The Hobart Fabco 81K2-C is a premium gas-shielded flux-cored wire designed specifically for welding mild and low alloy steels using 100% CO2 shielding gas. This 1/16-inch diameter wire is packaged in a 33-pound spool, making it ideal for industrial fabrication environments where efficiency and weld quality are paramount. Engineered for all-position welding, the Fabco 81K2-C delivers consistent performance in flat, horizontal, vertical, and overhead positions, providing versatility for complex structural assemblies.
One of the standout features of this wire is its formulation for 100% CO2 gas. While many wires require mixed gases for optimal performance, the Fabco 81K2-C achieves excellent mechanical properties and arc stability with cost-effective carbon dioxide. This makes it a preferred choice for heavy equipment manufacturing, shipbuilding, and general construction where operating costs must be managed without sacrificing weld integrity. The wire produces a fast-freezing slag that supports the puddle well in out-of-position welds, ensuring a flat bead profile and easy slag removal.
Technically, this wire meets AWS E81T1-K2C specifications, indicating its suitability for applications requiring higher tensile strength and good low-temperature impact toughness. It is particularly effective for single and multiple pass applications. The 1/16" diameter allows for higher deposition rates compared to smaller wires, increasing productivity on thicker plate materials. Welders will appreciate the smooth arc characteristics and low spatter levels, which reduce post-weld cleanup time.
