Copper Coated

JACKSUN MIG 70S6

AWS/ASME: A5.18 ER70S-6

JACKSUN MIG 70S6 is a copper-coated solid wire suitable for MIG/MAG and TIG welding of carbon steels and low alloy steels.
High silicon and manganese content improves deoxidation.
Excellent for welding over light rust, scale, or oily surfaces.
Produces smooth bead appearance with low spatter.
Suitable for structural steel, pressure vessels, pipelines, and automotive fabrication.
