OVERVIEW

Experience Superior Arc Control with Lincoln SuperArc L-59

Upgrade your welding arsenal with the Lincoln Electric SuperArc® L-59®, a 0.035-inch MIG wire designed for welders who demand precision and performance. This ER70S-6 solid wire is a staple in the welding industry, known for its forgiving arc and exceptional versatility. If you are tired of dealing with erratic feeding, burn-backs, or excessive spatter, the L-59 is the solution you have been looking for. Lincoln Electric has manufactured this wire with tight tolerances on diameter and cast, ensuring that it feeds smoothly through your gun, whether you are running a short 10-foot whip or a longer conduit system.

The "SuperArc" name is synonymous with quality, and the L-59 variant specifically targets improved contact tip life and arc stability. The micro-guard copper coating prevents oxidation on the wire during storage and facilitates excellent electrical conductivity during the weld. This results in a crisp, energetic arc that digs deep when you need penetration but remains controllable for out-of-position work. For welders working on thinner gauges or sheet metal, the 0.035" diameter strikes a perfect balance, offering enough deposition for structural work while being manageable on lighter materials.

Welders Supply Company recommends the SuperArc L-59 for its ability to produce professional-looking results with minimal post-weld cleanup. The high silicon content helps float impurities to the surface, leaving you with a clean, solid bead. It is compatible with standard DC+ (reverse polarity) setups and works effectively with a variety of shielding gases. The 44 lb fiber spool is designed to fit most industrial wire feeders, providing a long-lasting supply of wire that keeps you under the hood and welding longer. Choose Lincoln Electric's L-59 for a wire that works as hard as you do.

Features & Benefits

  • Enhanced Feedability: Copper coating and precise winding reduce tangles and bird-nesting.
  • Versatile Shielding Gas: Performs well with both CO2 and mixed gases.
  • Clean Welds: Deoxidizers combat contaminants on dirty steel.
  • Eco-Friendly Packaging: Fiber spool reduces plastic waste.

FAQ

SuperArc L-59 is designed to operate with either 100% CO2 or Argon/CO2 blends (such as C25). 100% CO2 provides deeper penetration, while Argon blends offer a smoother arc and less spatter.

Yes, as an ER70S-6 class wire, it contains higher levels of manganese and silicon which act as deoxidizers, allowing it to weld through light to moderate rust and mill scale effectively.

This solid MIG wire requires Direct Current Electrode Positive (DCEP), also known as reverse polarity.

While both are ER70S-6 wires, L-59 is engineered with specific chemistry and surface characteristics to optimize feedability and contact tip life, making it particularly popular for high-production and robotic applications.

This is a standard 12-inch diameter industrial spool. It fits most industrial wire feeders and larger MIG machines. It will not fit inside small hobbyist welders that only accept 2lb or 10lb spools without an external adapter.

Yes, this product comes on a fiber spool, which is more environmentally friendly and easier to recycle than traditional plastic spools.

This specific product is 0.035 inches (0.9 mm) in diameter.

Yes, SuperArc L-59 features a high-quality copper coating that improves electrical conductivity and wire feeding performance.
