OTC DAIHEN CPDP500 Digital Pulse Welder (Discontinued)

The CPDP500 was a digital pulse welder from OTC DAIHEN, featuring a unique digital control philosophy that provides instantaneous current waveform control for pulse welding, ensuring high performance of the welding process and system. With a stable arc, near 100% arc start rate, and low spatter, it was especially suitable for high-speed, high-quality welding with automated machinery. The built-in OTC welding expert system offers a rich database to meet diverse welding needs for materials such as mild steel, stainless steel, aluminum, galvanized steel, and copper. Digital display of current and voltage enhanced readability. Although discontinued, its technology has been carried forward in the successor model WB-P500.
