OVERVIEW

Premium Mild Steel MIG Wire for Professional Fabrication

The Lincoln Electric SuperArc L-56 is the industry standard for premium copper-coated mild steel MIG wire. Engineered with high levels of manganese and silicon deoxidizers, this ER70S-6 wire is specifically designed to handle medium to heavy mill scale and surface contaminants that often plague general fabrication projects. Whether you are welding on structural steel, automotive frames, or sheet metal, the L-56 formula ensures a clean, sound weld deposit with minimal porosity.

One of the standout features of the SuperArc L-56 is its exceptional toe-wetting capability. This characteristic allows the weld puddle to flow smoothly into the base material, creating a flat, aesthetically pleasing bead profile that requires less post-weld grinding. The strict quality control during manufacturing guarantees consistent wire diameter and chemistry, which translates to stable arc performance and reliable feeding through your MIG gun liner.

This 12.5 lb spool is sized perfectly for portable wire feeders and smaller shop machines that utilize an 8-inch diameter spool hub. The copper coating not only protects the wire from oxidation during storage but also enhances electrical conductivity and reduces friction, significantly extending the life of your contact tips. Suitable for all transfer modes—including short-circuiting, globular, axial spray, and pulsed spray—the Lincoln SuperArc L-56 is the versatile choice for welders who demand consistency and quality in every pass.

FAQ

SuperArc L-56 performs best with 100% CO2 for deeper penetration or a 75% Argon / 25% CO2 mix for a smoother arc and less spatter.

No, this is a solid MIG wire (ER70S-6) and requires an external shielding gas to weld.

The 12.5 lb spool typically has an 8-inch diameter, fitting most compact and portable MIG welders.

Yes, the high silicon and manganese content allows it to tolerate medium to heavy mill scale and light rust better than ER70S-3 wires.

This wire requires DC+ (Direct Current Electrode Positive), also known as DCEP or reverse polarity.

This wire is classified as AWS A5.18 ER70S-6.

Yes, as a solid wire, it can be used in all positions (flat, horizontal, vertical, overhead), typically using the short-circuit transfer mode for out-of-position work.

Yes, Lincoln SuperArc L-56 is copper coated to improve feedability and electrical contact.
