Operation
Preheating
Premelting is necessary to keep the "cast delay
time" (time to melt the alloy after insertion of the
mould) as short as possible.
1.
Align the crucible with the center of the crucible
coil by turning the casting arm and moving the
the slider back and forth.
2.
Lift the crucible coil. Pull the handle located on
the right exterior side of the device forward for
this purpose.
3.
To avoid fusing, the knob must be set to up to
50% according to the alloy-specific value. The
setting controls the switching of the heater on
and off according to the measured IR radiation
of the alloy.
4.
The preheating process is started by closing
the cover.
The "heating" button will light up to indicate
that the heating process is in progress
5.
Open the cover to stop the premelting process.
The heating process will be interrupted.
WARNING
Never look into the melt without
protective glass and protective
eyewear!
NOTICE
ATTENTION!
• Do not premelt the alloy for too long as this may
result in uncharacteristic behaviour of the alloy
later on.
During the premelting process, the castings
should only deform slightly and not melt com-
pletely!
• As these are only reference values, the cast-
ings must be observed. If the castings deform
more than just slightly, the premelting process
must be stopped (and the value setting must be
reduce with the knob).
• Do not move the handle to raise/lower the cru-
cible coil during the premelting process as this
will initiate the spinning process prematurely!
