Features: Rosin core design: The rosin core solder wire adopts a rosin core design, which facilitates the automatic wetting of the solder wire by rosin during welding, providing a smootherand more stable welding effect : The product is made of highpurity tin wire, which has good welding performanceand conductivity, ensuring firm and reliable welding connections. Easy to operate: The solder wire is easy to use and can quickly melt, making welding work more efficient and convenient. Rosinc ore content: The product contains a rosin core inside, which gradually melts during welding, helping the solder wire to better wet the welding surfaceand provide a more uniform and reliable welding effect. Uniform and delicate: The solder wire is finelyprocessed, with a uniform and delicate wire diameter, making it easy to control the flowof solder during welding and providing accurate welding results. Strong oxidation resistance: The product has undergone special treatmentand has strong oxidation resistance, reducing the oxidation rate of the solder wire and extending its service life.
