S520818-I26 - Hobart FabCO 309LT 1/16" Flux-Cored Stainless Wire, 33lb Spool

The Go-To Wire for Stainless-to-Steel Jobs

When you're tasked with welding a stainless steel bracket to a mild steel frame, or repairing a tank where the base materials don't match, you need a wire that handles the chemistry for you. The Hobart 309/309L 1/16" Flux-Cored Wire is built exactly for that. It runs with a smooth, buttery arc that makes laying down professional-looking beads feel almost effortless compared to fighting with stick electrodes or finicky solid wires on dirty material.

One of the biggest headaches with flux-cored stainless is the slag. Hobart has formulated this wire so the slag often curls up and peels off on its own as it cools, or comes off with a light tap of your chipping hammer. This saves you serious time on cleanup and grinding. Because it's a 1/16" wire, it packs a punch—you can lay down a lot of metal fast, which is perfect for heavy structural repairs or thick-walled piping in pulp and paper mills.

This spool is designed to run on DCEP and works great with straight CO2, which keeps your gas costs down, though it runs even smoother on a 75/25 mix. Whether you are working in the flat position laying down long fillet welds or handling multi-pass joints, this wire gives you the confidence that the weld won't crack and will hold up to the service conditions. It's a workhorse wire for the real-world welder.
