Abstract
With the machinery required to improve the welding, welding equipment and technology have developed rapidly accordingly. There are more and more welding applications, toward high-quality, technology, and a variety of directions. In this demand, the welding process equipment has been the development trend of its development in the following areas:
   (1) more and plete variety of equipment.
   (2) Equipment and system gradually raise the grade.
   (3) To the fully automated, efficient direction.
  The design of the solution of practical problems from the point of view, the existing ponent of welding machines to conduct in-depth research on the various parts of the principle, structure, movement, function and overall control of an in-depth analysis. The machine draws on the merits of the existing equipment and there is no lack of theoretical innovation. To make full use of the mechanical-electrical integration technologies, making the machine more practical. The design pleted the following major tasks:
1, Designed with the motor control table movement at the same time in the labor-saving machinery greatly increased the degree of automation.
   2, to achieve speed of transmission regulation agencies by use of stepper motors, which regulate the speed of welding. At the same time, the welding speed LED d
