➤ When using, pay attention to monitoring the specific gravity of the flux and control it within the range of 0.79 ± 0.02 to ensure the best effect of the flux and minimize the defect rate.

➤ During non operating conditions, it is recommended to avoid contact between the flux and air as much as possible to avoid reducing the service life of the flux.

➤ If open type operation is used, attention should be paid to controlling the concentration of flux. When the specific gravity is too high, diluent should be added in a timely manner to avoid excessive welding residue and affecting post weld testing.
