100996 - Central Wire ER308LSi Stainless MIG Wire - 0.030 Inch - 2 lb Spool

Smoother Stainless Welds with 308LSi

If you have ever struggled with stainless steel MIG wire that feels sluggish or piles up in a ropey bead, the Central Wire ER308LSi is the solution you need. This 2-pound spool of 0.030" wire is formulated with extra silicon, which might sound like just another spec, but in the shop, it makes a world of difference. That extra silicon helps the puddle flow out—or "wet out"—much better than standard 308L wire. This means your puddle moves where you want it to, tying into the edges smoothly without creating that tall, convex crown that requires hours of grinding later.

This wire is designed for welding the most common stainless grades, like 304 and 304L. Because it is a 0.030" diameter, it is versatile enough for thin sheet metal work on exhaust systems or kitchen equipment, but can still handle slightly thicker brackets and frames. The 2lb spool size is perfect for spool guns or smaller 110V/220V MIG machines that don't take the large 33lb industrial spools. It’s the perfect size for small shops, hobbyists, or mobile repair trucks where you need stainless capability without hauling heavy inventory.

When running this wire, you'll notice a stable arc and very little spatter if your settings are dialed in. For the best results on thin material, use a Tri-Mix gas (Helium/Argon/CO2), but for general work, an Argon/CO2 mix (like C2 or C25, though C2 is better for stainless corrosion resistance) can work in a pinch for short circuit welding. The low carbon content also gives you peace of mind that your welds won't rust out from the inside later. Upgrade your stainless game with a wire that actually wants to work with you.
