The MATHESON ER70S-6 Carbon Steel MIG Welding Wire is a versatile solid welding wire designed for gas metal arc welding (GMAW/MIG) applications. Featuring a .035in wire diameter and a 33lb spool, this welding wire is an excellent choice for fabrication shops, trailer manufacturing, equipment repairs, automotive applications, and general steel construction projects.
ER70S-6 welding wire contains higher levels of manganese and silicon deoxidizers, helping produce consistent welds on mild and carbon steel, including surfaces with light mill scale or minor surface contaminants. The larger 33lb spool is ideal for frequent welding applications, helping reduce spool changes and improve productivity in busy fabrication environments.
