Welding head fixer for electronic fusing soldering welder

A welding head fixer for an electronic fusing soldering welder is provided. The front end surface of a welding head clamp is a notch, and the positive contour line of the notch can be various curves. Thus, when users weld work pieces, the line of sight can pass through the notch and can not be shielded, and the users can see the work pieces clearly. Holding screws passing through the right clamp splice of a left clamp splice adopt insulated screws to save other insulation isolation components. The screw head is positioned at the inner side of the left clamp splice. An insulation guide way is respectively placed at the front and back ends of the clamp splices, and the two insulation guide ways can adopt a cylindrical pin structure. When the users want to loosen and tighten the clamp splices, the users just need to operate the tight mechanism of the welding head and the clamp splices. The aim of the utility model is to provide an electronic fusing soldering welder with the following advantages: the line of sight can not be shielded, high light is used to illumine, the users can see the work pieces clearly, the insulation isolation components of the holding screws of the clamp splices are not needed to use, and the users just need to operate the tight mechanism in the process for dismantling and installing the left clamp splice.
