S222108-019 - Hobart Fabshield 21B .035" E71T-11 Self-Shielded Flux-Cored Wire 2lb Spool

Reliable Outdoor Welding with Hobart Fabshield 21B

For welders seeking a robust solution for outdoor projects and on-site repairs, the Hobart Fabshield 21B .035" Flux-Cored Welding Wire is the answer. This self-shielded wire (AWS E71T-11) is designed to operate without a shielding gas tank, making your welding setup significantly lighter and more portable. Whether you are up on a ladder, out in a pasture repairing fences, or working in a drafty garage, the Fabshield 21B ensures that wind won't compromise your weld quality. The 2lb spool (S222108-019) is perfectly sized for smaller, portable wire feed welders, allowing you to take high-performance welding capabilities directly to the job site.

Optimized for Thin Gauge and Galvanized Materials

Burn-through is a common headache when welding thin sheet metal, but the Fabshield 21B is engineered to help you avoid it. By utilizing DC Straight Polarity (DCEN), this wire directs more heat into the wire and less into the base metal, providing a softer arc that is ideal for thin gauge mild steel. Furthermore, it is an excellent choice for welding galvanized steel. The specialized flux formulation helps to combat the zinc coating, reducing the spatter and porosity often associated with galvanized materials. This makes it a go-to wire for ductwork, roofing, and automotive body repairs where coated steels are prevalent.

Cost-Effective and Versatile Performance

While solid MIG wire has its place for aesthetic, high-production shop welds, the cost and hassle of renting and transporting gas cylinders can be prohibitive for many applications. The Fabshield 21B offers a cost-saving alternative by eliminating the gas requirement entirely. It supports all-position welding—flat, horizontal, vertical, and overhead—giving you the freedom to weld in difficult angles without changing your setup. Although it may produce slightly more spatter than a gas-shielded solid wire, the trade-off is a highly versatile, "grab-and-go" welding solution that gets the job done efficiently.

Usage and Storage Tips

To get the best results from your Hobart Fabshield 21B, ensure your machine is set to DCEN (electrode negative). If your welder was previously set up for solid wire with gas (DCEP), you will need to swap the polarity leads inside the machine. Store the spool in a dry, low-humidity environment when not in use to prevent moisture absorption into the flux, which can affect performance. With proper storage and setup, this wire delivers consistent feeding and strong, durable welds for a wide range of general fabrication and maintenance tasks.
