Automatic Medium Frequency Power DC Spot Welding Machine Aluminum Products
DESCRIPTION
MF DC Inverter Spot Welder is a set of 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 so the current is rectified in order to supply DC welding current. 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. 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.

FEATURE
1. Energy Saving: Compare with using low frequency, it can help to reduce the consumption of electric energy. The transformer of the same weight could output more energy. It can also be conveniently used with the large automatic welding clamp.
2. 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.
3. Improve the power factor, reduce the production cost.
4. 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.
5. To make the power supply unit load balance: MF inverter projection welder adopts the three-phase sources which can store energy.
