Surface tension of liquid metal varies in oxide condition for a short time since it is sensitive to surface oxidation. The temporally varying surface tension, i.e. dynamic surface tension, has great impact on many industrial processes relating to liquid metal. In this study, the dynamic surface tension of solder is measured by capillary jet method. Measured results indicate fast decrease from initial value to equilibrium surface tension for 2 - 4ms under the oxygen concentration of around 0.02%.
