Hobart Fabshield 21B 5/64" Flux-Cored Wire (33lb Spool)

The Hobart Fabshield 21B is a premium self-shielded flux-cored wire designed for general purpose fabrication and structural work. This 5/64-inch diameter wire comes in a 33lb spool, making it an economical choice for medium to heavy-duty industrial projects. As an E71T-11 classified wire, it is engineered to perform without the need for external shielding gas, significantly simplifying equipment requirements for field operations and outdoor job sites where wind can disrupt gas coverage.

Technical Performance and Versatility

Fabshield 21B is renowned for its operator appeal and versatility. It supports both single and multiple pass applications across all welding positions, including flat, horizontal, vertical, and overhead. This flexibility allows welders to tackle complex assemblies without changing consumables. The wire operates on DCEN (Direct Current Electrode Negative) polarity, providing a smooth arc that is forgiving on base materials that may not be perfectly clean. It is particularly effective on mild steels and is formulated to handle galvanized or coated steels with minimal porosity issues.

Industrial Applications

This wire is a staple in industries ranging from agriculture to construction. Its robust formulation ensures sound welds even in the presence of light rust or mill scale, reducing pre-weld preparation time. The 5/64" diameter offers a higher deposition rate compared to smaller wires, increasing productivity on thicker sections of steel. Post-weld cleanup is efficient thanks to its light slag system, which is easily removed to reveal a clean bead profile. Whether used for repairing heavy farm machinery, fabricating structural beams, or general maintenance, the Hobart Fabshield 21B delivers consistent, high-quality results.
