Product Description
Lincoln Electric SuperArc® L-56 MIG Wire (AWS ER70S-6)
Premium Performance for Demanding Welds
The Lincoln Electric SuperArc® L-56 is a copper-coated mild steel MIG wire designed to deliver outstanding performance on metals with medium to heavy mill scale. Its high levels of manganese and silicon deoxidizers ensure cleaner welds, excellent toe wetting, and smooth bead appearance even on challenging base materials.
Versatile Welding Performance
This MIG wire is engineered for flexibility across a range of welding modes, including short-circuiting, globular, axial spray, and pulsed spray transfers. The result is consistent feeding, stable arcs, and reduced downtime for both manual and robotic applications.
Durable Coating and Long-Lasting Consumables
The copper coating improves conductivity, promotes smooth wire feeding, and extends the life of contact tips. Welders benefit from fewer interruptions, better arc starts, and reduced maintenance costs.
Strong Mechanical Properties
SuperArc® L-56 meets AWS ER70S-6 standards and provides excellent strength and toughness. Typical properties include a tensile strength of approximately 81 ksi, a yield strength of around 64 ksi, and elongation of nearly 29%, with strong impact resistance at low temperatures.
