Lincoln Electric ED031663 UltraCore 71A85 Flux-Cored Welding Wire .045" 33 lb Fiber Spool

The Lincoln Electric UltraCore 71A85 (ED031663) is a premium gas-shielded flux-cored welding wire (FCAW-G) engineered for outstanding performance with high-argon mixed shielding gas. Offered in a 0.045-inch (1.1 mm) diameter on a 33 lb fiber spool, this wire delivers consistent, high-quality welds on carbon steel across all positions.

Specifically optimized for use with 75–85% Argon/balance CO2 shielding gas, the UltraCore 71A85 provides superior arc stability, smooth bead appearance, and a fast-freezing slag system ideal for out-of-position welding. It is a preferred choice for shipbuilders, structural fabricators, and heavy industrial applications requiring a reliable E71T-1 wire on high-argon gas blends.
