The Hobart ER70S-2 is a premium carbon steel cut-length TIG rod designed for the Gas Tungsten Arc Welding (GTAW) process. Identified by the industry shorthand "702" or the AWS classification ER70S-2, this filler metal is engineered with a triple-deoxidized chemistry containing Zirconium, Titanium, and Aluminum. This specific alloy composition makes it the preferred choice for critical welding applications where base metal cleanliness cannot be guaranteed or where the highest weld integrity is required.
With a diameter of 1/8" and a standard length of 36", these rods are suitable for welding heavier wall thicknesses and structural components. The deoxidizers actively scavenge oxygen and impurities from the weld pool, significantly reducing the risk of porosity when welding over mill scale, light rust, or oil. This makes the Hobart ER70S-2 an essential inventory item for maintenance and repair operations (MRO), pipe welding, and pressure vessel fabrication.
Josef Gas supplies this product in convenient tube packaging, ensuring the rods remain straight and protected from atmospheric moisture until use. It meets AWS A5.18 specifications and is compatible with 100% Argon shielding gas for optimal arc stability and puddle control.
