S222112-022 - Hobart Fabshield 21B .045 Flux-Core Wire 10lb Spool

Hobart Fabshield 21B .045" Flux-Cored Welding Wire (10lb Spool)

The Hobart Fabshield 21B is a premium self-shielded flux-cored wire designed for general-purpose fabrication and repair on mild and galvanized steels. Classified as E71T-11 under AWS standards, this wire is engineered to perform without the need for external shielding gas, making it a highly efficient solution for workshops and field applications alike. The S222112-022 SKU provides a convenient 10-pound spool, ideal for medium-duty wire feeders and portable welding setups.

One of the standout technical characteristics of the Fabshield 21B is its operation on DC Straight Polarity (DCEN). This polarity setting significantly reduces penetration compared to DCEP, which is advantageous when welding thinner gauge materials as it minimizes the risk of burn-through. Despite this, the wire maintains excellent arc stability and deposition rates suitable for structural applications. The flux core contains specific scavengers and deoxidizers that allow it to handle light rust and mill scale, but it truly excels on galvanized steel, where it helps prevent the porosity issues common with solid wire welding.

This wire is an all-position consumable, meaning it can be used for flat, horizontal, vertical, and overhead welds with ease. It supports both single and multiple pass applications, offering versatility for complex joint configurations. The slag system is designed for quick freezing and easy removal, revealing a clean bead profile. For industrial environments where gas cylinders are logistical burdens or where drafts compromise gas coverage, the Fabshield 21B offers a reliable, high-strength alternative to traditional MIG welding.

Key Technical Benefits

• Gasless Operation: Eliminates the cost and handling of shielding gas bottles.
