Item Details

  • Harris® TIG (GTAW) ER70S-6 3/32" Dia X 36" Carbon Steel TIG Welding Rod comes in a 10 lb box. This mild steel welding alloy contains more deoxidizers than ER70S-3. Thus, yields better wetting for a flatter bead shape and the capability of faster travel speeds. A general-purpose welding rod for fabrication of mild steel and used primarily for multiple pass on steels where rusty and dirty surfaces are not cleaned before welding. Conforms to AWS A5.18 ER70S-6 standards.
