“…There are not obvious changes in the making arc and the breaking arc durations before and after welding occurrence [4]. K. Hotta demonstrated that the increase of arc energy on the contact surface would increase the welding force, and the real welding area accounted for about 25% to 40% of the melting area [5]. T. Mutzel found that different base metal oxides and their total content are of significant influence for weld break forces [6].…”

In order to analyze the making arc characteristics of AgSnO<sub>2</sub> contact, experiments were carried out with a self-developed experimental equipment. It was found that contact resistance had no obvious change with the increase of the number of experiments.In the later stage of the experiment, the contact bounces occurred during the contact closing process, which not only prolonged the making arc duration, but also increased making arc energy. When the contact was eroded to a certain extent by arc, making welding occurs.
