Hobart ER309L 1/16" TIG Rods - 10lb Tube

Hobart ER309L: The Solution for Dissimilar Metal Welding

When your fabrication job calls for joining stainless steel to mild steel, you need a filler metal you can trust to handle the transition without cracking or failing. The Hobart ER309/ER309L TIG Welding Wire is the go-to rod for professional welders facing dissimilar metal challenges. Whether you are welding mounting brackets to a stainless tank or performing maintenance repairs on food processing equipment, this 1/16-inch wire delivers smooth feeding, stable arc characteristics, and a clean, aesthetically pleasing bead.

One of the biggest frustrations in a busy shop is mixing up filler metals. Hobart solves this by stamping the classification directly onto each 36-inch rod. You never have to guess if you are holding a piece of 308, 309, or 316; the identification is right there in your hand. This attention to detail helps prevent costly rework and ensures you are always using the right spec for the job. The 10-pound tube is durable and resealable, keeping your consumables clean and free from atmospheric contaminants that could introduce porosity into your TIG welds.

This wire is formulated to flow wet and smooth, making it easier to achieve that "stack of dimes" look even when bridging different base materials. The low carbon content gives you peace of mind that your welds will resist corrosion over time, which is vital for client satisfaction in industries like brewing, food service, and chemical processing. Designed for use with 100% Argon, this Hobart wire offers the consistency and quality that the brand is known for. If you are welding 300-series stainless to carbon steel, keep a tube of S510811-I12 in your rod oven or storage rack—it is the versatile problem-solver every TIG welder needs.
