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
- Triple deoxidized (Aluminum, Titanium, Zirconium) ER70S-2 solid wire designed for welding over rust and mill scale without sacrificing weld quality
- Very low nitrogen in the steel to help achieve impact resistance above 70 ft•lbs @-20°F
- Microguard® Ultra provides superior feeding, arc stability and improved protection against corrosion
- Copper coating promotes excellent arc starting and extremely low contact tip wear.
- Very low spatter levels and fume emissions.
- 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
- 100% CO2, 75-95% Argon/ Balance CO2, Flow Rate: 30-50 CFH
