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. This makes it suitable for welding difficult-to-weld non-ferrous metals with good thermal and electrical conductivity, and particularly ideal for stainless steel products and products with high requirements for the welding surface.

Stainless steel, silver, and other alloy materials.

Industrial production and manufacturing:
such as welding of stainless steel cookware handles, cooking pot handles, stainless steel strips, battery welding, and electronic components soldering.
