Pro 200 Series Furnace Operations Manual
11. Hold Temperature
Hold Temperature or the top temperature is the final,
highest temperature in a 1-Stage Program, and an
intermediate stopover temperature in a 2-Stage
Program.
The range of values is 400° C (752° F) to a maximum
of 1200° C (2192° F).
Rotate the Selector Knob to select the temperature
value, then push the Selector Knob OR press the
Next button to store the parameter.
12. Hold Time
Hold Time is the length of time the furnace stays at
the top Hold Temperature. If the Program is a 2-Stage
Program, there will be separate Hold Times for both
Hold Temperature 1 and Hold Temperature 2.
The range of values is 00 hours, 00 seconds, to a
maximum of 18 hours.
Rotate the Selector Knob to select the time value,
then push the Selector Knob OR press the Next
button to store the parameter.
NOTE: IF YOU ARE ADDING A 2-STAGE PROGRAM, THE
RATE RISE 2, FOLLOWED BY THE HOLD TEMPERATURE 2,
AND THE HOLD TIME 2 PARAMETERS WILL APPEAR HERE.
IF NOT, THE TABLE DOWN TEMPERATURE WILL APPEAR
NEXT.
13. Program Fusing Adjustment Parameter
IMPORTANT NOTE: THE FUSING ADJUSTMENT PROGRAM
PARAMETER IS SIMILAR TO THE HIGH FUSING ADJUST
AND LOW FUSING ADJUST FUNCTIONS FROM THE SPECIAL
FUNCTIONS MENU IN THAT ANY VALUE ENTERED HERE
WILL EITHER ADD TO, OR SUBTRACT FROM, THE HOLD
TEMPERATURE PARAMETER IN THE PROGRAM. THE
PROGRAM LEVEL FUSE ADJUST PARAMETER ADJUSTS
THE HOLD TEMPERATURE ONLY FOR THE PROGRAM IT
IS ENTERED IN, WHERAS THE SPECIAL FUNCTIONS/ HIGH
FUSING ADJUST AFFECTS ALL PROGRAMS WITH A HOLD
TEMPERATURE >800 C AND THE SPECIAL FUNCTIONS/LOW
FUSING ADJUST AFFECTS ALL PROGRAMS <800 C.
Why do you need program fusing adjustments?
The Program level Fusing Adjust is useful for making
minor adjustments to a single, specific Program
without altering the original Program design.
16. Use Argon*
Inert Argon gas may be required for firing or
sintering metals like Titanium to prevent oxidation.
If enabled; any time the table is closed and there is
no vacuum present in the muffle, the argon valve will
open to allow inert argon gas to flow into the muffle.
The default value for Use Argon is NO. If you wish
to use Argon select YES.
Rotate the Selector Knob to select the setting, then
push the Selector Knob OR press the Next button
to store the parameter.
*Argon is only on the Pro 200 and the option will only
show if it is enabled in the Special Function menu.
All furnaces have individual firing characteristics,
even with identical settings. The Special Functions
High/Low Fusing Adjustment features are useful for
matching the firing characteristics of two furnaces
so that they fire identically.
At the initial Program Addition, you will want to
use the original suggested Program parameters,
until your experience suggests a Program specific
adjustment is indicated.
Select either UNDERFIRES OR OVERFIRES by
rotating the Selector Knob, then push the Selector
Knob OR press the Next button and leave the
default value of 0 Degrees, then push the Selector
Knob OR press the Next button again. You can
come back later and Edit the Program level Fusing
Adjust parameter.
14. Table Down Temperature
The Table Down Temperature is the temperature
at which the table will open after the Hold Time
expires.
The range of values is 25° C (77° F) to a maximum of
the final temperature.
Rotate the Selector Knob to select the temperature
value, then push the Selector Knob OR press the
Next button to store the parameter.
15. Cool Time
The Cool Time parameter specifies the length of
time the table takes to go from the full up position
to the full down position, with several intermediate
pauses along the way.
The range of values is 00 minutes, 00 seconds, to a
maximum of 99 minutes.
Rotate the Selector Knob to select the time value,
then push the Selector Knob OR press the Next
button to store the parameter.
