. Do not point the jet of air directly
at the electrical parts as this could damage them.
•
Periodical inspection for worn cables or loose connections
that could cause overheating.
•
Make sure the air circuit is completely free of any impuri-
ties and that the connections are tight and free of any leaks.
In this connection, inspect the solenoid valve very carefully.
COMPRESSOR
SHARK 35 does not require an external compressed air sup-
ply as it contains an integrated air compressor which requires
efficacious periodic maintenance to correct and fully explete
its’ function.
Compressor maintenance is limited to cleaning the air filter
which must be dismounted (unscrew and pull it outwards - see
Fig. H) regularly.
Possible problems and remedies
NOTE: Given the technical knowledge required to repair the
plasma cutting plant, in the case of breakage we recommend
contacting qualified personnel or our technical assistance ser-
vice.
The 4 indicator LEDs, located on the SHARK 35 rack panel,
enable, in most cases, identification of the cause of the fault.
We therefore recommend you check the LEDs to identify the
fault.
The faults possible in this plant are listed below with the proba-
ble causes, how to diagnose the same and how to solve prob-
lems rapidly and autonomously. If, however, the fault or problem
remains, contact our technical assistance service.
