S222106-015 - Hobart Fabshield 21B .030" Self-Shielded Flux-Cored Wire - 500lb Reel

Go-Anywhere, Weld-Anything Flux Core Wire

When you need a wire that just works, regardless of the conditions, Hobart Fabshield 21B is the legendary answer. This .030" self-shielded flux-cored wire is designed to get you welding without the hassle of dragging a gas bottle around. Whether you are fixing a gate in the wind, repairing farm equipment in the field, or fabricating in the shop, Fabshield 21B lays down a smooth, consistent bead with excellent penetration. This specific listing is for the massive 500lb reel, perfect for shops that burn through wire and want to stop swapping out small spools every few hours.

One of the biggest headaches in welding is dealing with dirty or galvanized metal. Fabshield 21B eats that up. It is formulated to weld right over galvanized coating and light rust without popping and sputtering like solid wire would. It runs on straight polarity (DCEN), which keeps the heat in the wire and helps prevent burn-through on thinner materials, while still being capable of handling plate up to 1/2" thick with multiple passes. The slag is easy to chip off, leaving you with a clean, professional-looking weld.

This wire is an "all-position" champ. Vertical up? Overhead? No problem. The puddle freezes fast enough to keep your weld where you put it, not on the floor. If your shop does a lot of general repairs, prefab work, or outdoor construction, loading up a bulk reel of Fabshield 21B ensures you are ready for anything that rolls through the door.
