Hobart S222112-022 Fabshield 21B .045 Flux-Core Wire

When your welding projects take you outdoors or into hard-to-reach places, hauling a shielding gas cylinder is often not an option. The Hobart Fabshield 21B .045" Flux-Cored Wire is the solution for welders who need mobility without sacrificing weld quality. This 10-pound spool is perfectly sized for portable suitcase feeders and shop welders, providing enough material for substantial jobs while keeping your rig light enough to move. As an E71T-11 class wire, it generates its own shielding vapor from the flux core, ensuring your weld pool is protected even in windy conditions that would blow away argon/CO2 gas.

This wire is a favorite among farmers, maintenance crews, and hobbyists for its forgiving nature. It is exceptionally good at bridging gaps and welding over dirty or galvanized metals. If you are repairing fences, fixing agricultural equipment, or working on galvanized structural parts, Fabshield 21B is the wire you want in your machine. It runs on DCEN (straight polarity), which helps keep the heat manageable on thinner sheet metals, preventing you from blowing holes through your workpiece. While solid wire (ER70S-6) might offer a slightly prettier bead in a controlled shop environment, it cannot compete with the versatility and "go-anywhere" capability of Fabshield 21B.

The .045" diameter allows for higher deposition rates, helping you finish thicker repairs faster than smaller diameter wires. It produces a light slag that covers the weld bead, protecting it as it cools, which typically chips off easily with a hammer or wire brush. Whether you are welding flat, vertical, or overhead, this wire stays controllable and produces a sound, strong bond.
