S225629-H82 - Hobart Fabshield XLNT-6 3/32" Self-Shielded Flux-Cored Wire 20lb Spool

Technical Overview of Hobart Fabshield XLNT-6

The Hobart Fabshield XLNT-6 is a premium 3/32-inch diameter self-shielded flux-cored welding wire designed for high-demand structural applications. Engineered to meet AWS E70T-6 classifications, this wire provides exceptional mechanical properties, specifically focusing on high deposition rates and superior impact toughness at low temperatures. It is formulated for single and multiple pass welding in the flat and horizontal positions, making it a staple in heavy industrial fabrication sectors such as bridge construction, shipbuilding, and offshore rig assembly.

One of the defining technical characteristics of the XLNT-6 is its ability to maintain excellent arc stability while delivering high deposition rates, which significantly improves throughput in large-scale welding operations. The wire operates on Direct Current Electrode Positive (DCEP) and does not require external shielding gas, simplifying equipment setup for field operations. The chemical composition is optimized to resist cracking and provide reliable Charpy V-Notch impact values, often meeting or exceeding 20 ft-lbs at -20°F, which is critical for structures subject to dynamic loading or harsh environmental conditions.

This specific SKU (S225629-H82) comes in a 20 lb Vacuum Packed Spool (VPSP). The vacuum packaging is a critical quality control feature, protecting the hygroscopic flux core from moisture absorption during storage and transport. This ensures that the wire delivers low hydrogen weld deposits (typically H8 or better) right out of the box, reducing the risk of hydrogen-induced cracking in thick structural steel sections. The 3/32" diameter allows for substantial current carrying capacity, enabling deep penetration and robust fusion profiles required in heavy-duty structural welds.
