Copper coated mild steel MIG wire electrode S-6 is an excellent choice for welding on metals with a medium to high presence of surface contaminants such as rust or mill scale. It is a low carbon, high manganese and very high silicon wire that exhibits very good puddle fluidity, bead profile and spatter control relative to other leading brands of GMAW wire. To assure consistent chemical composition, Linde S-6 is evaluated for a number of different elements from raw materials to finished product. This thorough analysis ensures that Linde S-6 consistently complies to CWB, AWS and ASME requirements. Excellent spatter control and bead profile. Highly resistant to copper flaking, which can clog liners and contact tips. Copper coating provides superior arc-starting characteristics, for long contact tip life. Linde S-6 is designed to deliver trouble free feedability because of the proprietary drawing processes which ensure extremely tight tolerances on diameter.
