ELSOLD cored solder wires have been used successfully in electronics for decades, and allow solder and flux to be applied to soldering joints simultaneously. Despite the development of solder pastes which serve the same purpose, cored solder wires have been able to hold their own, and are still the preferred solution for applications such as manualrepair soldering or automatic soldering (robot soldering). ELSOLD cored solder wires are available in a wide range of different versions, offering unparalleled variety. What is most innovative about these products, aside from the purity of the base metal, is the constant adaptation of flux compounds to production parameters and processes. This means that rosins and activators must be adapted to higher or modified processing temperatures.The choice of suitable flux components and strictly controlled production conditions allow ELSOLD to manufacture top quality cored solder wires.
