Weller WSW SnPb Solder Wire 1.0 mm | Sn60Pb40, Flux 2.2%, 100 g

The Weller WSW SnPb solder wire is engineered for both hand and robotic soldering tasks, bringing a balanced mix of performance, reliability, and cost efficiency. With a 1.0 mm diameter and a 100 g reel, this wire uses Sn60Pb40 alloy and a 2.2% flux core to support steady wetting and predictable results across a range of substrates.

In practice, the wire is designed to promote smooth flow and consistent coverage, helping operators achieve clean, reliable joints with fewer interruptions. The 100% continuous flux core reduces the likelihood of dry joints and minimizes the need for rework, while the pure first-metal melting behavior supports stable processing under varied temperatures and speeds.

Enhanced performance for every joint

• Guaranteed 100% continuous flux core for stable wetting and reliable flow.
• Patented flow + heat performance with Sn60Pb40 alloy for predictable joints.
• Reduced splash feature to improve user safety and keep the workspace cleaner.
• Durable joints that resist cracking, even on challenging surfaces.

Practical benefits in real-world use

• Productivity gains come from lower tip consumption and faster cycle times, supporting efficient workflows.
• Lower total cost of ownership by reducing labor time and rework while maintaining quality.
• Versatile for both manual soldering and automated/robotic assembly lines, expanding deployment options.
