In this method, a capacitor is used to store energy for quick release. Capacitor Discharge Spot Welder provides a large amount of weld energy with power adjustment. This process has many advantages over other welding types and ideal product for many spot welding application. As compared to other spot welder sparkweld’s Capacitor Discharge Spot Welder produces strong, clean and repeatable weld and also provide ample power for a large spectrum of the application at an affordable price. Weld formation takes place in milli seconds, in first few seconds it heats the weld area to eliminate surface contaminants and seat welding electrodes and then makes a higher energy weld which is secure and strong. Capacitor Discharge Spot Welder delivers repeatable welds during voltage fluctuation as weld energy is stored before use.
