When your project calls for joining stainless steel to mild steel, professional welders turn to the reliability of Hobart's ER309/ER309L TIG welding wire. This 10-pound tube of 1/8-inch rods is a shop essential for fabrication, maintenance, and repair tasks where dissimilar metals meet. Hobart has built a reputation for manufacturing consumables that run consistently, and this stainless wire is no exception. It feeds smoothly through the hand and creates a clean, controllable puddle that wets out perfectly, allowing you to lay down beads that look as good as they hold.
One of the biggest headaches in a busy welding shop is identifying loose filler metal. Hobart solves this by stamping every single 36-inch rod with the alloy type and lot number. You will never have to guess if you are holding a 308, 309, or 316 rod again. This feature alone saves time and prevents costly mistakes on critical parts. The 1/8-inch diameter is robust enough for filling larger joints and working on thicker base materials, providing the deposition rates you need to get the job done efficiently.
The "L" in ER309L stands for Low Carbon, which is great news for the durability of your welds. It helps prevent corrosion in the heat-affected zone, ensuring that your work stands up to the elements and harsh chemical environments found in food processing or petrochemical plants. Whether you are building custom brackets, repairing heavy machinery, or fabricating exhaust components, this wire gives you the versatility to weld 300-series stainless to carbon steel with confidence. Simply pair it with 100% Argon gas, clean your base metal thoroughly, and experience the superior performance of genuine Hobart filler metal.
