The Flash Butt Welding Transformer is the core power component of flash butt welding machines. It efficiently converts high-voltage AC into the low-voltage, high-current power required for flash heating and upset welding of metal end faces. Designed for heavy-duty industrial use, it ensures a stable "flash + upset" process for high-strength joints.
