ER70S-2 is a copper coated, triple deoxidized (Silicon, Manganese, Aluminum) mild steel wire, giving radiographic welds with minimum spatter and smooth flow, stable arc under proper conditions. Tensile strength will exceed base metal on single pass welds in low carbon steels.


  • XTR 70S-2 is recommended for high quality pipe welding for mild and medium tensile steels and is ideal for root passes on thick-walled material.
  • Also, excellent where poor fit-up, rust and oils may be present.
