Heat Treatment Units WELDOTHERM®- VAS with DIGIT 700 WELDOTHERM® manufactures a standard program of fully automatic program controlled heat treatment units of all output ratings. joint can be heat treated as well as a large vessel joint or any other workpiece. To connect a heating element to a wrong voltage is therefore almost impossible. Within these output ratings, optimized according to the respective application, any number of control circuits, fully independent from each other, are available. WELDOTHERM® heat treatment units are equipped with safety facilities for personnel and...

Heat Treatment Units The STANDARD EUROPA series was developed to meet the needs of most customers who want to do preheating and annealing jobs with high precision but without having the requirements of complex program profiles. These demands led to the heat treatment unit STANDARD EUROPA which unite the familiar WELDOTHERM® quality with a unique price-performance ratio. By standard, 6 or 12 fully automatic program controller TC 80 control the STANDARD EUROPA unit, as an option the TC 1000 touch screen control system is available. Both program controls are very easy to program and...

Heat Treatment Units The induction heat treatment unit VAI works according to the principle of inductive heating in the medium frequency range from 4 to 10 kHz. With this type of heat input, the heating energy is transferred to the workpiece by means of an inductor. The heat is generated inside the component, i.e. the workpiece is heated from the inside. Areas of application for the induction machine VAI are processes which involve a fast and even heating of metal materials. It is for instance possible to preheat welding joints within seconds. Thanks to the use of the rigid or...
