Copper Coated

JACKSUN MIG 80SG

AWS/ASME: A5.28 ER80S-G

JACKSUN MIG 80SG is a copper-coated low-alloy solid wire designed for MIG/MAG and TIG welding applications.
Suitable for high-strength low alloy (HSLA) steels and quenched & tempered steels.
Provides good toughness at low temperatures, high strength, and crack resistance.
Contains Mn, Ni, Cr, Mo alloying elements for improved strength and toughness.
Typical applications include offshore structures, pressure vessels, pipelines, shipbuilding, and heavy equipment fabrication.Polarity: DCEP
