By integrating the transformer and cooling system into a single shell and merging them into one without occupying any ground area, heating tasks are provided with more flexibility. The high coupling coefficient of the LH3B third-generation transformer is used to reduce losses with less electric heating equipment. Smart Rega: Smart Rega: Smart Rega. Smart Rega. Smart Rega Better heating effect for complex workpieces. Handheld brazing can be achieved for complex and difficult to access workpieces or workshop positions. It is safe and environmentally friendly. It has no flames, gases, and thermal radiation, providing operators with a more comfortable and environmentally friendly working environment
