Medium frequency inversion constant current welding power source is mainly made up of transformer, controller, inverter, power drive,rectifier parts, capacitor plates, IGBT as well as the central control components. Medium frequency inversion constant current welding power source is a set of advanced welding equipment and is widely used. The size of welding transformer is small but the output of energy is large. The feature is the original input voltage 50/60HZ cn be rectified to 1000HZ and the rectified diode of transformer secondary circuit can transform the power into constant current power source so that the secondary circuit reactance coefficients can be greatly improved (it is an important factor in causing the loss of energy before improvement), and it is almost taken into consideration in constant current welding circuit, almost, and thus production costs are minimized. Compared with conventional welding power source, it has the following

 

*Save Electricity

*Improve the power factor and reduce production costs In the secondary circuit with large opening area,interference can be reduced and welding current is constant current. When the secondary winding has inductive materials (with magnetic property), it will not affect the welding

*Make a balance of the loading of power supply device ,medium frequency inversion constant current welding power source uses three-phase power and stores energy

*The adaptability to the fluctuation in the grid and the pressure drop is strengthened. Some are stored by dc-to-ac inverter to supply loading and replace the way of supplying power and loading form the grid

*More accurate, rapid and accurate analysis to parame-ters

*Damage of oblique wave interference caused by SCR systems can be avoided
