L1 Solder Wire (Sn60 Pb40 / Flux Content 2.2%)
Designed to enhance the quality of all your soldering jobs, Weller WSW increases productivity, and optimizes your soldering performance. With a guaranteed 100% continuous flux core, combined with pure first metal melting, WSW enables long-term, highly durable solder joints.
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.
