13P2F05 - ESAB Spoolarc 75 ER80S-Ni1 MIG Wire .035 44lb Spool

Industrial Grade Weathering Steel MIG Wire

The ESAB Spoolarc 75 is a premium low-alloy solid MIG welding wire classified as ER80S-Ni1, specifically engineered for the rigorous demands of heavy structural fabrication. This 20kg (44lb) spool of 0.035-inch wire is the preferred choice for industries requiring compliance with AWS D1.1 and D1.5 structural welding codes. It is formulated with approximately 1% nominal nickel content, which provides two critical advantages: enhanced atmospheric corrosion resistance and superior impact toughness at low temperatures. These properties make Spoolarc 75 an essential consumable for the fabrication of bridges, transmission towers, and other outdoor infrastructure exposed to harsh environmental conditions.

One of the standout features of Spoolarc 75 is its ability to produce weld deposits that chemically and physically match the characteristics of weathering steels, such as ASTM A588 and A709 (commonly known as Corten). When these steels are left unpainted to develop their protective patina, standard carbon steel welds would stand out visually and corrode at a different rate. Spoolarc 75 ensures that the weld seam weathers identically to the base metal, maintaining both the structural integrity and the aesthetic continuity of the project. This makes it a staple inventory item for fabricators working on architectural steel and highway bridge projects.

Operational efficiency is key in industrial environments, and Spoolarc 75 delivers with excellent feedability and arc stability. It is designed to operate with binary shielding gas mixtures, typically Argon/CO2 (with a minimum of 75% Argon) or Argon/Oxygen blends. The wire produces a smooth spray transfer that minimizes spatter and reduces post-weld cleanup time. Its mechanical properties typically exceed 80,000 psi tensile strength, providing a robust safety margin for critical load-bearing applications. For workshops handling heavy mobile equipment or ship and barge building, this wire offers the reliability and consistency required to meet strict quality assurance standards.
