Note On Usage:
1.The welding flux should be used at 250-400℃ for baking 1 to 2 hours.Welding wire should be dry without oil or rust.
2.Please remote the impurities e.g.rust,oil contaminant and water etc.on welding workpiece prior to welding.
Used for high eficiency welding in all positions with excellent welding performance such as warming electric arc,little spatters,beautiful seam forming and easily moved slag.Suitable for welding of 590 MPA high strength steel,steel structure,bridge,steel pipes,railway vehicle,and construction equipment etc.
