(Optional)
When the hand-piece is placed in the AKT30 Safety Stand (17), the hot air is switched off by a Mirco
Switch. If the nozzle pre-heating is active (PREHEAT ON), the device switches to the standby mode
with reduced temperature and air flow rate (200°C / 392°F – 5l/min).
Note: Hot air is automatically disabled after 999 sec for safety reasons.
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 WHP 3000 bottom heater.
When the WHP 3000 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
Pre-heat phase, component Step 2
Reflow process (soldering)
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 WHA 3000P controller to define a customer-specific
temperature-time profile.
Settings step 1 – step 3

Time for the program step
The Automatic operating mode can be selected by pressing the AUTO/MAN Control Key.
The light emitting diodes (LED's) (13) indicate the related operating state.
