ED511012 - Lincoln Fleetweld 37+ E6013 4.0mm Welding Rods

Smooth Running, Easy Cleaning E6013 Rods

If you are looking for a welding rod that just works, the Lincoln Fleetweld 37+ is a legendary choice in the E6013 category. Known for its incredibly smooth arc and easy handling, this 4.0mm rod is perfect for those jobs where you need to get it done quickly and have it look good. Whether you are fixing farm equipment, building a trailer, or doing general repairs around the shop, the Fleetweld 37+ is forgiving enough for beginners but performs at a level that pros appreciate.

Why Welders Love It

The first thing you will notice is how easy it is to strike an arc. Even if you are using an older AC machine or a smaller welder that struggles with other rods, the Fleetweld 37+ lights up instantly. It runs with a quiet, steady hiss and produces very little spatter, keeping your workpiece clean. When you are done with a pass, the slag often curls up and peels off by itself, or comes off with a light tap of your chipping hammer. No more fighting with stubborn slag inclusions or spending half your day grinding.

Great for Tricky Fit-Ups

We all know that real-world welding doesn't always involve perfectly cut, clean steel. This rod is excellent for bridging gaps and handling poor fit-up. Because it has lighter penetration than a 6010 or 6011, you are less likely to blow holes through your material, making it a safe bet for sheet metal or worn-out parts. You can drag it, weave it, or whip it—it adapts to your style. It runs beautifully in all positions, so if you have to weld a vertical bracket or an overhead seam, you don't need to switch rods.

Ready for Any Machine

You don't need a high-end industrial power source to run these. They are designed to work with AC, DC+, or DC- polarity. This versatility means you can grab a box of Fleetweld 37+ and know it will run on whatever machine is available at the job site. For the 4.0mm size, just dial your machine to around 130-140 amps to start, and adjust from there for a buttery smooth bead that makes you look like a master welder.
