Characteristics on Usage High-basic bonded type flux having High Tensile strength and good impact value at low temperature. Because of insensitivity to rust, scale, primer on the surface to be welded, it has excellent X-ray characteristics and slag removal. Note on Usage 1. Dry the flux at 300~350 (572~662 ) for 60minutes before use. 2. When the flux height is excessive, poor bead appearance may occur. 3. Remove rust, scales, oil, paint, water, dirt and slag of tack welds from the groove to obtain sound weld metal.
