Main Technical Parameters of this battery spot welder machine

1.1 Introduction of Mingda MD-500 professional spot welder machine 

MD series battery assembled welding power used Japan of most advanced of welding technology, is the present domestic advanced level of high performance precision storage DC resistance welding machine, designed for the production of high-end electric car batteries, electric vehicle batteries, power tool battery, Rover balance car batteries, 18650 battery pack combination, as well as cell phones, digital battery nickel-metal hydride and nickel cadmium batteries required to design, but also can be welded metal parts, LED lights, electronic components foot, capacitors and so on.

1.2  Advanced technology with MD-500 spot welder machine high precision

MD series precision resistance welding power supply is new power, which is used in Japan IGBT inverter technology, computer control technology and modern power electronics technology and development. The equipment principle diagram as shown in figure 1, due to the use of AC-DC-AC-DC inverter technology to achieve millisecond time control precision, control response and control precision is greatly improved; Spatter small, stable performance. The welding process is significantly improved; advanced technology also enables devices has advantages of small, energy efficient; use a microcontroller (MCU) and electronic technology to make the device with excellent features modern equipment, including digital control, monitoring , fault diagnosis and protection, data transmission, etc., equipment is fully functional, flexible, convenient. This kind of equipment is especially suitable for spot welding, spot welding alloys, spot copper, aluminum and other nonferrous materials, precision parts spot and high-quality products.

2.3 Main Technical Characteristics of this MD-500 spot welder machine:

1. DC output. Welding current is pulsating DC (and waviness small), no AC shortcomings zero-crossing is not continuous heating the workpiece, heat concentration, improve the welding thermal efficiency, it’s particularly suitable for nonferrous metal materials and some difficult welding materials, stable welding process, improved the welding quality significantly. Meanwhile, extended the electrode life.

2. High speed and high accuracy microprocessor (MCU) control, provides highly stable repeat welding, with current monitoring function.

3. Inverter with soft-switching technology, reduce the switching losses and electromagnetic interference.With the fault diagnosis  of abnormal currents, monitor overload, voltage overrun and alarm function.

4. Time wide range (0 - 9.9 ms), can be used for multi pulse application of complex welding process needs.

5. 10 parameters stored welding specification, convenience for the various welding varieties to use.

6. 128 * 64 Chinese LCD display, and display a variety of content at the same time, graphical display of the current operating state, friendly interface, welding pulse graphics display function to improve the convenience of debugging observation.

7. Welding speed: fast start and high-speed polarity switching reduces the temperature so that the welding surfaces are clean and beautiful.

8. Polarity switching: suppression of asymmetric effects to make two uniform welding strength and prolong the service life of the electrodes.

9. Imported IBGT module full bridge control welding discharge, welding quality and speed of non conventional energy storage welding can be compared.

10. Double-pulse reduces welding spatter, effectively improve the weld quality.

11. Data storage using EEPROM, no battery life issues, each time you boot back to previous welding procedures.

Welding voltage locking techniques to prevent the network voltage fluctuations affect the welding current.
