ER70S2 is a premium MIG & TiG wire for welding on all grades of mild and carbon steels, producing quality welds with minimal porosity. It is a triple deoxidized wire (Zirconium, Titanium, and Aluminum) making it an excellent choice for welding over rust and mill scale. No flux is required with this product.
TYPICAL APPLICATIONS：
pipes and offshore drilling rigs, structural steel work
