OVERVIEW

The Industry Standard for Smooth MIG Welding

If you are looking for a MIG wire that just runs right every time, Lincoln's SuperArc L-56 is the legendary choice. This .045-inch solid wire is the go-to for welders who need to tackle dirty steel without fighting the puddle. Thanks to its high silicon and manganese content, it eats through rust, oil, and mill scale, leaving you with a clean, solid weld and very little porosity.

We know that constantly changing contact tips or dealing with bird-nesting is a hassle. That's why the L-56 features a superior copper coating that helps it glide through your liner and gun, keeping your arc stable and your tips lasting longer. Whether you are running short-circuit on thinner gauge steel or spraying on heavy plate, this wire handles it all with a smooth, fluid puddle that wets out perfectly at the toes.

This 44lb spool is perfect for shop setups, giving you plenty of runtime between changeovers. It produces a great-looking bead with minimal spatter, meaning less cleanup time with the grinder and more time burning wire. When you need a reliable ER70S-6 wire that makes you look good, trust the SuperArc L-56.
