Kester® 331 1lb roll wire solder, 0.031" diameter, core 66.

Alloy: Sn63Pb37

Kester® 331 Organic Flux is a water soluble formula for use in flux-cored wire. This cored solder version of the popular #2331 Neutral Organic Water Soluble Liquid Flux is more effective than rosin fluxes in soldering difficult metals. The same fast action and mild properties are exhibited with 331 Oranic Flux as with the liquid #2331. This flux is more heat stable than most organic fluxes, resulting in minimal smoke and odor. The residue can be completely removed with a simple water rinse.
