Capacitor Discharge Spot Welder

Capacitor discharge spot welding machine, also referred as capacitive discharge or CD welding, stores energy from a capacitors bank which on discharging, release the current by very fast pulse. In comparison to other welding methods such as AC spot welding, it has a lower instantaneous power demand from the grid, balanced load among phases, high power factor, and the ability to provide concentrated energy to the welding area. As a result, it produces weldments with excellent surface quality and minimal deformation.
