Amada Weld Tech’s Benchmark® brand CD-P Series capacitor discharge welding power supplies are field proven solutions for welding applications which require precision, repeatability and low heat affected zone.

These power supplies deliver high peak current in short weld pulses which are suitable for difficult to weld materials like hard, high strength, stamped or drawn steel. Allows the use of much higher currents with low heat propagation preventing oxidation and surface decarburization resulting in joints that exceed manufacturers’ required pushout and torque requirements without damaging the parts. Consistent and repeatable results eliminate the need for post-weld inspections, saving time and money.

CD-P welding power supplies are typically used in the microelectronic, medical, military, sensor and automotive industries which utilize a vast range of materials like kovar, invar, cold rolled steel, hot stamped boron steel like USIBOR, stainless steel and nickel.

• Capacitor discharge (CD) technology supplies short, high energy welding pulses which localize heat in the weld zone, reducing heat build-up in parts like sensitive microelectronic packages
• Wide range of CD power supplies from CD-P3000A (3,000 Joule) to CD-P9000A (9,000 Joule) configuration
• “Weld inhibit” function accepts input from atmospheric enclosure instruments, such as oxygen analyzers and moisture monitors for integrated process control
• “Weld fire” lockout monitors the capacitor bank charge and prevents firing if the energy level differs from the set point, ensuring repeatable weld pulses
• Efficient stored energy design provides stable, consistent output pulses which are not affected by AC input power fluctuations

• Straightforward operation and control is easy to learn and understand
• Active Discharge feature automatically activated when reducing power setting (no need to reset the power supply to discharge excess power)
• Separate power control board for easy calibration and repair
• Built-in air-cooling for improved air circulation and performance even in harsh environments
• Stop function inhibits firing, disables charging and initiates capacitor discharge with audible alarm
• Analog input voltage control allows power setting from an external device
• Analog output monitors the capacitor voltage
• Built-in thermal overheat safety weld inhibit switch
• Utilizes a high efficiency matched weld transformer
