DETAILS

Lincoln Electric's triple deoxidized premium copper coated MIG wire, SuperArc® L-52® is an excellent choice for making high quality, high toughness welds, even when welding over rust and mill scale

Features

  • A triple deoxidized (Aluminum, Titanium, Zirconium)ER70S-2 solid wire designed for welding over rust and mill scale without sacrificing welding quality
  • Very low Nitrogen in the steel makes it easy to achieve impact resistance above 70 ft•lbs @ -20F
  • MicroGuard® Ultra provides superior feeding, arc stability and improved protection against corrosion
  • Other characteristic features include excellent start properties, extremely low contact tip wear, low levels of spatter and fume emission
  • Preferred for all position welding of different sizes of pipe

Typical Applications

  • Root, fill and cap pass welding for Piping Industries
  • Metal Fabrication
  • Power Generation

Welding Positions

  • All

Shielding Gas

  • Mixed Shielding Gas|100% CO2
