Hampdon Industrial supplies Premium quality ER70S-4 Steel TIG filler rod. ER70S-4 is a great filler rod for low to medium presence of surface contaminants such as rust or mill scale. S4 wire has all of the advantages of S2, with slightly higher levels of manganese and silicon. It has higher “cleaning” levels, and produces a more fluid weld puddle and flatter bead profile. Our high purity fillers have sensational flow characteristics and produce exceptional welds that are free of cracks, Fusion defects and other problems which inferior wires are prone to. Each rod is individually stamped or laser engraved with its grade identification marking.
