1212F05 - ESAB Spoolarc 82 ER70S-3 MIG Wire 0.035" 20kg Spool

Premium ER70S-3 Mild Steel MIG Wire

The ESAB Spoolarc 82 is a high-performance copper-coated solid wire formulated to meet the AWS A5.18 classification of ER70S-3. Engineered for the welding of mild and low-alloy steels, this wire is particularly effective on clean materials where heavy deoxidization is not required. Unlike ER70S-6 wires which contain higher levels of manganese and silicon to combat rust and mill scale, the Spoolarc 82 (ER70S-3) chemistry is optimized to prevent the formation of excessive silicon islands, making it a superior choice for applications requiring painting or plating immediately after welding.

This 20kg spool of 0.035" (0.9mm) wire is precision-wound to ensure consistent feeding characteristics, reducing downtime associated with bird-nesting or liner clogging. The copper coating enhances electrical contact at the contact tip, promoting a stable arc and extending the life of your consumables. It is designed for use with argon/CO2 shielding gas mixtures or 100% CO2, providing versatility across various welding setups. The wire exhibits excellent wetting action, resulting in flat, smooth bead profiles that require minimal grinding.

Spoolarc 82 is rigorously tested and carries approvals from major certifying bodies including the American Bureau of Shipping (ABS), Lloyds Register, and the Canadian Welding Bureau (CWB). This makes it suitable for code-compliant work in structural fabrication, pressure vessels, and general manufacturing. Its controlled chemical composition ensures reliable mechanical properties, delivering tensile strengths consistent with the 70ksi class requirements while maintaining good ductility.
