IntraTec Tip
The IntraTech ProPress 100 has the capability to
perform an automatic pressing cycle, which is ideal. To enable this
valuable function, follow these 3 easy steps:
•Press the ‘Special Function’ button and turn
the selector knob counter-clockwise to ‘Calibrate Oven,’ then press
next.
•The furnace now asks for a password: turn the selector knob
to ‘310’ and press next.
•Now it asks, "Use timed press?" Turn selector
knob to ‘No,’ then press next. After enabling this feature, go to
each pressing program and change the ‘Re-press’ time to match the
recommendation above.
Note: Finding the optimal pressing
temperature for each furnace is crucial. To determine the optimum
pressing temperature, perform the following "press-to- failure" test.
Lower the pressing temperature (step-by-step, usually 5° to 15° C)
over two to three pressings until a mispress (failure) is attained.
At this point, the last (previous) temperature at which everything
pressed completely is considered the optimal pressing temperature.
To make this experiment scientific and valid, work with only one variable
at a time; in this case, pressing temperature. Also, observe several
constants, including: entry temperature, rate of climb, hold time
and re-press time.
