The Weller solder wire designed to enhance the quality of all hand and robotic soldering jobs, Weller WSW increases productivity while reducing operating costs. WSW solder wires optimize the performance of the soldering process by reducing tip consumption , ensuring a low total cost of ownership by decreasing labor time and resources. The patented Reduced Splash feature increases direct user safety and clean workbrench. With a guaranteed 100% continuous flux core, combined with pure first metal melting, WSW avoids costly rework and enables long-term, highly durable solder joints without cracking, even on difficult surfaces.
