ER70S-6 3/32" TIG Filler Rod for Mild Steel Fabrication and Structural Welding

Built for clean welds and dependable performance on carbon steel

Real-world fabrication rarely happens on perfectly prepared metal. Fabricators often encounter light mill scale, minor oxidation, or surface contaminants that can affect weld quality and consistency.

The PGN Bearings ER70S-6 3/32" TIG filler rod is engineered to help address these challenges. Its formulation contains manganese and silicon deoxidizers that help improve weld quality and support consistent weld bead formation on carbon steel and low-alloy steel applications.

Widely used in fabrication shops, industrial maintenance, agricultural equipment manufacturing, and structural steel projects, ER70S-6 remains one of the most trusted TIG filler metals for everyday carbon steel welding.
