ED561028 - Lincoln Electric ER70S-6 MIG Wire .025 (0.6mm) 2lb Spool

Premium Mild Steel MIG Wire for Professional Fabrication

The Lincoln Electric ER70S-6 MIG Wire (SKU: ED561028) represents the industry standard for high-quality mild steel welding applications. This 2lb spool features a wire diameter of 0.025 inches (0.6mm), making it an exceptional choice for precision work on thin-gauge materials where heat input control is critical. Manufactured to strict AWS A5.18 specifications, this solid wire is engineered to deliver consistent mechanical properties and superior arc performance in the Gas Metal Arc Welding (GMAW) process.

One of the defining characteristics of this ER70S-6 wire is its elevated chemical composition of silicon and manganese. These elements act as powerful deoxidizers, allowing the molten weld pool to wet out smoothly even when welding over light rust, mill scale, or oil. This makes the wire highly versatile for maintenance, repair, and operations (MRO) environments where surface preparation may not always be perfect. The copper coating on the wire surface serves a dual purpose: it enhances electrical conductivity at the contact tip for a stable arc, and it reduces friction within the liner to promote smooth, uninterrupted feeding.

This product is designed for use with DCEP (Direct Current Electrode Positive) polarity and requires external shielding gas. It performs exceptionally well with 100% CO2 for deep penetration or a 75% Argon / 25% CO2 blend for reduced spatter and a flatter bead profile. The 2lb spool size is specifically packaged to accommodate portable MIG welding machines and spool guns that utilize a 4-inch diameter hub, providing a compact solution for mobile welding tasks without compromising on industrial-grade wire quality.
