High frequency welding machine price, Qingdao Tianrun High Frequency (certified), high frequency welder by day Run High Frequency Electric Co., Ltd. Qingdao. High frequency welding machine price, Qingdao Tianrun High Frequency (certified), high-frequency welding machine is High Frequency Electric Co., Ltd. Qingdao Tianrun (www.gaozhoubo.com.cn) this year launched a new upgrade, above pictures for reference only, please Dial telephone or pictures on this page, for the latest information, contact: Yan Lidong. 1, high-frequency and high-frequency current flow machine is made of circular or heating coil (usually with copper production) other shapes. Coil which produces instantaneous changes in the magnetic polarity of the beam, the metal is heated object is placed inside the coil, the magnetic flux will be heated through the entire object, the object being heated internal heating current in the opposite direction with high frequency welder , there will be corresponding large eddy currents. Because of the heated object memory in the resistance, it will generate a lot of Joule heat, so the rapid rise in their body temperature. All metallic materials to achieve the purpose of heating. 2, in the high frequency machine by a unique set of electronic circuits, external power input comes from 50Hz low frequency alternating current into alternating current of high frequency above 20000Hz; high-frequency current is applied to the coil inductance high frequency welder prices, using electromagnetic induction principle be converted into a high-frequency magnetic field and in magnetic field acting on the metal object; eddy current effect, generates a magnetic field proportional to the intensity of the induced current in the metal objects, the current flows in the metal objects, it will by means of internally inherent resistance value, the principle of the thermal effect generated by the current heat, this heat is generated directly in the interior of the body, so that this heating method, high-frequency welding supply speed, and high efficiency. If required, any metal material which can be melted in an instant. Moreover, it is the heating rate and temperature controlled. Conventional converter transformer at high frequencies, the central core will have localized hot spots. Therefore, in order to reduce the thermal effects, the conventional converter transformer when the working frequency increases, it is necessary to correspondingly reduce the magnetic flux density, increasing its volume. This makes it impossible to use it to do a power supply with high power density. Ideal for low output voltage converter, its step-down ratio is high. When using a conventional converter transformer is usually a high frequency welding equipment turns the output winding, it takes approximately 32 turn primary winding. Thus, the primary winding on the need multilayer arrangement, and thus between the large leakage inductance and winding capacitance, and serious adverse factors skin and proximity effects are present in the converter transformer.
