1. 1000Hz Medium Frequency DC welding machine is the most advanced welding power supply technology in welding industry. It is 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. Thus, the current is rectified in order to supply DC welding current.
2. Advantage: It helps to greatly reduce the energy of iron core material because the frequency of welding transformer is promoted from 50/60Hz of mains supply to 1000Hz.
3. Energy Saving: Besides, the commutation diode of subloop of transformer could transform the electric energy into DC power which is used to provide power for welding. 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.
1.Energy Saving: Compared with using AC power, it can help to reduce the consumption of electric energy. The same weight of transformer could output more energy. It can also be conveniently used with the large automatic welding clamp.
2. Reduce operation cost, including saving the energy of each spot welding and reducing the cycle of welding.
3. In a semi-automatic machine, one medium frequency transformer can replace many low frequency transformers which can help to reduce the parallel connection in secondary circuit.
4. Improve the power factor, reduce the production cost.
5. Reduce interference in secondary circuit which is in the large open area: the welding current is direct current. When there is induction or magnetic material in secondary winding, the welding will not be affected.
6. To make the power supply unit load balance: MF inverter spot/projection welder adopts the three-phase sources which can store energy.
7. More adaptable to the fluctuation of power grid and voltage drop: a part of the energy has been stored by inverter and been supplied to load. It replaces the way of power supply to load directly from the power grid.
8. More precise and fast control of current: Compare with low frequency system, it is able to analyze more parameters in a more precise way.
9. More reliable process: For most of the applied resistance welding metals, to use DC to weld will help to achieve better effect.
10. The technology of MF system is more traditional and reliable which can prevent the damage results from the breakdown of silicon controlled.
11. Reduce operation cost, including saving the energy of each spot welding and reducing the cycle of welding.
