ED033755CAN - Lincoln UltraCore HD-C .045 Flux-Core Wire 33lb Spool

Technical Overview of Lincoln UltraCore HD-C

The Lincoln UltraCore® HD-C .045" is a premium gas-shielded flux-cored wire engineered to meet the rigorous demands of the shipbuilding and heavy fabrication industries. Identified by the internal SKU ED033755, this consumable is formulated specifically for use with 100% CO2 shielding gas. By optimizing the flux chemistry for carbon dioxide, Lincoln Electric provides a cost-effective solution that does not compromise on mechanical properties or arc performance. The wire meets AWS A5.20 classifications E71T-1C-H8 and E71T-9C-H8, ensuring it delivers the requisite tensile strength and Charpy V-Notch toughness required for critical structural applications.

One of the defining characteristics of the UltraCore HD-C series is its high deposition rate capability. In industrial environments where throughput is critical, such as shipyard panel lines or structural steel erection, the ability to deposit more metal per hour significantly impacts project timelines. The "HD" designation underscores this performance metric, while the "C" explicitly denotes its CO2 optimization. Despite its high deposition characteristics, the wire maintains a fast-freezing slag system. This rheological property allows operators to control the weld puddle effectively in out-of-position welds, including vertical-up and overhead, making it a truly versatile all-position wire.

Metallurgically, the wire produces a mild steel deposit with controlled diffusible hydrogen levels (H8 designation), reducing the risk of hydrogen-induced cracking in thicker plate sections. The slag system is designed to be self-peeling in many joint configurations, which reduces inter-pass cleaning time and improves the overall duty cycle of the welding operation. The wire feeding characteristics are enhanced by Lincoln's proprietary manufacturing processes, ensuring consistent diameter and lubricant distribution to minimize liner wear and contact tip erosion.

For procurement and inventory management, the ED033755 comes in a standard 33lb (15kg) spool, compatible with most industrial wire feeders. It is an ideal choice for shops looking to standardize on a single wire that offers both the economy of CO2 shielding gas and the performance of a premium flux-cored consumable.
