S222125-V14 - Hobart Fabshield 21B 5/64" Self-Shielded Flux-Cored Wire, 50lb Coil

Industrial-Grade Self-Shielded Flux-Cored Wire

The Hobart Fabshield 21B is a premium self-shielded flux-cored wire designed for general purpose fabrication where high deposition rates and all-position capabilities are required. Formulated to meet AWS E71T-11 specifications, this wire operates on DCEN (Direct Current Electrode Negative) polarity and does not require an external shielding gas, making it an optimal choice for field applications where wind or drafty conditions would compromise gas-shielded processes.

This 5/64-inch diameter wire is supplied in a 50 lb coil, suitable for industrial wire feeders. The Fabshield 21B chemistry provides a fast-freezing slag system, which supports the weld puddle effectively in vertical-up and overhead positions. It is engineered for both single and multi-pass welding on mild steel, offering versatility across various structural projects. The wire exhibits excellent bead geometry and mechanical properties, ensuring reliable joint integrity in thicknesses ranging from 1/8 inch up to 3/4 inch and beyond with proper technique.

Metallurgically, the Fabshield 21B is designed to handle moderate levels of mill scale and rust, reducing the need for extensive pre-weld cleaning. This characteristic, combined with its high deposition efficiency, significantly improves throughput in production environments. It is widely utilized in industries such as heavy equipment manufacturing, railcar repair, and general structural steel erection.
