This Stationary Spot Welding Machine is a micro-computer controlled system designed for automated projection and spot welding applications, with a common use in fabricating components like automotive fuel tanks. Operating on a 380V/50Hz three-phase AC power supply, it utilizes three-phase rectifier and inverter technology along with a feedback control system to manage the welding heat cycle. This includes control over pre-press, weld, hold, and off times to meet specific welding requirements. The machine offers multi-process capability for materials such as low-carbon steel, stainless steel, and non-ferrous metals.
