Welding Principle

As the drawing showsi the principle is as follow:
A pair of circumgyrating upper and lower welding rollers press the tinplate, by going through low voltage and high current to create heat and welding points on overlap. During the processing procedures, the copper wire acts as the media electrode, which can prevent polluting the welding rollers from the melting tinplate during process and take away the heat of the welding rollers.
Because melt joints between tinplate and copper wire are continuous, the quality of welding line is good and the upper and lower welding rollers do not need to be trimmed in quite a long time. Furthermore in order to make an even touch between copper wire and welded material, the round section copper wire is required to be pressed into flat section copper wire.


Main Feature:

1. Equipped with the most advanced human-computer-infer-face device, the whole operation can be made on the touch screen.
2. Equipped with the servo motor controlling system, different types of inverter waves are available to change to fit the different sheets.
