Tap-type welding machine is a relying on the winding to increase the leakage resistance, in order to get steep drop AC hand arc welding power. It has excellent welding performance, simple structure, easy to manufacture and maintain, etc., suitable for manufacturing small capacity light welder. This paper systematically introduces the basic principle of this kind of welding machine, discusses the principles and measures of how to deal with various contradictions in the design, discusses the selection and calculation method of the main technical parameters in detail, and analyzes the calculation of the structure parameters-leakage reactance, Made a detailed analysis and appropriate simplification. The formulas and data listed in the text have all been verified through a certain range of practice with certain reliability and practical reference value. In order to make readers have a brief understanding of the full text, will now be published in a single directory for a brief introduction: First, the basic principles 1. Enhanced magnetic flux leakage welder 2. Winding division and the division than two, light welding machine Design principles and characteristics of the three structural design of the two issues 1 core section and the basic determination of the number of turns 2 to determine the gear ratio four leakage leakage - the structural parameters of five conclusions
