Starting Program Execution; Control Of The Vacuum Function; Saving And Loading Temperature-Time Profiles - Weller WHA3000V Operating Instructions Manual

2.4 Starting program
The soldering process and thus the 3-step temperature-time profile is started:
Directly on the Control Panel:
2-Position Foot Switch (21):
Manual Control Console (21):
(Optional)
The nozzle temperature, air flow rate and the time remaining are indicated on the display (1). The
active program step is marked on the display.
When the hand-piece is placed in the safety stand, the program is interrupted and the hot air
switched off by an integrated contact. When the nozzle pre-heating is active (PREHEAT ON), the
device switches to the standby mode with reduced temperature and air flow rate.
Note: When using the WBH 3000S Circuit Board Holder (20), the WHA 3000V will
automatically turn "off" if the position of the Z-axis Head is moved from the "Locked" center
position. It must remain in position directly over the Hot Plate to allow for the WHA 3000V to
operate.

2.5 Control of the vacuum function

The nozzle vacuum are activated:
Directly on the Control Panel:
2-Position Foot Switch (21):
Manual Control Console (21):
(Optional)
If the VAC Control Key (11) is pressed prior to the start of a de-soldering process, the
vacuum integrated into the nozzle is activated automatically at the end of the process. The
vacuum function can also be enabled and disabled manually at any time during the
soldering process. If the vacuum is enabled during a soldering process, there is no
automatic activation at the end of the process.
Note: If the nozzle temperature is above 250°C/482°F the vacuum is automatically disabled
after 90 sec for safety reasons.

2.6 Saving and loading temperature-time profiles

A total of 10 temperature-time profiles can be saved. A default profile is saved in the 10 program
memories in the factory.
Press UP/DOWN Control Keys (2)/(3) simultaneously until the following menu appears on the
display (1)
START/STOP (10) Control Key, LED (9) illuminates.
START/STOP corresponds to setting 1 of the foot switch
(hot air and vacuum are only active when pressed)
Foot Switch Position 1-Air, Position 2-Vacuum
START/STOP using the AIR Control Key
VAC (11) Control Key, LED (8) illuminates.
vacuum corresponds to Position 2 of the foot switch
using the VAC Control Key
