Capacitive Discharge Welding Power Supplies

Capacitive Discharge (CD) power supplies provide a direct current pulse. The energy of the pulse can be pre-set through the controlled charging of a capacitor. The pulse shape can only be influenced to a limited extend. In many cases, these power supplies cover a wider spectrum of technological.

Advanced Capacitive Discharge Welders - 125, 300, 1000 ADP Series

Amada Miyachi’s range of Advanced Dual Pulse Capacitive Discharge welders provides a new level of welding performance, with both advanced process monitoring and a simplified user interface. Its all-new design includes a proprietary charging unit to improve pulse-rise times and repetition rates. The built-in weld monitor with color display provides information at a glance on weld and process performance. Unique features such as programmable pulse polarity and upslope enable fast, easy setup and ensure that nugget formation and electrode wear are even during series welding, as well as alleviating weld splash. The ADP Series welders are ideal for welding conductive materials in applications such as the spot welding of batteries, tab welding, honeycomb welding and more!


Specifications

  • Built-in current monitor
  • Set pulse limits
  • Four pulse widths with fast rise times
  • Programmable, automatic polarity switching
  • Upslope function
  • Quick-view color screen

 

Dual Pulse Capacitive Discharge Welders - 125DP, 250DP

The Dual Pulse Spot Welder Series are capacitive discharge power supplies (CD welder) that have been designed specifically for precision resistance spot welding applications such as battery pack welding. They are controlled by microprocessor, store multiple weld schedules, and provide consistent weld energy to the parts being joined. MIYACHI UNITEK’s dual-pulse spot welders deliver high-peak energy with fast rise times. This is particularly important when welding highly conductive materials such as copper and brass. The control system provides a highly stable output, independent of line voltage fluctuations which results in repeatable energy delivery from weld to weld. The short weld times of the Dual Pulse Series result in minimal deformation and marking to parts.


Specifications

  • Dual Pulse function eliminates surface inconsistencies
  • Microprocessor controlled
  • Optional built-in weld monitor
  • Up to 128 programmable weld schedules
