S247012-029 - Hobart FabCO TR-70 .045 Flux-Cored Wire 33lb Spool

Technical Overview: Hobart FabCO TR-70

The Hobart FabCO TR-70 is a gas-shielded, flux-cored wire designed for the welding of mild and medium carbon steels. Classified under AWS A5.20 as E70T-1C H8 and E70T-9C H8, this wire is engineered for high-performance fabrication in the flat and horizontal positions. It utilizes a tubular wire construction filled with fluxing agents that provide excellent arc stability, deep penetration, and superior mechanical properties. The wire diameter is 0.045 inches, packaged in a standard 33-pound spool, making it compatible with most industrial wire feeders.

Optimized for use with 100% CO2 shielding gas, the FabCO TR-70 delivers a spray-like transfer which contributes to high deposition rates and efficiency. The slag system is formulated to be self-peeling or easily removable, significantly reducing inter-pass cleaning time in multi-pass applications. The H8 designation indicates a controlled diffusible hydrogen content of less than 8ml per 100g of weld metal, reducing the risk of hydrogen-induced cracking in heavy structural applications.

This consumable is particularly well-suited for single and multi-pass welding on plate steel where high travel speeds are required. It exhibits excellent impact toughness, meeting Charpy V-Notch requirements at -20°F (-29°C). The wire requires Direct Current Electrode Positive (DCEP) polarity. It is widely specified for structural steel erection, heavy equipment manufacturing, and general fabrication where vertical-up welding is not required.
