5. Setup
Before connecting the R118E handpiece, ensure your YIHUA 853D 3A USB Station is powered off and unplugged from the main power supply.
- Verify Compatibility: Confirm that your original hot air gun handle's model number is R118E. If unsure, contact YIHUA support for verification.
- Disconnect Old Handpiece (if applicable): Carefully unplug the existing hot air gun handpiece from the YIHUA 853D 3A USB Station.
- Connect New Handpiece: Align the multi-pin connector of the R118E replacement handpiece with the corresponding port on the YIHUA 853D 3A USB Station. Gently push until it is securely seated. Do not force the connection.
- Secure Connection: If your station's port has a locking mechanism (e.g., a screw collar), tighten it to prevent accidental disconnection during operation.
- Attach Nozzle: Select the appropriate hot air nozzle for your application and securely attach it to the end of the handpiece.
The station is now ready for power-up and operation with the new handpiece.
6. Operating Instructions
The operation of the hot air gun is controlled by the YIHUA 853D 3A USB Station. Refer to your station's manual for detailed instructions on setting temperature and airflow.
- Power On: Plug in and power on your YIHUA 853D 3A USB Station.
- Set Temperature: Adjust the desired temperature using the controls on the station. Start with lower temperatures and gradually increase as needed for your specific application.
- Set Airflow: Adjust the airflow rate on the station. Higher airflow is generally used for larger components or faster heating, while lower airflow is for delicate work.
- Preheating: Allow the hot air gun to reach the set temperature before beginning work. The station display will indicate when the temperature is stable.
- Operation: Hold the handpiece firmly and direct the hot air stream towards the component or area to be worked on. Maintain a safe distance to avoid overheating or damaging surrounding components.
- Cool Down: After use, place the hot air gun back into its stand. Most YIHUA stations feature an automatic cool-down function, which will continue to blow air until the temperature drops to a safe level before powering off the heating element.
- Power Off: Once the cool-down cycle is complete, power off the station.

- Nozzle Care: Ensure nozzles are clean and free from debris. Replace damaged or clogged nozzles to maintain proper airflow and heating efficiency.
- Air Vents: Keep the air vents on the handpiece clear of dust and obstructions to allow for proper cooling.
- Cable Inspection: Regularly inspect the power cable for any signs of damage, cuts, or fraying. If damage is found, discontinue use and replace the handpiece.
