Description: SJ402 is a bonded flux of manganese silicon type acid welding flux, its alkalinity is about 0.7.It is spherical, size 10-60 mesh and can be used on AC or DC power source. It provides good welding usability, its unique features include stable arc and bead appearance is smooth .SJ402 is a kind of rust-proofing welding flux and is not sensitive to greasy dirt; oxidize layer and the rust for welding place. The Welding flux is good to tide-proofing and pellet strength is high. In welding course, flux's consumption is measured less.
Application: It is suitable for welding sheet and medium thickness steel plate, especially for sheet higher fast welding. In combination with H08A wires, it can weld ordinary steel structure and some low alloy steel column and pipeline.
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.
