The Hobart TM-771 1/16" Flux-Cored Welding Wire is a high-performance consumable designed for demanding industrial applications. Engineered to meet AWS E71T-1C and E71T-1M classifications, this wire provides exceptional mechanical properties and reliability for structural steel fabrication, shipbuilding, and heavy equipment manufacturing. The 1/16" (1.6 mm) diameter is optimized for higher deposition rates while maintaining the ability to weld in all positions, making it a versatile choice for complex assemblies.
One of the defining characteristics of the TM-771 is its fast-freezing slag system. This feature significantly enhances puddle control, particularly in vertical-up and overhead welding scenarios, allowing operators to maintain consistent bead profiles without excessive manipulation. The wire is formulated to operate with both 100% CO2 and 75% Argon / 25% CO2 shielding gas mixtures, offering fabrication shops the flexibility to optimize for cost or arc characteristics depending on the specific project requirements. With a low hydrogen designation (H8), it minimizes the risk of hydrogen-induced cracking, ensuring the integrity of critical welds.
Packaged in a substantial 50 lb spool, this product is intended for high-volume production environments where downtime for spool changes must be minimized. The wire feeds smoothly through standard industrial wire feeders, reducing the likelihood of bird-nesting or liner clogging. Its formulation also results in lower fume generation compared to many conventional flux-cored wires, contributing to a better working environment. Whether used for railcar construction or general structural fabrication, the Hobart TM-771 delivers consistent, X-ray quality welds with excellent impact toughness.
