3. DESCRIPTION OF THE UNIT
The machine for centrifugal casting LC-CAST 600is
designed for induction high-frequency casting of Co-Cr,
Ni-Cr-Mo and precious alloys used in dentistry.
The melting is inductive and normally 30 g of metal are
melted within 1 min (in automatic mode).
The induction coil is lifted and dropped by an electric
motor. Cooling is autonomous.
For experienced users there is a possibility for manual
control of the melting/casting process in order to
optimize the conditions and to obtain best results.
The temperature of the generator is monitoring by built-
in sensor. In case of malfunction of the cooling system
the process is interrupted automatically.
The status of the machine is indicated on the display.

4. INSTALLATION AND INITIAL START-UP
Place the machine on a solid foundation.
By means of wrenches №14 and №19 (for
adjustment of the feet) and a level adjust the
machine so that the centrifugal arm is
horizontal.
This adjustment will reduce the vibrations when
casting.
Make sure that the mains voltage is ~230VAC.
The plug which the device is equipped with is
mono-phase and strengthened.
The respective contact is supplied together with
the device. Fit it on installation with a conductor
4mm2in thickness as it is recommended to be
on a separate circle with fuse 35А.
The contact must be earthed reliably.
Make sure that there is water in the container (9
liters).
Connect the plug into the socket.

5. PRACTICAL USE
5.1. PRESETTING
NOTE:
CAUTION!
To ensure the normal operation of the apparatus before
each casting procedure balance of the arm must be made
depending on the certain weight of the used muffle and
the quantity of the metal needed for the casting. For this
purpose you must keep the following steps:
Loosen the cross-shaped handle (18) until you feel
that the arm can move freely;
Put the muffle into the bed (12);
Put the crucible into the stand (13).
When melting precious metals the usage of graphite
insert is obligatory.
Put the necessary quantity of metal into the crucible;
By means of the regulating handle (14) and the stop
limiter (15) adjust the orifice of the crucible to match
the pouring cone of the muffle but without touching
it;
Slide the carriage (16) to the position most close to
the muffle;
Move the counterweight (17) by rotating it until
balance of the mechanism is achieved;
The non-balance resulting from the shift of the
molten metal away of the crucible to the muffle
during the process of casting is compensated by
rotation of the counterweight in direction opposite to
the muffle.
This adjustment described is essential for avoiding of the
vibrations of the apparatus when melting.
By means of MPK adjust the starting momentum of
the centrifuge;
Come into position of the crucible over the inductor.
When the position is correct you will hear an
interrupted sound. Lift up the inductor by pressing
the button LIFT;
Close the lid in order to start the melting.
Watch the melting process through the window of
the upper lid, and if the metal is ready for casting,
press LIFT.At this point the inductor goes down and
rotating mechanism starts turning;
Casting ends after expiring the preset time or after
pressing STOP. During the casting lid is locked.

5.4. INFORMATION SHOWN ON THE DISPLAY
LED INDICATORS ON THE FRONT PANEL
There are two modes of melting - automatic and manual
- and they are chosen from the menu of the machine in
the submenu
SETTINGS> MELTING
The normal is automatic mode. In this mode the unit
operates with maximum power and the melting is the
fastest one.
In manual mode the operator can reduce the power of
generator by turning the MPK. The value is displayed as a
percentage of maximum or as a progressive bar.
For this process the machine uses the principle of
centrifugal casting. Casting starts by pressing the LIFT
button.
The force of acceleration, which is applied during the
casting could be changed before melting when the
inductor is in lower position. This is done by rotation of
the MPK. The value is displayed as a percentage of
maximum or as a progressive bar.
The time for casting is preset, but the process, if
necessary, may be terminated by pressing STOP.
To ensure the safety of the machine during the casting
upper lid is locked and unlocks after completing the
process.
The casting machine LC-CAST 600 has a large display and
LED indicators which show the work necessary
information and machine status.
Indicator 18 –the upper lid is locked / unlocked;
Indicator 19 –indicators for position of the inductor and
for generator working.
Up and Down arrows –the inductor is up or down.
When the down arrow lights and up arrow flashes -
inductor is lower position and can be lifted.
When the generator is working LED in the middle lights.
Indicator 20 –indicator for the cooling system.
Indicator 21 –indicator for casting process.
Indicator 22 –indicators for the upper cover.

7. IMPORTANT PRACTICAL INFORMATION
Use only VOP crucibles or similar.
Before perform a casting you could warm up the metal in
the apparatus until it become red. This will reduce the
melting time. Do not heat the metal in muffle furnace.
Avoid placing of the machine in the immediate vicinity of
heat sources (radiators).
Avoid placing any objects on the apparatus body.
Regularly check the water in the tank as for this purpose
you open the left lid by a special switch.
Clean the rest of metal carefully as you look out for metal
particles not to fall into the brass pipes of the inductor.
The windings of the inductor should not come into
contact.
Clean the isolating plates of the inductor only with a dry
towel without using of water or any solvents.
The lifting and carrying is made with the help of special
handles mounted on the relevant places of the body. the
machine should be carried only by 4 persons.
No carrying and transportation in another state except
for vertical position is allowed!
