1) A of welding fixing blocks can realize the installation and fixation of pen-type electric soldering irons; 2) Using profile brackets, it has high mechanical strength, simple structure and easy assembly; 3) Because the main part is made of aluminum profiles, it is strong and , low in cost, and reduces later maintenance costs. The appearance can also be modified and decorated according to user needs; 4) The tool uses a tension spring to automatically reset the electric iron, which plays a protective role and is simple, practical and easy to replace; 5) The structure uses 4 sets of pulleys to that the soldering iron can be pressed down smoothly and without jamming during work; The upper and lower limits are used in the structure, which can be adjusted according to the working conditions to that the soldering iron presses down the limit during operation and does not damage the workpiece. Name: Heat Set Insert Press Heat Insert Tool Scope of application: Suitable for pen-type soldering irons (for example: 877, Arrizo arz-c, Huanghua LT66, TS100/101, Pinecil, etc.), often used for hot-melt copper nuts printed on 3D printers or on plastics upper implant nut Main components: aluminum profiles, fasteners, springs, pulleys, 3D printing parts Product printout link: 6360996 https://.thingiverse.com/thing:6360996/edit Notes: Different countries have different voltages, so you need to choose the corresponding voltage and soldering iron model, as well as the 3D model of the soldering iron fixings. When the electric soldering iron is powered, it generates high temperatures and is easy to burn, so it is dangerous. Please pay attention to safety when using it. Plug Type :EU Plug,it applies to Indonesia, Germany, France, Spain, Italy and so on. Voltage: AC 220V Colour:Black Material:plastic+metal Package Contents: 1 x Hot melt nut inlay press kit 1 x soldering iron
