Ready for Industry 4.0

The PRC7300 control facilitates the realization of horizontally and vertically networked welding systems according to connected industry: The dual-processor architecture for process control and communication allows especially high data transfer rates without affecting the welding process control. The fast information exchange with the higher-level controller can be easily realized using all common Ethernet protocols. All data are being centrally stored on a production server – this helps to reduce the number of required operating computers. An integrated web server allows wireless operation and diagnostics via smartphone and tablet PCs (WLAN). Welding PC and operating interface can be physically separated from the welding cell.
