Description
Harris ER70S-6 Mild Steel MIG Welding Wire
Harris ER70S-6 MIG (GMAW) welding wire is a general-purpose mild-steel filler wire with higher silicon and manganese deoxidizer levels than ER70S-3. The added deoxidizers improve wetting, support a flatter bead profile, and allow faster travel speeds on many carbon-steel fabrication applications.
