• Alloy Sn99.3Cu0.6Ni0.05, Flux content 3.5%
• Silver free alloy = cost-effective
• Guaranteed 100% continuous flux core
• Higher-strength due to nickel compared to other silver-free alloys
• Reduced Fe leaching to increase tip life time and reduce tip consumption by up to 70%
• Very fast wetting even on difficult surfaces, as dirty and oxidized materials

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.
