ER70S-2 TIG Welding Rod for Carbon Steel Fabrication and Repair 

Clean weld deposits and consistent arc performance for TIG welding

The ER70S-2 TIG welding rod from PGN Bearings is designed for applications requiring smooth weld appearance, reliable arc stability, and consistent mechanical performance when welding carbon steel and low-alloy materials.

Its triple-deoxidized composition contains titanium, aluminum, and zirconium, helping reduce weld contamination and porosity while improving weld quality across a variety of fabrication and repair environments. This makes ER70S-2 a preferred filler metal for projects requiring cleaner weld deposits and dependable fusion characteristics.

The rod is widely used in industrial maintenance, structural fabrication, pipe welding, automotive work, and general metalworking applications where weld quality and appearance are critical.
