1, the welding power source, its output power and welding characteristics match should be used in Cast Iron Welding Wire  processes, and equipped with a connection to the host controller interface.
2, the wire feeder control and speed control system, higher precision wire feeder wire feed speed control, the control circuit should be added to the tachometer feedback
Welding head moving mechanism, the composition of the welding head, welding head support frame mounted extension units, to precision welding head mechanism, the drive system should be used servo motor with encoder
 4 weldment mobile or deflection mechanism, such as Welding Electrode Materials, head and tail frame flip the rotating platform and positioner machines and other precision-mobile mechanism with servo motor drive
5 weldment clamping mechanism
6, the main controller, also known as the system controller, mainly for the linkage of the various components of the control of welding procedures for control, welding parameter settings, adjust and display. When necessary, can be extended to control functions such as fault diagnosis and man-machine dialogue.
 7, computer software, welding equipment commonly used in computer software: programming software, functional software process methods, software and expert systems, etc.
8, the orientation of the welding head tracker, the arc voltage automatic controller, torch yaw and monitoring system
9 auxiliary devices, such as wire feed system, circulating water system, the flux recovery and delivery devices, wire brackets, cables, hoses and trailers
