S288115-050 - Hobart Fabco 81K2-C .052 Flux-Cored Wire 500lb Drum

Hobart Fabco 81K2-C .052" Flux-Cored Wire (500lb X-Pak)

The Hobart Fabco 81K2-C is a premium gas-shielded flux-cored wire designed to meet the rigorous demands of heavy industrial fabrication. Engineered specifically for use with 100% CO2 shielding gas, this wire offers a cost-effective solution without compromising on mechanical properties or weldability. The .052-inch diameter is a versatile choice for structural steel, shipbuilding, and heavy equipment manufacturing, providing a balance between deposition rate and puddle control. This specific package comes in a 500lb Exacto Pak (X-Pak), which is ideal for high-volume manufacturing environments utilizing automation or long-run manual welding stations, significantly reducing downtime associated with spool changes.

One of the standout features of the Fabco 81K2-C is its exceptional impact toughness at low temperatures. Rated to maintain high Charpy V-Notch impact values even at -40°F (-40°C), it is the preferred choice for offshore platforms, storage vessels, and other critical structures exposed to harsh environments. The wire formulation produces a fast-freezing slag, which supports the weld puddle effectively in all positions, including vertical-up and overhead. This characteristic allows welders to achieve flat, consistent bead profiles with minimal effort, reducing the risk of defects such as lack of fusion or slag inclusions.

In addition to its mechanical superiority, the Fabco 81K2-C is designed with the operator in mind. It generates lower fume levels compared to many conventional flux-cored wires, contributing to a cleaner working environment. The arc is smooth and stable, producing low spatter levels that minimize post-weld cleanup. The slag is self-peeling in many instances or easily removed with light chipping, further enhancing productivity. Whether you are welding mild steel or low-alloy steels requiring 80,000 psi tensile strength, the Hobart Fabco 81K2-C delivers reliability and performance that professional fabricators trust.
