2. Important Safety Warnings
For your own safety, please read these instructions carefully and follow them to prevent accidents due to improper use.
- Burns Hazard: Do not touch the metal part of the soldering iron tip or the heating core to avoid severe burns. Allow the tip to cool down completely before handling or replacing.
- Fire Hazard: Do not use the soldering iron near flammable materials.
- Children Safety: Keep the soldering iron and all its components out of reach of children to prevent accidents.
- Modifications: Do not modify the soldering iron or replace accessories with non-original parts. Unauthorized modifications can lead to malfunction and safety risks.
- Power Adapter: Ensure your power adapter supports PD3.0, PD3.1 (5V, 9V, 12V, 15V), QC (5V, 9V, 12V), Samsung AFC (5V, 9V), or FCP (5V, 9V, 12V) fast charging protocols. Using a non-fast charging adapter may result in malfunction.
- Battery: This product is not battery-powered and requires a constant power supply via its Type-C interface for operation.

4. Product Overview
The BK210 PRO features a compact design with an OLED display and intuitive controls. Its C210 integrated heating core ensures rapid heat-up and stable temperature control.



5. Setup
- Insert Heating Core: Carefully insert the C210 integrated heating core into the soldering iron handle. Ensure it is securely seated.
- Connect Power: Connect the Type-C charging cable to the soldering iron and then to a compatible fast-charging power adapter (supporting PD/QC/AFC/FCP protocols). The OLED screen will display "waiting for fast charging". Once the protocol is recognized, it will enter the heating state.
- Initial Power On: The screen will show the set temperature, actual temperature, and real-time power. The soldering iron will begin heating to the set temperature.
6. Operating Instructions
6.1. Power On/Off
- Power On: Connect the soldering iron to a fast-charging power source. It will automatically power on and begin heating.
- Power Off: Long press the power button. The screen will display "off", and the soldering iron will stop heating and enter standby mode.
6.2. Temperature Adjustment
- While the device is on, use the "+" button to increase temperature and the "-" button to decrease temperature.
- Each short press changes the temperature by one degree.
- Long press the "+" or "-" button for continuous temperature adjustment. Release the button once the desired temperature is reached. The motherboard will automatically save the setting.
- The temperature adjustment range is 180-480°C (356-896°F).
6.3. °C/°F Switching
- When the device is powered on, short press the power button to cycle through settings.
- When the screen displays the current temperature unit, use the "<" or ">" keys to switch between Celsius (°C) and Fahrenheit (°F).
6.4. Temperature Calibration
- In the power-on state, short press the power button to navigate to the temperature calibration setting.
- Use the "<" or ">" keys to adjust the calibration value. The calibration range is -99°C to +99°C.
- After calibration, the device automatically saves the data and exits the setting after 5 seconds.
6.5. Sleep Setting
- In the power-on state, short press the power button to navigate to the sleep time setting.
- Use the "<" or ">" keys to set the sleep time between 10-99 seconds.
- If the soldering iron remains stationary for the set duration, it will enter sleep mode, displaying "sleep" on the screen and stopping heating. This feature can be disabled if not needed.
6.6. Language Settings
- When the device is powered on, short press the power button to navigate to the language setting.
- Use the "<" or ">" keys to switch between Chinese and English.
7. Maintenance
- Tip Cleaning: Regularly clean the soldering tip using the provided wet sponge or brass wool to remove excess solder and oxidation. A clean tip ensures efficient heat transfer and better solder joints.
- Tip Tinning: After cleaning and before storage, tin the tip with a small amount of solder to prevent oxidation and prolong its lifespan.
- Heating Core Replacement: The C210 integrated heating core is replaceable. Always ensure the soldering iron has cooled down completely before attempting to replace the heating core to avoid burns.
- Storage: Store the soldering iron in a dry, safe place, preferably with the protective cap on, when not in use.
8. Troubleshooting
- Soldering Iron Not Heating: Ensure the Type-C cable is securely connected and the power adapter supports the required fast-charging protocols (PD/QC/AFC/FCP). A non-fast charging adapter will cause malfunction.
- Inaccurate Temperature Reading: Perform a temperature calibration as described in section 6.4.
- Soldering Iron Fails: If the soldering iron malfunctions or fails, it should be returned to the factory for inspection and repair. Do not attempt to repair it yourself unless you are a qualified technician.

10. User Tips
- Proper Tip Care: Always keep your soldering tip clean and tinned. This not only improves soldering quality but also significantly extends the life of your tip. Use the included wet sponge or a brass wire cleaner regularly.
- Experiment with Sleep Time: Adjust the automatic sleep time (10-99 seconds) to suit your workflow. A shorter sleep time saves energy and prolongs tip life if you frequently pause, while a longer time might be better for continuous work.
- Power Source Compatibility: Ensure your power bank or wall adapter explicitly supports one of the listed fast-charging protocols (PD, QC, AFC, FCP) to get the full 40W performance and rapid heating.
