Soldering Process

- Allow the iron to reach the desired temperature. The LED display will show the real-time temperature.
- Clean the soldering tip by wiping it on a damp sponge.
- Apply a small amount of solder to the tip (tinning) to improve heat transfer.
- Place the hot tip against the components to be soldered, heating both simultaneously.
- Apply solder to the heated joint, not directly to the iron tip. Allow the solder to flow smoothly.
- Remove the solder wire, then remove the iron. Allow the joint to cool naturally without disturbance.

The Soarfly C210 can be used in both cordless mode (powered by its internal battery) and corded mode (while connected to a USB-C power source). This allows for continuous operation when needed.
Smart Features

Image: Diagram showing the smart features of the Soarfly C210 soldering iron. It illustrates that the iron enters sleep mode after 40 seconds of idle time and automatically powers off after 10 minutes of inactivity, with a sleep mode indicator.
- Auto-Sleep: If the soldering iron is idle for 40 seconds, it will automatically enter sleep mode to conserve energy and prevent tip oxidation. The sleep mode indicator will activate. To wake it up, simply pick up the iron or press any button.
- Auto-Power Off: After 10 minutes of continuous inactivity (in sleep mode), the soldering iron will automatically power off completely for safety.
Charging
The Soarfly C210 soldering iron is equipped with a built-in rechargeable battery and charges via a USB-C port.
- Connect the provided USB-C cable to the soldering iron's charging port and to a compatible USB power source (e.g., wall adapter, power bank, computer USB port).
- The LED display will indicate the charging status and battery level.
- A full charge provides approximately 60 minutes of continuous use.
- The iron can be used while charging (corded mode).
Maintenance
- Tip Cleaning: Regularly clean the soldering tip using the damp sponges provided. This helps prevent oxidation and ensures efficient heat transfer.
- Tip Tinning: After cleaning and before storage, apply a small amount of fresh solder to the tip to prevent oxidation and prolong its lifespan.
- Storage: Store the soldering iron in a dry, cool place, away from direct sunlight and moisture. Ensure it is powered off and cooled down before storing.
- General Cleaning: Wipe the body of the soldering iron with a soft, dry cloth. Do not use abrasive cleaners or solvents.
