The Program Parameters (shown in Fig. 6-8) can be adjusted to desired levels within
certain minimum and maximum values. Programs 1-3 are factory defaults for running
common fuming cycles. The parameters can be modified in the first three programs,
and a cycle ran; however, the modifications will not be saved, and will revert back to the
factory default parameters. Programs 4-20 will save modifications to the program
parameters. The modifications will be saved once a cycle has begun.
To browse through the programs, move the red arrow to PROGRAM # using
[UP/DOWN]. Then, use [RIGHT/LEFT] to change to the desired Program #.
The CA Fume Parameters can be selected by using [UP/DOWN] to highlight the
desired parameter, then use [RIGHT/LEFT] to change the selected parameter value.
The parameters are described below:
Grams CA Min – 0.0 Max – 99.9
This parameter is for user reference only, and will be displayed on the following screen
just before the Fuming Cycle is initiated. Reminds user how much CA to place in the tin
to achieve consistent development results.
Humidity Min – 20 % Max – 80 %
This parameter sets the desired level of relative humidity the chamber will achieve
before entering the Fuming stage of the program. Adding humidity to a desired level
rehydrates prints, which allows for better CA polymerization, which improves print
development. Set in 1% increments.
RH Dwell Min – 0:00 Max – 99:30
This parameter sets the desired dwell time between when the desired relative humidity
level is reached in the chamber, and when the Fuming portion of the program begins. If
set to 0:00 the Fuming portion will begin immediately after the desired relative humidity
level is reached. Set in 30 second increments.
CA Heat Min – 100 OF (38 OC) Max – 425 OF (218 OC)
This parameter sets the temperature of the hot plate upon which the tin of CA will be
placed. CA volatizes quickly around 170 OF (77 OC); however, some users prefer higher
temperatures to expedite volatizing of CA fumes. Set in 1 OC (~2 OF) increments.
Fume Min – 0:00 Max – 99:30
This parameter sets the duration of the Fuming stage. Time begins on this stage when
the Hot Plate turns on, not when the desired temperature is reached. Set in 30 second
increments.
Purge Min – 4:00 Max – 10:00
This parameter sets the duration of the Purge, or Exhaust, stage of the program. Under
ideal conditions with nominal CA glue in the glue tin, chamber purges completely in 4
min. Set in 30 second increments.
