Hobart TM-771 .052" Flux-Cored Welding Wire

The Hobart TM-771 is a premium gas-shielded flux-cored wire designed to exceed the expectations of professional welders in heavy industrial environments. Engineered for use with 100% CO2 shielding gas, this .052-inch diameter wire delivers a welding experience characterized by a soft, quiet arc and virtually zero spatter. This exceptional operator appeal makes it a favorite for long shifts where ease of use and arc stability are paramount to maintaining productivity and weld quality.

One of the standout features of the TM-771 is its superior mechanical properties, which often surpass those of conventional E71T-1 classification wires. It is specifically formulated to produce weld deposits with very low diffusible hydrogen levels—typically less than 5ml per 100g of weld metal. This low-hydrogen characteristic is critical for preventing cracking in high-stress applications and ensures the wire meets stringent industry standards, including the requirements of MIL-E-24403/1. This makes the TM-771 an ideal choice for industries where weld integrity cannot be compromised.

Versatility is at the core of the Hobart TM-771's design. It is an all-position wire, allowing operators to perform high-quality welds in flat, horizontal, vertical, and overhead positions without changing consumables. Whether tackling single-pass fillets or complex multiple-pass groove welds, this wire maintains consistent penetration and bead appearance. The fast-freezing slag system supports out-of-position work while remaining easy to remove, further reducing cleanup time and labor costs associated with post-weld grinding.

Packaged in a 33-pound spool, this wire is optimized for industrial wire feeders and heavy-duty fabrication cycles. It is extensively used in sectors such as shipbuilding, pressure vessel manufacturing, and offshore construction. By combining high-performance mechanical specs with excellent runnability, the Hobart TM-771 ensures that fabricators can achieve code-quality results efficiently, even in the most demanding structural steel and heavy equipment applications.
