Description: SJ301 is a bonded type Si-Ca neutral flux with ball form granual of brown color, about 10-16 mesh in size. It can be used on AC or DC power source and also can be used on large current. Its unique features include stable arc, easy slag removal and smooth bead appearance.
Application: In combination with H08A, H10Mn2 wires, this flux is suitable for welding of structures boilers, pipelines.
Guidelines For Usage:
1.Dry the flux at 300∼350°C for 2 hours before use.
2. Completely remove rust, oil and dirt from the groove surface prior to welding.
