DC Capacitor Welding Equipment for Kitchen Products Pan and Pot DESCRIPTION 1. Store energy welding machine is also called the capacitor store energy welding machine, to use the capacitor store energy is the main working principle, when energy can make a small area of solder melting and the instantaneous discharge, the welding time is very fast, about 3/1000 second, and the welding time is not adjust. 2. Capacitor discharge spot welder uses capacitor to store energy and to
