Hobart Fabshield 21B .035 Flux-Cored Welding Wire - 10lb Spool

The Hobart Fabshield 21B is a premium self-shielded flux-cored welding wire designed for general purpose fabrication and repair. Identified by the SKU S222108-022, this 10-pound spool of .035-inch wire meets AWS E71T-11 classifications, making it a versatile choice for welders who require mobility and efficiency without the hassle of external shielding gas cylinders. It is specifically engineered to weld mild steel and is particularly effective on galvanized or coated steels where other wires may struggle with porosity.

One of the primary benefits of the Fabshield 21B is its ability to perform in all welding positions—flat, horizontal, vertical, and overhead—making it indispensable for field repairs and maintenance work. Because it generates its own shielding vapor from the flux core, it is an excellent solution for outdoor welding where wind conditions would typically disperse the shielding gas of a standard MIG setup. This wire runs on DC Straight Polarity (DCEN), which directs heat into the wire rather than the base metal, significantly reducing the risk of burn-through on thin-gauge materials.

Josef Gas recommends this wire for light structural fabrication, agricultural equipment repairs, and general maintenance. The 10lb spool size offers a substantial amount of material for ongoing projects while remaining manageable for portable wire feeders. Whether you are working in the shop or out in the field, the Hobart Fabshield 21B delivers consistent arc stability, good bead appearance, and easy slag removal, ensuring high-quality results with minimal post-weld cleanup.
