Hwashi Single-phase /Three-phase Coil Ressort Spot Welding Machine

? Hwashi Single-phase /Three-phase Coil Ressort Spot Welding Machine ?1. MF Inverter Spot Welder?is an advanced welding equipment. The three-phase power supply, through rectified by a special inverter, is converted into 1000Hz AC voltage and then is transmitted to a medium frequency transformer then the current is rectified in order to supply DC welding current. 2.?The advantage is that it helps to greatly reduce the?energy of iron core material, as the frequency of welding transformer is promoted from 50/60Hz of mains supply to 1000Hz. Besides, the commutation diode of subloop of transformer could transform the electric energy into DC power which is used to provide power for welding. 3. Under such circumstance, the inductance coefficient of subloop could be improved dramatically and the production cost could be minimized because the inductance coefficient is an important factor that results in energy loss but could almost be ignored in DC welding circuit.
