MCH_HQ00
Casting power setted (min 260 –max 440)
Temperature to be reached
Metal temperature measured
Power output (min 260 –max 440)
Power output on the crucible ( kW)
Current measured on the power circuits
This sign appears only when the machine si not heating. It
disappears when the casting is in ON.
Power mosfet temperature (°C)
Water cooling temperature (°C)
This symbol indicates that the machine is heating.
Generator status (OFF = not powered, ON= powered)
Heating status (STOP = not active, START = active)
It appears sometimes during the heating. Not relevant
It appears if the coil is down or if the casting protection
grid is open. When CR1 is present is not possible to start
casting
It is possible to set the parameters as below:
1. For changing the casting power press the parameters
selection button (3, pict.3) until the “>” symbol is visible near
to the P parameter:
or until the symbol is near to the T parameter to set the
casting temperature.
2. Rotate the encoder (2, pict.3) to change the parameter value.
Working parameters could be changed also when the casting is
ON: they are immediately executed.
1. Place the main switch (3, pict.1) at the position ON.
2. Turn on the automatic safety cut-out (6, pict.1).
3. Press the ON button (4, pict.3)
4. Set the working parameters as indicated in previous section.
5. Press the ON generator button (6, pict. 3): the OFF indication
on the display will disappear and it will be shown ON.
6. Put the crucible into its hole. Put the metal inside the crucible.
7. Lock the crucible with the crucible lock lever (2, pict.1)
8. Close the cating area protection grid (5, pict. 1)
9. Put the coil lever (10, pict.3) in up position: the casting coil will
rise up. If the coil doesn’t move, please check that the
machine is connected to the external compressed air supply.
10. Press the casting on button (8, pict.3) for start the casting.
Now the machine will start heating until the metal reach the
temperature setted. On the display the TEMP parameter will
shown the temperature of the metal.
When the metal is ready to be casted:
a. open the casting area protection grid (5, pict.1): casting
will be immediately stopped.
b. put the coil lever (10, pict.3) in down position.
c. Hold the crucible tipping lever (12, pict.1), pull with it the
crucible support, and after rotate the lever to pour the
crucible.
To stop in any moment the casting you can operate in one of the
following ways:
a. Open the casting area protection grid (5, pict.1)
b. Put the coil lever in down position (10, pict.3)
c. Press the casting OFF button (9, pict.3)
d. Press the generator OFF button (7, pict.3)
In all these situations the haeting will be stopped (STOP indication
on the display) and, except the (c) case, it will be also deactivated
the generator (OFF on display). To restart casting repeat the
wroking procedure from item (5).
NOTE: NEVER SWITCH OFF THE MACHINE (by pressing OFF
button (5, pict.3) or by puttin in OFF position the automatic safety
cutout (6, pict1) or the main swicth (3, pict.1)) WHEN THE COIL
IS UP AND WITH A WARM CRUCIBLE INSIDE. Risk to damage
the heating coil.
The reader is pre-set for all types of alloy. It is only necessary
to move a switch on the reader itself when the alloy has a very
high platinum content.When you wish to melt these types of
alloy slightly unscrew the four screws holding the cover. Move
the switch as shown in figure 6.
Always check that the mirror and the lens of the reader is
completely clean. The mirror is easy to get at. The lens is in a
horizontal position towards the instrument (fig. 6).
Fig. 6
Do not tamper with the two screws under the temperature
setter display.
Use very clean metal making sure that the recast heads are
sanded properly in such a way that all traces of coating that
could cause porosity are removed. Do not melt metals
covered in oil or grease etc.
Never leave the hot crucible in the heating coil of a machine
that is completely off and, generally, whenever water is not
circulating (lack of water, no power).
While melting inside the heating coil is under way, a high
frequency current flows through the metal.
Under no circumstances touch the coil or metal with hands or
metallic objects since you would risk getting a shock that while
not being dangerous is unpleasant.
Note:only use ceramic stirring rods to mix the metal while it is
melting.
