Note On Usage:
1.Apply CO₂gas shield,and CO₂gas purity is above 99.98%.
2.The CO₂shield gas flow during welding should be controlled between 18-25L/min. 3The extension elongation of welding wire should be controlled between 15~25mm.
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.
