ED037123 - Lincoln Electric UltraCore 71A85 1/16" Flux-Cored Wire, 33lb Spool

Technical Overview of Lincoln Electric UltraCore Flux-Cored Wire

The Lincoln Electric ED037123 is a premium gas-shielded flux-cored wire (FCAW-G) belonging to the renowned UltraCore family. Specifically identified as UltraCore 71A85, this consumable is engineered for the welding of mild steel in all positions. It is formulated to operate with a mixed shielding gas, typically 75% Argon and 25% CO2, which assists in producing a smooth spray-like transfer and optimal bead profile. The 1/16-inch (1.6 mm) diameter allows for higher deposition rates compared to smaller diameters, making it suitable for thicker base materials and heavy fabrication tasks.

This wire meets AWS A5.20 classifications, typically E71T-1M and E71T-9M, ensuring compliance with rigorous industry standards for tensile strength and impact toughness. The flux composition is designed to provide a fast-freezing slag, which supports the weld puddle in vertical-up and overhead positions, preventing sagging and ensuring a flat to slightly convex bead shape. The mechanical properties of the deposited weld metal are consistent and reliable, offering excellent ductility and crack resistance essential for structural integrity.

Packaged in a 33 lb (15 kg) spool, this product is compatible with standard industrial wire feeders. Storage and handling should follow standard practices for low-hydrogen consumables to prevent moisture pickup, although the wire design offers robust resistance to moisture-related defects. It is an ideal choice for shops requiring high throughput and code-quality welds.
