The BOSSWELD S6 ER70S-6 is a copper-coated TIG wire designed for welding mild steel, specifically carbon and carbon-manganese steels with tensile strength up to 510 MPa. This 1.6mm diameter wire comes in a convenient 1 kg handy pack, ideal for professional welders and fabricators working on structural steel projects.

This TIG wire meets the AWS A5.18 ER70S-6 specification and is suitable for a variety of applications including tanks, boilers, steel structural works, earthworks, and general construction. It is commonly used for root pass welding and to support welds where back pass welding is not feasible. The copper coating enhances weldability over mill scaled plates and provides excellent mechanical properties and toughness, even in low temperature conditions.

Key features of the BOSSWELD S6 ER70S-6 TIG wire include:

• Copper coated wire optimized for TIG welding and brazing
• Capable of welding over mill scaled steel plates
• Produces tough, durable weld metal with excellent mechanical strength

Typical applications include tube sections, construction and manufacturing tasks, general steel repairs on rusty or oily plates, sheet metal work, and steel structural components such as tanks and boilers.
