Hobart Fabco 71 .052 Flux-Cored Wire 33lb Spool

Premium Performance with Hobart Fabco 71 Flux-Cored Wire

Hobart Fabco 71 is a staple in the welding industry, renowned for its exceptional operator appeal and mechanical integrity. This 0.052-inch diameter wire is an all-position, gas-shielded flux-cored electrode designed for welding mild and medium carbon steels. The 33lb spool is vacuum-packed to prevent moisture pickup, which is critical for maintaining low hydrogen levels and preventing weld defects such as porosity or hydrogen cracking. It is an ideal choice for welders seeking a balance between high deposition rates and ease of use.

One of the standout features of Fabco 71 is its forgiving arc. It provides a stable, smooth transfer with minimal spatter, which improves welder comfort and visibility. The fast-freezing slag shelf supports the weld puddle effectively in vertical-up and overhead positions, allowing for higher amperage settings and faster travel speeds compared to many other wires in its class. This translates to increased throughput and efficiency in production environments. The slag removal is exceptionally easy, often detaching in large pieces, which streamlines multi-pass welding operations.

Applications for the Fabco 71 are vast, ranging from structural steel erection and barge construction to the manufacturing of heavy earth-moving equipment. It delivers robust mechanical properties, including good impact toughness at lower temperatures, making it suitable for critical applications requiring AWS E71T-1 compliance. By optimizing the flux formulation, Hobart has created a wire that performs reliably under both 100% CO2 and mixed gas shielding, ensuring consistent penetration and fusion.
