S283215-K22 - Hobart TM-770 .052" Gas-Shielded Flux-Cored Wire, 10lb Spool

Hobart TM-770 .052" Flux-Cored Welding Wire (10lb Spool)

The Hobart TM-770 is a premium gas-shielded flux-cored wire designed to meet the rigorous demands of heavy industrial fabrication. Formerly known under the Tri-Mark brand, the TM-770 series has established a reputation for reliability and performance in structural steel applications. This 0.052-inch diameter wire comes in a convenient 10-pound spool, making it an excellent choice for portable wire feeders and smaller jobs where handling large drums or 33lb spools is impractical, yet high deposition rates are still required.

Engineered for all-position welding, the TM-770 excels in vertical-up and overhead positions thanks to its fast-freezing slag system. This characteristic allows operators to maintain control over the weld puddle, producing flat, consistent beads with minimal effort. The wire is formulated to operate with either 100% CO2 or a blend of 75% Argon and 25% CO2, providing flexibility depending on the available gas supply and desired arc characteristics. When used with mixed gas, operators will experience an even smoother arc and reduced spatter levels.

One of the standout features of the Hobart TM-770 is its mechanical integrity. It meets AWS E71T-1C/M and E71T-9C/M classifications, delivering high tensile strength and exceptional impact toughness even at lower temperatures. This makes it a preferred choice for critical applications such as shipbuilding, railcar manufacturing, and heavy equipment repair where weld failure is not an option. The wire produces low fume levels compared to conventional flux-cored wires, contributing to a better working environment for the welder.

At Josef Gas, we understand that consistency is key in industrial welding. The Hobart TM-770 delivers uniform wire feeding and arc stability, reducing downtime associated with contact tip burn-back or bird-nesting. Whether you are welding mild steel or fine-grain carbon steels, this wire provides deep penetration and excellent sidewall fusion, ensuring high-quality welds that pass radiographic inspection. Equip your shop with Hobart TM-770 for a versatile, high-performance solution to your flux-cored welding needs.
