A general purpose flux cored solder for use on most metals including steels, tinned sheets, galvanised, copper and brass. Solder procedure:  1. Thoroughly clean all areas to be joined, remove dirt and grease to ensure a perfect joint. 2. In the case of lap joints, allow 5 thou (0.1mm) gap between faces to allow metal to flow between joints. 3. Heat the job(do not overheat) and touch the wire to the job, following through with iron or torch, the alloy will begin to flow when the correct temperature is reached. 4. Keep melting the alloy off and allow it to flow into the joint until the joint is completed. 5. Remove any flux residue with water. 6. Grind or polish as required where a neat finish is needed.
