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 workbench. 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.

First metal melting

First melting of metals (no recycled material) ensures consistent high quality and lowest contamination in the alloy.

Rosin

Homogeneous distribution of the activators within the resin ensures a uniform soldering result and the long-term reliability of the flux residues.

Alloy

Optimized micro-alloyed solder wire alloy to minimize oxidation of the soldering tip. More efficient, precise soldering and consistent high-quality solder joints while extending tip life and reducing costs.

100% Flux Core

Weller WSW Solder Wires have a 100% continuous flux core without any kind of air inclusions. The soldering process is not interrupted, and the solder joint reaches a different another level of quality and long-term stability.
