Product Description MF170-3G Galvanized Sheet Welding Transformer( Prices are for reference only, please contact the salesperson for specific prices.)Product DescriptionApplication For all kinds of intermediate frequency, power frequency resistance welding machine.Such as automobile welding clamp,seam welding machine, mesh welding machine, and so on.Brief introduction Medium-frequency (MF) transformers are a result of recent advances in resistance welding technology. They are powered by a transistor inverter, supplying square wave AC 500 V @ 1000 Hz which is converted by the MF transformer to a low voltage high current AC.This low voltage AC current is rectified to DC by a diode block built into the transformer.The higher operating frequency of an MF system allows efficient energy conversion using a smaller and lighter transformer.Other benefits with MF transformers used in portable and robotic welding guns are:The reactance of the welding loop only limits the upslope and downslope of the welding current.While the peak welding current is limited only by the welding loop's resistance. The net result is again a smaller transformer, especially when welding with the large throat, high-impedance guns.MF welding is less demanding on the plant power system.The MF inverter draws a balanced line current from all 3 phases and operates at a high power factor (0.9).With MF transformers the peak welding current almost equals its RMS value, which helps to obtain quality welds with no splash and constant strength even at lower pressure.The high frequency permits much faster - 1000 times per second - process control, which again results in better weld quality.Product Parameters TYPE MF170-3Gprimary nominal voltageV500nominal power at 20%EDkVA170nominal power at 50%EDkVA105nominal power at 100%EDkVA75secondary voltageV9permanent DC current 100%A8500Short circuit currentKA38turns ratioN1 / N255:1weightkg20temperatur switch 2 x 150 °C, 1 x 70 °C Temperature switchinsulation class F (155 °C)Current measuring coil 150mV/KA ±3%Sizemm160X130X256cooling water < 30°CL/ min8pressure drop Mpa<0.2 Company CertificateFactory environment display: Packaging & Shipping
