Powerweld er70s-6 mig welding wire. Aws a5.18 copper coated .045" diameter x 44lb spool. Powerweld er70s-6 wire contains high levels of manganese and silicon for stronger deoxidizing power where stringent cleaning procedures are not possible. This wire has been designed to provide x-ray quality porosity-free welds and the highest tensile strength (as welded) of the plain carbon steel wires. The high silicon content increases the fluidity of the weld pool, creating a smoother bead appearance and resulting in minimal post-weld grinding. Er70s-6 is excellent where poor fit-ups or rusty and oily plates may be used.
