DESCRIPTION of 100KVA PLC Controlled Three-Phase Medium Frequency DC Spot Welding Machine For Silver Contact And Copper Sheet
Medium frequency inverter DC resistance control system: Refer to the following picture, the three-phase AC current has been rectified into DC.

1.High quality,high efficiency.98% power factor,three-phase input load balancing,the impact on the

user grid has been greatly reduced, DC input current, smooth,inductance is zero. 1000HZ working frequency, time control precision is 1MS

2.High strength body structure, good rigidity, direct pressurizing mechanism, linear bearings used in the guiding structure enable good mobility

3.Adopt high-speed microprocessors,use intelligent optimal calculation method, LCD interface,can save 101sets welding schedule numbers. There are functions of switch display in both Chinese and English,provide external BCD call interface,system fault diagnosis alarm automatically.etc

4.Specially suitable for welding higher conductive rate of material (such as aluminum,copper,silver and so on) and much more thicker workpiece,widely used in automobile,aerospace and other high request products and industry.

Medium Frequency Welding System Composition
Welding Controller, transformer, and welding work piece.
Welding controller includes the controlled rectifier, energy storage part,IGBT,power driving and central control part.

Intelligent welding control system

Intelligent Touch Screen Controller
Input and read welding parameters.

Raw materials made to standard

Thicker Copper Plate or Copper Belt To ensure stable conductivity in welding

Custom processing of electrodes

Customized Electrodes which will be suitable for Welding material like steel,

aluminium, silver, stainless Steel, and nickel steel.

Shape structure and welding method

Design the right machine shape and mold according tothe welding product.

Compared with the normal AC controller, MF controller has the following advantages
1. The current in secondary welding loop is DC.
2. The weight of transformer is reduced greatly. It is light and convenient.
3. Prolong the service life of electrode.
4. Be able to weld material like aluminum, galvanized steel, etc.
5. Less splashes.
6. Increase control of current and welding quality.
