Dengensha America’s capacitor discharge welder

Dengensha America Corp.’s Capacitor Discharge Welder (CDW) that minimizes heat transfer and distortion problems has a compact resistance welding control design. The welder handles weld current as high as 50 kA with a small 6-kVA power supply. High current in short bursts minimizes heat transfer and workpiece distortion, even when the power supply is unstable. The NDZ Series CDW has selectable current control modes that enable users to fine-tune weld quality. Modes include energy, peak current and constant current/time.
