4. Setup
- Unpack: Carefully remove all components from the packaging.
- Placement: Place the soldering station unit and the soldering iron holder on a stable, heat-resistant, and well-ventilated workbench.
- Connect Soldering Iron: Insert the soldering iron's airline jack into the corresponding port on the main unit. Ensure it is fully inserted for proper contact.
- Power Connection: Connect the power cord to the soldering station and then to a suitable power outlet (AC110V or AC220V, 50HZ/60HZ, depending on your model and region).
- Prepare Cleaning Sponge: Wet the cleaning sponge in the soldering iron holder with water. Squeeze out excess water so it is damp, not soaking wet.
5. Operating Instructions
5.1 Power On/Off
- Flip the Switch on the front panel to turn the unit ON or OFF.
- For KUAIQU-203D, the digital display will light up. For KUAIQU-203A, an indicator light will show the power status.
5.2 Temperature Adjustment
- KUAIQU-203A (Knob Control): Rotate the Temperature Knob to adjust the desired temperature. The temperature range is 200°C to 480°C (392°F to 896°F).
- KUAIQU-203D (Button Control): Use the Increase (right arrow) and Decrease (left arrow) buttons to adjust the temperature value. Press the OK (star) button to confirm and save the data. The temperature range is 90°C to 480°C (194°F to 896°F).
