When you melt alloy and cast using a ceramic crucible, we do not recommend

Ceramic Crucible you to use the ceramic crucible over the maximum allowed casting cycles.
Do not insert red hot crucible into the crucible counter.
This causes the trouble.
1. Use the reverse tongs provided to grip the inside of ceramic crucible and
Check Casting Cycles
set the crucible in place to press the CAST CYCLES button.
2. The displays will show
while the crucible rotates for approx.
10 seconds to read the bar code on the crucible. The 4 digit display shows
the crucible No. and the 2 digit display shows the cast cycles of the crucible
already used.
3. If the cast cycles are over the maximum allowable limit, the numbers of
cast cycles used and
will appear alternately on the 2 digit display.
As we do not recommend the continued use of the crucible that exceeded
allowable cycles, replacement of crucible is recommendable and repress
the CAST CYCLES button.
Note If you accidentally check a wrong crucible other than the, one you intended to use,

press the CLEAR button and press the CAST CYCLES button after inserting a
correct crucible. If you melt alloy with a different crucible than the one you checked,
the cycle numbers will be added to the unused crucible. And if the cycle numbers
exceeded unnoticedly, the continued use of the crucible may have a crack.
Note If you use a crucible with no bar code or you don't check cycle numbers or check

should be used.
If the same crucible is used consecutively for melting, there is no need to do the
crucible check repeatedly. The unit will automatically recognize it as the same
previous one used for casting.
The unit keeps memory of crucible cycles used and crucible number and cycle

to 10 cycles of castings.
A ceramic crucible cycle is counted as follows ;

We recommend you to make visual checks of ceramic crucible
before use for surface cracks or the crucible is malformed or not,
regardless of its restricted cycles. If anything abnormal found,
do not use the crucible.
