Guangzhou Hao Jing Machinery Co., Ltd. Address: Guangzhou city, Guangdong Province, the new 6th Street Bamboo Town Tong Mei Guangzhou Tel: 18680635773 Shanghai Tel:.. 18616825856 SMD Series - frequency inverter is an advanced projection welder welding equipment. Wide range of applications, welding transformer small and large energy output. And because of its superior performance is the welding transformer upgrade from the current point of the city of 50 / 60Hz to 1000Hz, greatly reducing the weight of the core material, plus the transformer secondary circuit rectifier diode power into DC power supply to welding use. This can greatly improve the secondary loop inductance values, and thus the production costs to a minimum. Features: It is the current international advanced resistance welding products; welding stability has no intended ratio; low operating cost; balanced three-phase power input, power factor up to 95%; the secondary circuit is almost no induction energy loss; lower welding current and electrode pressure; more than double the battery life and reduce the electrode grinding time; significantly reduces installation cost of electricity and water installation, gas and other ancillary facilities; more accurate, faster, more comprehensive control and analysis of welding parameters; more short welding time and increase productivity; applies to most of the welding of metallic materials with better results. 1, three-phase AC inverter after entering through the rectifier circuit to become DC inverter circuit again organized by the IGBT power devices, becomes IF 1000HZ AC square wave output, after the step-down transformer is rectified into DC supply electrodes on the workpiece awakened welding. Frequency inverter controller with current feedback, pulse width modulation (PWM) way to get a stable current output. 2, compared with the normal frequency machine, frequency inverter DC welding output current form, with high control accuracy, output current stability, heat concentration, affect small inductance, high power factor, light welding transformer quality, low spatter and other advantages. IF inverter welder has become one of the necessary equipment to achieve high quality welding can weld many kinds of metal (steel, structural steel, galvanized steel, stainless steel, aluminum and different materials are combined thermal welding). 3, widely used, in particular, can better meet the automotive, appliance and other industries in the manufacturing process, well received by users.
