The hot crucibles, pestles and muffles may only be deposited on a heat-resistant and fire-
proof base, like crucible support.
•
Make sure to use the device only for melting metals and alloys in the crucibles meant for
this purpose.
•
Don’t melt any material, generating toxic gas.
•
The generator (function „melting material“) may only be switched on if the melting material
is already in the device.
•
When the heating is on, don’t touch the inductor chamber with your hands or other things.
•
Use pliers when inserting or taking out the muffle, mould or handling the thermoelement
because of danger of being burnt.
•
Only open the casting chambers when there’s no excess pressure or under pressure.
•
Be careful regarding handling gas bottles. Secure against falling down, don’t heat, handle
with care.
•
The heating process incl. casting process may only last max. 3 minutes.
Alloys with a longer melting time are inadmissible.
•
The rest time between a casting and starting a new heating process has to be at least 6
minutes. There may be no hot crucible in the device during this time. The muffle chamber
as well as inductor chamber have to be open for cooling reasons during this time.
•
Entering the casting temperature for non-precious metals generally corresponds to
recommendation of the metal-suppliers. These recommendations are without engagement.
•
Tip: several (approx. 5 castings) should be performed visually, possibly with different
temperatures, and in case of a good casting result the casting temperature should be
adopted results-oriented as a set value for a casting program.
•
Regarding temperature measurement small metal quantities below 15 g are not
precise due to a lack of quantity and are difficult to cast. If false castings are
produced, often default imbedding or a wrong temperature assessment of the
metal melting is the reason.
•
When processing non-precious metals and palladium-containing alloy in the
ceramics crucible, temperature measurement is only possible with the „Longlife -
pestle“.
Generally noble metal (NM) is molten in the graphite crucible, if applicable in the ceramics
crucible with the graphite seal pestle.
•
When melting thin and few split noble metal pls. pay attention that they don’t
position vertically as there’s no coupling possible and the metal consequently
won’t melt. Therefore push together split metal, put old sprue onto the new
material or weld split metal together or spot-weld.
