Abstract

This application discloses an electrical discharge welding repair machine with good air-cooling effect, including a main unit housing, a welding torch, and a cooling assembly. The cooling assembly includes a centrifugal fan, a first air duct, and a second air duct. The centrifugal fan is placed at the bottom of the main unit housing. The first air duct connects the centrifugal fan to the interior of the main unit housing, and the second air duct connects the first air duct to the welding torch. The second air duct is arranged around the surface of the welding torch. This cooling method cools the electrical discharge welding repair machine. Furthermore, the arrangement of the first and second air ducts allows for separate cooling of the main unit housing and the welding torch. The air-cooling method not only reduces costs and footprint but also eliminates the need for refrigerant structures, reducing weight and ensuring normal operation of the welding torch. The second air duct, arranged around the surface of the welding torch, increases the contact area with the welding torch and facilitates disassembly and assembly, making it convenient to use.
