Capacitive Discharge Power Supplies

Amada Miyachi America, Inc. has released the new CD-A series of advanced capacitive discharge welders. They feature dual pulse output control, internal pulse monitoring, optional polarity switching and are automation capable. They are suitable for battery tab welding, interconnects, honeycomb tacking and fine wire to pad applications.

The new units offer consistent welding output for repeatable process results, with fast rise time for conductive material welding. Featuring fully controllable dual pulse output, the CD-A series provide pulse shaping with four discrete pulse lengths, programmable squeeze and hold times and adjustable pulse separation for process optimization. Furthermore, the units offer the ability to set limits around a schedule to prevent bad welds and a built-in peak current indicator that indicates the last weld peak current. The ability to change polarity-using 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. "Pair the CD-A with an Amada Miyachi weld head with EZ-AIR operation for control of weld force for repeatable, consistent welding," said a company spokesperson.

The CD-A is automation ready and can be easily integrated into production lines. The units 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 changing feature lets users automatically switch between two different schedules. The power supplies enable rapid fire between pulses for quick welding of adjacent locations.

Two models are available, both offering programmable squeeze time and hold time, polarity switching, internal limits and external communication. They are offered in 110-120VAC or 220-240VAC, single phase, 50/60 Hz. CD-A125A is a 125-Watt second unit and Model CD-A300A is a 300-Watt second unit. Built in the USA, the CD-A series is fully CE compliant. The CD-A series replaces Amada Miyachi America's ADP and DP series of capacitive power supplies.
