- Place the Station: Position the main unit on a stable, heat-resistant, and level surface in a well-ventilated area.
- Attach Handle Stand and Nozzle Bracket: Securely attach the handle stand and fan nozzle bracket to the side of the main unit as shown in Figure 1.
- Connect Hot Air Gun Handle: Plug the hot air gun handle cable into the handle socket on the front panel of the main unit. Ensure a firm connection.
- Select and Install Nozzle: Choose the appropriate nozzle for your task (cyclone or straight, various sizes) and securely attach it to the hot air gun. Place unused nozzles in the fan nozzle bracket.
- Connect Power: Plug the power cable into the power inlet on the back of the unit, then connect it to a suitable 110V or 220V AC power outlet.
- Initial Power On: Flip the power switch to the 'ON' position. The LED display will illuminate.
7. Operating Instructions
7.1 Power On/Off
Flip the main power switch located on the front panel to turn the unit ON or OFF.
7.2 Adjusting Temperature
- Press the 'TEMP' button. The temperature value on the LED display will flash.
- Use the up (▲) and down (▼) arrow buttons to adjust the desired temperature.
- The unit will quickly reach and stabilize at the set temperature.
7.3 Adjusting Airflow
- Rotate the 'AIR' adjustment knob clockwise to increase airflow or counter-clockwise to decrease it.
- The airflow level will be displayed on the LED screen.
7.4 Using Memory Channels (CH1, CH2, CH3)
The station features three memory channels to store frequently used temperature and airflow settings:
- To Save: Set your desired temperature and airflow. Press and hold one of the CH1, CH2, or CH3 buttons until the display indicates the settings are saved.
- To Recall: Briefly press the desired CH1, CH2, or CH3 button. The station will automatically adjust to the stored settings.
7.5 Straight Air / Spiral Air Selection
Use the 'Straight Air/Spiral Air' buttons to switch between different airflow patterns based on your application needs. Spiral air is generally preferred for even heating and component safety.
7.6 Handle Induction Switch
The hot air gun handle is equipped with an induction switch. When you pick up the handle, the system quickly enters working mode. When you place the handle back into its stand, the system automatically enters standby mode, reducing power consumption and prolonging the life of the heating element.
7.7 Celsius and Fahrenheit Conversion
The unit supports conversion between Celsius and Fahrenheit temperature units. Refer to the full manual for specific button combinations to toggle this setting.
7.8 Temperature Calibration Function
If the heating element is replaced or if you suspect temperature inaccuracies, the unit can be recalibrated. This machine uses a digital temperature calibration method where corrections can be made via incremental key input. Refer to the full manual for detailed calibration steps.
8. Maintenance
- Cleaning: Regularly clean the hot air gun nozzle and the station's exterior with a soft, dry cloth. Ensure the unit is unplugged and cooled down before cleaning.
- Nozzle Care: Keep nozzles free from solder residue and debris to ensure optimal airflow and performance.
- Heating Element: The unit features an automatic air cooling function to prolong the life of the heating element. If the heating element needs replacement, ensure proper temperature recalibration afterwards.
- Storage: When not in use for extended periods, store the soldering station in a dry, dust-free environment.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power cable disconnected, faulty outlet, power switch off | Check power connections, try a different outlet, ensure power switch is ON |
| No heat from gun | Handle not properly connected, faulty heating element, unit in standby | Ensure handle is fully seated, pick up handle from stand, contact support if heating element is suspected faulty |
| No airflow | Airflow knob set to minimum, fan malfunction | Adjust airflow knob, contact support if fan is suspected faulty |
| Temperature unstable | Environmental factors, faulty sensor, need for calibration | Ensure stable environment, perform temperature calibration, contact support if issue persists |
