OJ309L00000035F000 - Kobelco DW-309L .035 Flux Core Stainless Wire 28lb Spool

Smooth Running 309L Flux Core for Easy Cleanup

If you are welding stainless steel to mild steel, the Kobelco DW-309L .035" Flux Cored Wire is the operator's choice for a hassle-free experience. We know that flux-cored stainless can sometimes be messy, but Kobelco's Premiarc series is famous for its easy slag removal. In most cases, the slag lifts right off by itself as the weld cools, or requires just a light tap, saving you hours of grinding and chipping time. The bead profile comes out bright, smooth, and shiny, often requiring little to no post-weld finishing.

This wire runs beautifully on both straight CO2 and Argon/CO2 mixes. If you want deep penetration and lower cost, run it on CO2. If you want that classic smooth spray-like transfer with even less smoke, switch to the 75/25 mix. The arc is soft and stable, with virtually no spatter sticking to the base metal, which keeps your workpiece clean and professional-looking. It is designed for flat and horizontal fillets, making it perfect for structural joints, tank bottoms, and heavy equipment repairs.

The 28lb spool size is a great balance between economy and handling, fitting most industrial wire feeders. The .035" diameter gives you the control you need for medium-gauge materials while still packing enough punch for heavier plate when you crank up the wire feed speed. Whether you are doing underlayment for cladding or just joining a stainless bracket to a steel frame, this wire gives you the confidence that the weld will hold and look great.
