Hobart FabCOR 86R: Superior Performance on Mill Scale

Hobart FabCOR 86R is a high-performance metal-cored welding wire (AWS E70C-6M H4) designed to maximize productivity in the fabrication of mild steel. This specific SKU comes in a substantial 750 lb drum, featuring a 1/16-inch diameter wire ideal for heavy-duty applications requiring high deposition rates and deep penetration. The "R" in 86R signifies its robust formulation, specifically engineered with elevated levels of silicon and manganese deoxidizers. These elements make the wire exceptionally forgiving when welding over mill scale, rust, and other surface impurities, often eliminating the need for grinding or sandblasting prior to welding.

Optimized for Automation and Robotics
The 750 lb drum packaging is a strategic choice for automated and robotic welding cells. The continuous feed provided by this bulk package minimizes the downtime associated with swapping out smaller spools, thereby increasing arc-on time and overall operational efficiency. The wire's excellent feedability and consistent arc characteristics ensure smooth operation through long conduit runs typical in robotic setups. Furthermore, the FabCOR 86R produces very low spatter levels and minimal slag islands, which is crucial for multi-pass welding where inter-pass cleaning needs to be kept to a minimum.

Technical Advantages
Compared to solid ER70S-6 wires, FabCOR 86R offers higher travel speeds and deposition rates, allowing for faster completion of long welds on heavy sections. It is designed for use with shielding gas mixtures ranging from 75% to 95% Argon with a CO2 balance. This gas flexibility allows welders to fine-tune the arc for penetration profile and bead appearance. The wire creates a spray transfer mode that is smooth and stable, resulting in flat weld beads with excellent tie-in at the toes. It is suitable for both single and multiple pass applications in the flat and horizontal positions.

Applications and Industries
This wire is widely used in the manufacturing of heavy equipment, agriculture machinery, railcars, and structural steel fabrication. Its ability to handle higher currents (DCEP) makes it a powerhouse for thick plate welding. If your shop is looking to improve cycle times and reduce pre-weld preparation on scaled steel, Hobart FabCOR 86R is the industrial standard solution.
