50KVA~300KVA Intermediate Frequency DC Spot Welder

 

 

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.
