S249408-050 - Hobart Fabcor 86R Metal-Cored Wire .035 500lb X-Pak

Hobart Fabcor 86R .035" E70C-6M Welding Wire

Hobart Fabcor 86R is a high-performance carbon steel metal-cored wire meeting AWS E70C-6M H4 classifications. Engineered for the professional welder and industrial automation, this .035" wire combines the high deposition rates of flux-cored wires with the high efficiency and low slag of solid wires. The 500lb X-Pak drum configuration is specifically designed to support continuous, high-duty cycle operations, providing a twist-free payout that is essential for consistent arc placement in robotic applications.

Technically, Fabcor 86R excels in its wetting characteristics and gap-bridging capabilities. The metal powder core allows for a broader, more cone-shaped arc that penetrates deeply into the sidewalls, reducing the risk of lack-of-fusion defects. It is formulated to perform optimally with shielding gas mixtures containing 75% to 95% Argon (balance CO2), providing a spray transfer mode that is virtually spatter-free. This makes it an excellent choice for flat and horizontal welding positions where speed and bead appearance are critical.

The "R" in Fabcor 86R denotes its robust formulation, featuring enhanced deoxidizers (Silicon and Manganese) that effectively scavenge impurities from the weld pool. This capability allows welders to travel faster over mill scale and primed plates without sacrificing mechanical properties. With a typical tensile strength of 70,000+ PSI and excellent Charpy V-Notch impact toughness, this wire meets the rigorous demands of the railcar, shipbuilding, and heavy machinery sectors. The X-Pak drum ensures the wire remains protected and feeds smoothly over long conduit runs, maximizing arc-on time.
