  • Capacitor Discharge Brochure


The unit offers consistent welding output for repeatable process results, with ultrafast rise time for conductive material welding. Built in the USA, featuring fully controllable dual pulse output, the CD-A1000A provides pulse shaping with 4 discrete pulse lengths, programmable squeeze and hold times and adjustable pulse separation. Furthermore, the units offer the ability to set limits around a schedule to prevent bad welds and a built-in peak current indicator which indicates the last weld peak current.

Key Features

  • Dual pulse function helps overcome surface inconsistencies
  • Built-in monitor measures peak current for both pulses for process monitoring
  • Process monitor features a color coded bar graph on the RUN screen that provides instant weld history of In Limit/ Out of Limit percentages to assess process performance
  • Upper and lower limits can be set for both pulses, with an option to inhibit Pulse 2 if Pulse 1 is out of limits. Prevents weld blow out
  • Upslope function allows gradual ramping of weld energy to alleviate weld splash
  • Automatic polarity switching between pulses provides even heating between electrodes and increases electrode life
  • Up to four software selectable pulse widths increases the range of welding applications and improves process optimization.
  • High resolution 6.5 in color display – large, clear 6.5 inch high resolution color display shows all weld information on the RUN screen
  • Efficient power electronics provide high repetition rates

Available Models

Replaces 100ADP and 125DP*

The CD-A125A Advanced Capacitive Discharge Welder features dual pulse output control, internal pulse monitoring, optional polarity switching and is automation capable.

The unit offers consistent welding output for repeatable process results, with ultrafast rise time for conductive material welding. Built in the USA, featuring fully controllable dual pulse output, the CD-A125A provides pulse shaping with 4 discrete pulse lengths, programmable squeeze and hold times and adjustable pulse separation. Furthermore, the units offer the ability to set limits around a schedule to prevent bad welds and a built-in peak current indicator which indicates the last weld peak current. The ability to change polarity – individual settings for positive, negative, or alternating polarity – allows for a way to balance weld nuggets and overcome the Peltier effect, as well as extend electrode life.

CD-A125A is automation ready and can be easily integrated into production lines. The unit can be programmed to communicate with a host computer or with an automation control system. Operators can set and store up to 63 schedules to quickly change between weld parameters. A schedule chaining feature lets users automatically switch between two different schedules. The power supplies enable rapid fire between pulses for quick welding of adjacent locations.

CD-A125A is ideal for battery tab welding, interconnects, honeycomb tacking and fine wire to pad applications.

*CD-A125A replaces 100ADP and 125ADP in the majority of applications, please consult AMADA WELD TECH for suitability of replacement prior to purchase.
