ER70S-6 1/16" TIG Filler Rod for Precision Mild Steel Welding

Designed for detailed fabrication and superior weld control

Some TIG welding projects prioritize precision over deposition rate. When working with smaller components, custom fabrication, thin-wall assemblies, or visually critical welds, filler metal control becomes one of the most important factors in achieving professional results.

The PGN Bearings ER70S-6 1/16" TIG filler rod is engineered for applications where accuracy and weld appearance matter. Its smaller profile allows gradual filler addition and improved puddle control, helping welders produce clean and consistent welds on carbon steel and low-alloy steel projects.

ER70S-6 remains one of the most widely used TIG filler metals because of its enhanced manganese and silicon content, which helps support cleaner welds and improved weld quality across a broad range of fabrication environments.
