Hobart ER309/309L TIG Rod Purpose
This Hobart TIG welding rod is classified AWS ER309/309L for joining stainless steel to carbon steel, low-alloy steel, or stainless steel. It suits fabricators and repair shops needing a 10 lb package of 36 in rods for dissimilar-metal GTAW work.
Thermal Performance and Power
The rod operates on DCEN current and delivers an as-welded tensile strength of 85 ksi with a yield strength of 58 ksi. These mechanical values reflect the deposited weld metal properties under standard TIG process conditions.
Build Quality and Daily Handling
Each rod measures 0.0938 in diameter and 36 in length, supplied in a 10 lb container for extended production runs. The ER309/309L composition targets 309S base material grades, and the package carries California Proposition 65 warnings for cancer and reproductive harm.

Questions about this item
How do I set up the 3/32 inch ER309/309L rod for a TIG weld on stainless to carbon steel?
Use DCEN polarity as specified; match the 0.0938 inch diameter rod to the joint gap and feed it into the weld pool while shielding with argon.
What shelf-life or storage steps does the 10 lb pack of 36 inch rods require?
Store the rods in a dry, sealed container to prevent moisture absorption; no flux coating means they do not require re-baking before use.
At what stress level does the weld metal yield during prolonged loading?
The as-welded yield strength is 58 ksi, so sustained loads above this value will cause permanent deformation in the joint.
