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

Precision Wire for Weathering Steel Applications

For professional welders tackling weathering steel projects, the ESAB Spoolarc 75 (ER80S-Ni1) is the go-to MIG wire that guarantees both performance and compliance. If you are welding on "Corten" style steels used in architectural facades, bridges, or heavy equipment, you know that matching the base metal is crucial. Spoolarc 75 is formulated to do exactly that. Once the finished weld is exposed to the elements, it develops the same rustic, protective oxide layer as the surrounding steel, ensuring your welds don't look like mismatched patch jobs years down the line. This 0.035-inch diameter wire on a 20kg spool is perfect for shop fabrication where long runs and high deposition rates are the norm.

Beyond its cosmetic advantages, Spoolarc 75 is a dream to run under the hood. It is designed for use with high-argon shielding gas blends, allowing you to achieve a buttery-smooth spray transfer mode. This means you get deep penetration, excellent sidewall fusion, and virtually no spatter to chip off later. The 1% nickel content doesn't just help with corrosion; it significantly boosts the toughness of the weld metal, especially in freezing conditions. This makes it an excellent choice for repairing mobile equipment or building structures that will face Canadian winters or other extreme climates.

Whether you are working in flat or horizontal positions, or using pulsed MIG for out-of-position work, Spoolarc 75 responds predictably to your settings. It meets the stringent AWS D1.5 Bridge Welding Code, so you can have total confidence in the metallurgical quality of your deposit. The copper coating on the wire ensures good electrical conductivity and protects the wire from rusting while in storage, ensuring that when you strike an arc, you get consistent ignition and burn-off. Upgrade your weathering steel welding game with a wire built for the job.
