S283319-K29 - Hobart TM-771 1/16" E71T-1 Flux-Cored Wire 33lb Spool

Hobart TM-771 1/16" Flux-Cored Welding Wire (S283319-K29)

The Hobart TM-771 is a high-performance gas-shielded flux-cored wire designed for critical structural and fabrication applications. Engineered to meet the rigorous AWS E71T-1 classification, this 1/16-inch diameter wire is formulated for use with 100% CO2 shielding gas, providing an economical yet high-quality solution for heavy-duty welding. The wire is supplied on a 33-pound vacuum-packed spool (VPSP), ensuring optimal protection against moisture absorption and contamination during storage and transit, which is crucial for maintaining its low-hydrogen characteristics.

One of the standout technical features of the TM-771 is its diffusible hydrogen content, which is typically less than 5ml per 100g of weld metal. This specification meets the stringent requirements of MIL-E-24403/1, making it highly suitable for industries where resistance to hydrogen-induced cracking is paramount, such as shipbuilding and offshore platform construction. The wire delivers mechanical properties that often exceed conventional E71T-1 wires, offering superior tensile strength and impact toughness.

This tubular wire is designed for all-position welding, including flat, horizontal, vertical-up, and overhead positions. The fast-freezing slag system supports the weld puddle effectively against gravity, allowing for high deposition rates even in out-of-position work. It is particularly effective for single and multiple pass applications on carbon steel. Industrial sectors such as pressure vessel manufacturing, railcar fabrication, and heavy earth-moving equipment production rely on the TM-771 for its consistent metallurgical quality and structural integrity.

By utilizing straight CO2 gas, operators can reduce shielding gas costs compared to Argon blends while still achieving a stable arc and excellent penetration profile. The S283319-K29 SKU represents a specific packaging configuration optimized for industrial wire feeders, ensuring smooth pay-off and reduced downtime associated with feeding issues.
