OVERVIEW

Smooth Running 308LSi Stainless Wire for Professional Fabricators

If you are welding stainless steel and want that "stack of dimes" look with less hassle, the Exocor ER308LSi .035" MIG wire is your go-to solution. The secret ingredient here is the extra silicon. While standard 308L is good, 308LSi is better for fluidity. That extra silicon helps the puddle wet out smoothly to the edges, reducing that sluggish feeling you sometimes get with stainless. The result? Flatter beads, less undercut, and significantly less time spent grinding or polishing your welds afterwards.

This 33lb spool is built for the long haul, perfect for shop production where you don't want to be swapping out small spools every few hours. The wire feeds clean and consistent, so you aren't fighting birdnests or burn-backs at the tip. It runs beautifully on DCEP polarity and pairs perfectly with your standard stainless gas mixes. Whether you are fabricating food service equipment, architectural features, or custom automotive exhaust systems using 304 stainless, this wire gives you the control you need.

The low carbon content protects your work from corrosion down the line, ensuring your welds hold up as well as the base metal. At .035", it's the perfect middle-ground size—heavy enough to lay down material quickly on thicker plate, but controllable enough for lighter gauge tubing when dialed in correctly. Upgrade your stainless game with a wire that works as hard as you do.

FAQ

The 'Si' stands for Silicon. 308LSi has a higher silicon content than standard 308L. This improves the fluidity of the weld puddle, allowing for better wetting at the toes of the weld and a flatter bead profile.

For MIG welding stainless steel, a mix of 98% Argon and 2% Oxygen, or a Tri-Mix (Helium/Argon/CO2) is typically recommended. Avoid 100% CO2 or 75/25 Argon/CO2 as they can compromise the corrosion resistance.

It is not recommended. You should use 316L wire for 316 base metals to match the Molybdenum content and ensure corrosion resistance. 308LSi is designed for 304/304L grades.

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

No, this is a solid wire. It requires an external shielding gas cylinder to protect the weld pool.

This is a 33lb (15kg) spool, which typically requires a full-size industrial wire feeder or a welder capable of holding 12-inch diameter spools. It will not fit small hobby welders that only take 2lb or 10lb spools without an adapter.

The 'L' stands for Low Carbon. This means the carbon content is restricted to a maximum of 0.03%, which helps prevent carbide precipitation and maintains corrosion resistance.

Yes, it is highly recommended to use a Teflon or plastic liner when feeding stainless steel wire to prevent contamination from steel liners and to ensure smooth feeding.
