Characteristics on UsageAT-YJ507 is alkalinity type CO2 shielded flux cored wire. There are characteristics such as steady arc, lower spatter loss, perfect joint appearance and less slag covering during welding, which all will lead perfect mechanical properties and fine crack resistance.
ApplicationsFor main structure of mild steel and 490MPa high tensile steel, widely used in welding of boiler, tanks, shipbuilding, bridges, constructions, and pipes.
Notes on UsageUse 100% CO2 gasCO2 mass flow controlled at 20-25L/min Wire extension: 15-25mm.DC+
