2.2 Automatic operating mode
The Automatic operating mode has a 3-step temperature-time profile.
The temperature-time profile can be expanded by connecting an optional WHP3000 bottom heater.
When the WHP3000 is connected via the RS232 interface (22) the bottom heater is integrated into
the time profile.
The temperature profile is comprised of the following 3-steps:
Pre-heat phase, system
Step 1
(ends with an audible tone)
Pre-heat phase, component Step 2
Reflow process (soldering) Step 3
The soldering process is normally started with the hot gas nozzle raised. At the end of step 1 there
is an audible tone, after this tone the nozzle should be placed over the component in the soldering
position. At the end of Step 3, raise or remove the nozzle from the application.
The following pre-settings must be made on the WHA3000P controller to define a customer-specific
temperature-time profile.
