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
