DESCRIPTION
Medium frequency inverter DC resistance control system: Refer to the following picture, the three-phase AC current has been rectified into DC. Then convert into medium frequency 1000Hz square wave and connected into primary of welding transformer through inverter circuit which is composed of IGBT. After the rectification through welding transformer, the current become DC with small pulsation and being supplied to electrode for welding. The inverter will adjust the duty cycle rate of IGBT according to the feedback of primary and secondary welding current so as to achieve constant current during welding process.

Compared with the normal AC controller, MF controller has the following advantages:
 
1. The current in secondary welding loop is DC. Dramatically reduce the impact to the welding current due to the inductive reactance in secondary loop when conducting welding to the work piece.
 
2. The weight of transformer is reduced greatly. It is light and convenient. The weight and size of the MF transformer is only 1/3 of the AC type transformer. Suitable for robot welding system.
 
3. Prolong the service life of electrode
 
4. Be able to weld material like aluminum, galvanized steel, etc. with good welding performance.
 
5. Especially suitable for three-layer plate welding, ultrathin material welding and precision welding.
 
6. Less splashes.
 
7. Increase control of current and welding quality.

FEATURE
 

1. Electrc Saving: It can help to reduce the consumption of electric energy compared with normal AC machine. The transformer of the same weight could output more energy. It can also be conveniently used with the large automatic welding clamp.

 

2. For 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. Reduce the production cost by improving power factor.

 

4. 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.

 

5. More reliable process: For most of the applied resistance welding metals, to use DC to weld will help to achieve better effect.

 

6. 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.

 

7. More precise and fast control of current: Compare with low frequency system, it is able to analyze more parameters in a more precise way.

 

8. To make the power supply unit load balance: MF inverter spot/projection welder adopts the three-phase sources which can store energy.

 

9. The technology of MF system is more traditional and reliable which can prevent the damage results from the breakdown of silicon controlled.

 

10. Reduce operation cost, including saving the energy of each spot welding and reducing the cycle of welding.
