Compact Capacitor-Discharge Welder Boasts Simple Intuitive Control

Tuesday, February 14, 2017
 

NDZ-series capacitive-discharge welding (CDW) machines from Dengensha America, Bedford, OH, minimize heat transfer and distortion problems during resistance spot welding. The compact machines reportedly are easy and intuitive to set up, and offer fabricators numerous features designed to optimize weld quality.

The machines operate with weld current to 50 kA, yet require only a small 6-kVA power supply. High current in short bursts minimizes heat transfer and workpiece distortion, even when the power supply is unstable.

Along with offering fabricators a broad range of part-production potential, the CDW machines prove ideal for welding small projection parts of high-strength steels and aluminum alloys. Among the selectable current-control modes, which enable users to fine-tune weld quality: Energy, Peak Current and Constant Current/Time. For example, users can optimize weld quality by setting the first weld to the Energy mode for weld strength, and then the second weld to Constant Current mode for post-weld heattreatment.
