This FOC automatic solder wire rewind reel is designed to meet the evolving needs of soldering stations. As soldering station technology advances, traditional soldering reels no longer meet the demands for precision, flexibility, and convenience in modern soldering tasks. Therefore, we developed this intelligent rewind solder reel. Key features include an auto-shutdown function, adjustable current and speed parameters, and a standardized, stable wire feed stroke. The rewind arc can be adjusted via a button to meet personalized needs. Additionally, the product uses an ultra-low power consumption design, requiring no external power supply, making it portable and easy to carry. It also displays real-time battery status, ensuring you are always aware of the remaining battery life, making it suitable for a wide range of soldering environments and applications. This solder reel not only enhances work efficiency but also integrates intelligent operation and convenience, making it the ideal companion for modern soldering tasks.
