Hobart Fabshield 21B .030" Flux-Cored Wire Overview

The Hobart Fabshield 21B is a premium self-shielded flux-cored wire designed for general purpose fabrication and repair. Classified under AWS E71T-11, this wire is engineered to perform exceptionally well without the need for external shielding gas, making it a preferred choice for field applications where gas cylinders are impractical or where wind conditions would compromise gas coverage. The .030-inch diameter provided in this compact 2lb spool is ideal for portable welding machines and spool guns, offering high mobility for maintenance teams and on-site fabricators.

One of the standout characteristics of the Fabshield 21B is its ability to handle coated steels. It is specifically formulated to weld over galvanized surfaces and mild rust, reducing the need for extensive pre-weld cleaning and preparation. This makes it highly efficient for agricultural repairs, fencing, and structural maintenance where pristine metal surfaces are not always achievable. The wire produces a smooth arc with a spray-type transfer that ensures good fusion and bead appearance, even in out-of-position welds.

Operated on DCEN (Direct Current Electrode Negative) polarity, the Fabshield 21B delivers a soft arc that is easy to control. It is suitable for both single and multiple pass applications, providing versatility across different joint configurations and material thicknesses. The slag system is designed to be light and easy to remove, which streamlines the finishing process and increases overall productivity. Whether used for lap welds, butt welds, or fillets, this wire maintains consistent mechanical properties and structural integrity.
