Under the control of the controller, the wire feeding motor stops working, and the heating gun reduces or closes flame. The rotary table rotates a station, the annular jewelry product subjected to heating welding is transferred to a discharging position C, the new annular jewelry clamped at the discharging position is transferred to a heating position again, heating welding is performed, and a new working step is started. When the operator takes out the finished product at the discharging position C, the operator can clamp the annular jewelry at the discharging position.
