Capacitive Discharge Welders The CD-A is the latest and most advanced capacitive discharge welder that is automation-ready and features dual pulse output with control and monitoring of both pulses. • Built-in current monitor • Four pulse widths with fast rise times • Automatic polarity switching CD-A125A/300A only TYPICAL APPLICATIONS 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 CD-A125A/300A only Tack welding of carrier strip • Automatic polarity switching between pulses provides even heating between electrodes and increases electrode life CD-A125A/300A only • Up to four software selectable pulse widths increases the range of welding applications and improves process optimization • Efficient power electronics provide high repetition rates Conductive terminal attachment Resistance welding

Resistance welding RUN screen contains all information at a glance, with color coding. When Out of Limits occurs, box turns from green to red. Weld counter shows In Limits/Out of Limits percentage.
