We thank you for the confidence you have shown by purchasing the Weller WHA3000V Hot Air Station. During manufacturing, the strictest quality requirements are applied; these assure the correct function of the device and make it possible to obtain optimal soldering results. Warning! Prior to placing the device in operation, please carefully read these operating instructions and the safety instructions enclosed. If the safety instructions are not observed, there is a risk of injury.
Technical data Dimensions (W x L x H) Mains/line voltage Power input Air volume Temperature range Accuracy Vacuum Compressed air connection Main fusing Protection class : 240 (9.44) X 270 (10.63) X 101 (3,97) mm (inches) : 230 V (120 V) AC : 475 W : 5 – 50 l/min. : 50°C – 550°C : + - 30°C (+ - 54°F) : 0.6 bar : 400 - 600 kPa : 230 V / T3,15 A (120 V / T6,3 A) : 1 (control unit and handpiece hard grounded) 2.
Selection of parameters by pressing button: • TEMP (7) : Nozzle temperature in °C/°F (See Switching Temperature Conversation page 12) • AIR (6) : Air flow rate in l/min • TIME/ PREHEAT (5) : Switch ON-OFF the nozzle preheating (standby) at 200°C (392°F) with 5 l/min airflow. After selection, the setting can be changed using the UP (2) or DOWN (3) Control Keys. Keeping the Control Key depressed, rapidly changes the values.
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.

2.4 Starting program The soldering process and thus the 3-step temperature-time profile is started: Directly on the Control Panel: START/STOP (10) Control Key, LED (9) illuminates.
PROGRAM 1 E X I T L O A D UP PRESS AT THE SAME TIME S A V E DOWN The program memories 1 - 10 can be selected using the UP/DOWN Control Keys (2)/(3). The preferred program can be selected by pressing the LOAD Control Key (6). The indication on the display changes to the automatic mode and displays the selected parameters. If a temperature-profile has been prepared, it can be saved in the selected program memory by pressing the SAVE Control Key (5).
temperatures (stage 1-3) have been reached. The times determined in this manner are shown after the soldering or desoldering process in the display (1) and can be saved. 3.3 External sensor with control function "CONTROL MODE" The temperature of the external sensor is controlled in this operating mode. The external sensor records the actual value (control variable) for the temperature control.
Use of nitrogen The use of nitrogen N2 reduces oxidation and the flux is active for a longer period. Nitrogen is available in steel cylinders at regular trade outlets. The cylinder must be equipped with a pressure reducer 0 – 10 bar. Caution!: Ensure adequate room ventilation when using nitrogen. 8.
