Study of welding machine connects to Ethernet based on embedded gateway

A network control system for welding machine based on Ethernet is described.With the development of technology of Ethernet,how to apply it to industry filed is a very important problem.The author first utilize the embedded gateway combining with MCU controlling system to fulfill the welding machine connection with Ethernet,which could integrate the welding machine with company information system based on ethernet and TCP/IP completely,and make it possible of network and information management during welding and remote diagnosis of welding machine faults.
