OVERVIEW

Experience Smoother Welds with Hobart 308L Hi-Sil

If you have ever struggled with stainless steel weld puddles that feel sluggish or beads that pile up high in the center, the Hobart 308L Hi-Sil (ER308LSi) is the solution you have been looking for. This .035-inch MIG wire is engineered for welders who demand both performance and aesthetics. The "Hi-Sil" stands for High Silicon, and while that sounds like just another spec, on the shop floor, it translates to "smooth like butter." The extra silicon helps the molten metal flow out to the edges of the weld joint much better than standard 308L wire.

Why does this matter to you? First, it makes achieving that perfect "dime-stack" look much easier, even if you are moving fast. Second, because the bead lays flatter and ties into the sides more smoothly, you spend significantly less time grinding and polishing after the hood comes up. For industries like food and beverage or pharmaceutical tank fabrication, where every crevice must be eliminated to prevent bacterial growth, this wire is a game-changer. It creates smooth transitions that are easy to sanitize and look professional right out of the gun.

This 30lb spool is designed for serious fabrication work, fitting standard industrial wire feeders. Whether you are welding thin gauge stainless sheet for kitchen equipment or heavier structural components for a petrochemical plant, this wire gives you the control you need. It runs on DCEP polarity and works beautifully with Argon blends. The low carbon content also means you don't have to worry about ruining the corrosion resistance of the stainless steel you are working so hard to fabricate. Upgrade your stainless projects with a wire that works as hard as you do.

Ideal Applications:

  • Restaurant and commercial kitchen equipment
  • Brewery and dairy tanks
  • Custom automotive exhaust systems
  • Architectural stainless steel features
  • General maintenance and repair in corrosive environments

FAQ

The main difference is the silicon content. ER308LSi has higher silicon (0.65-1.00%), which improves the fluidity of the weld puddle, allowing for better wetting at the toes of the weld and a flatter bead profile compared to standard ER308L.

For MIG welding with ER308LSi, a mixture of 98% Argon and 2% Oxygen or 98% Argon and 2% CO2 is commonly used to ensure arc stability and good bead appearance. Tri-mix gases (Helium/Argon/CO2) can also be used for short-circuit transfer.

No, ER308LSi is designed for welding 300-series stainless steels (like 304) to themselves. To weld mild steel to stainless steel, you should use an ER309L or ER309LSi wire.

This wire is designed to run on Direct Current Electrode Positive (DCEP), also known as Reverse Polarity.

Yes, the ER308LSi grade is widely used in the food and beverage industry because it provides excellent corrosion resistance and smooth welds that minimize crevices where bacteria can grow.

It is primarily used for welding AISI types 304, 304L, 308, and 308L stainless steels.

This product comes on a 30 lb (approximately 13.6 kg) spool.

No, the 'L' stands for Low Carbon. This does not significantly reduce strength but greatly increases resistance to intergranular corrosion, which is critical for the longevity of stainless steel welds.
