ED561130 - Lincoln SuperArc L-59 0.035" MIG Wire - 500lb Drum

Superior Arc Control and Feedability for Professional Welders

When your weld quality depends on precision and consistency, Lincoln Electric SuperArc® L-59® is the wire you trust. This 0.035" (0.9 mm) solid MIG wire is an ER70S-6 classification, engineered to deliver a smooth, stable arc with minimal spatter. The "L-59" designation is synonymous with high performance, featuring a chemical composition rich in manganese and silicon. These deoxidizers aggressively scavenge impurities from the weld puddle, allowing you to lay down sound beads even on steel with light rust or mill scale.

One of the standout features of the L-59 is its wetting action. The puddle is fluid and responsive, washing in effectively at the toes of the weld to create a flat, smooth bead profile that requires little to no post-weld grinding. This makes it an excellent choice for applications where aesthetics and structural integrity are paramount. The copper coating isn't just for looks; it improves electrical conductivity for better arc starts and protects the wire from corrosion during storage.

For welders operating robotic cells or using long gun cables, feedability is critical. The ED561130 comes in a 500 lb Accu-Trak® drum, designed to pay out wire straight and tangle-free. Lincoln's MicroGuard® surface treatment reduces friction inside the liner and prevents copper flaking, which is a common cause of contact tip clogging. Whether you are running 100% CO2 for penetration or an Argon blend for a spray transfer, the SuperArc L-59 adapts to your parameters to deliver professional results every time.

Technical Advantages

• Excellent Deoxidizing: Handles light surface contaminants better than S-3 wires.
• Low Spatter: Reduces cleanup time and improves deposition efficiency.
• Extended Consumable Life: High-quality copper coating reduces tip wear and arc instability.
