5. Confirm the preheating process with "OK".
For some alloys, the preheating process may
be skipped with a second button.
The chamber is evacuated during preheating.
The preheating may last for up to 60 seconds.

NAUTILUS

T will display a "Preheating pro-
cess completed" window to indicate the end of
the preheating process.
Please note:
• Preheat precious-metal and Pd alloys with /
without crucible insert until the first alloying
components deform, but do not melt.
• Preheat CoCr and NiCr alloys until the alloying
components glow bright red; the alloying com-
ponents are still solid.
Important: Do not preheat for too long as the
alloy will melt otherwise. The moment the last
solid alloying component is sinking into the melt is
important for starting the timer!
If no video image is shown on the screen, the
message "Temperature too low" will appear. As
soon as the camera detects an image, it will be
transmitted to the screen.
