Intelligent Sensor Start: The soldering tip automatically recognizes the silicone cleaning port and triggers the motor to run, eliminating the need for manual switching. After insertion, gently shake left and right for 2-3 seconds to thoroughly remove residual solder. Three-Speed ​​Adjustment: Equipped with a three-speed switch, the rotation speed can be freely adjusted according to cleaning needs. The built-in high-density fine copper wire brush, using a dual-axis rotating design, quickly removes solder residue from the soldering tip, keeping it clean and like new. Rugged and Durable: The shell is made of ABS material, lightweight and sturdy; the cleaning port is protected with high-temperature resistant soft silicone for easy replacement, balancing durability and portability. Expandable and Low-Maintenance: The main controller has a reserved battery charging circuit for easy future battery installation. Gear meshing noise during cleaning is normal. The opening is compatible with most soldering tip types, making it a professional cleaning tool that is also easy to upgrade and maintain.
