20. VACUUM RELEASE – DURING HEAT UP is displayed.
Turn the
Select Knob
to select DURING HEAT UP,
DURING HOLD TIME, or DURING COOLING. DURING
HEAT UP will release the vacuum at a temperature
during the heat rise step.
DURING HOLD TIME will release the vacuum after a
time during the hold time step.
DURING COOLING will release the vacuum at a
temperature during the cooling step. Press the
Next
button.
If DURING HEAT UP was selected, the temperature
you wish to release the vacuum will be displayed. The
furnace will purge to an inert condition at this point.
Press the
Next
button. The program has been saved
and the display will return to the Ready Select Menu
screen.
If DURING HOLD TIME was selected, the time during
the hold time that you wish to release the vacuum will
be displayed. In this example the furnace will purge
to an inert condition 30 seconds into the hold time
step. Press the
Next
button. The program has been
saved and the display will return to the Ready Select
Menu screen.
If DURING COOL TIME was selected, the temperature
you wish to release the vacuum will be displayed. The
furnace will purge to inert condition after the heat
rise step, the hold time step, and at this temperature
during the cooling step. Press the
Next
button. The
program has been saved and the display will return

Sintering Firing Cycle Program
(Pro 100 Only)
The sintering firing
cycle on the
Pro 100
provides for inert
conditions throughout
the firing cycle to
reduce or eliminate the
oxide buildup on the material. The dual
heat rates allow the furnace to burn off the binders at low
temperatures and then sinter the metals at a high rate of
rise. Argon must be properly hooked up to the furnace
before this program type is run. See page 33 for details.
Procedure:
1. Press the
Change Program
button.
2. Turn the
Select Knob
until ADD A PROGRAM

must expire before entry time begins. The time
is displayed in minutes: seconds. The table will be
raised in steps evenly spaced during entry time.
Press the
Next
button.
8. ENTRY TEMP XXXC is displayed. This is the tempera-
ture at which the porcelain enters the furnace. Press
the
Next
button.
9. SOAK TIME X:XX is displayed. Select the time to
hold the work at the entry temperature. Press the
Next
button.
10. 1ST RATE XXC/M
is displayed. This is the desired first
heat rate for this program. This heat rate is usually slow
to burn off the binder materials. Press the
Next
button.
11. 1ST TEMP XXXC is displayed. This is the desired first
temperature for this program. At this temperature the
furnace will switch to the second heat rate until it
reaches the final temperature. Press the
Next
button.
12. 2ND RATE XXC/M is displayed. This is the desired
second heat rate for this program. This heat rate is
usually fast to reach the sintering point of the metals.
Press the
Next
button.
13. FINAL TEMP XXXC is displayed. This is the final
temperature for this program. Press the
Next
button.
14. HOLD TIME X:XX is displayed. This is the time that will
hold the porcelain at the final temperature. Press the
Next
button.
