[Ito YT250AW] power electric welding machine argon arc welding machine



can be used for conveying water, gas, oil, petroleum, chemical, essential for power generation, irrigation, transportation, machinery and other industrial materials. Among them, the oil industry is the largest user of steel pipe. Petroleum pipelines (mainly oil and gas pipelines) account for about 50% of the steel pipe production in some developed countries in the petroleum industry and the steel industry. Steel pipe is also an important international industrial supplies. At the same time, the steel pipe is also a good building materials for industrial plants, bridges, harbors and other buildings, and some countries use it as a pile. With steel pipe to replace concrete reinforcement, can save about 60% of steel.






power welder introduces the project status, technical requirements, and the main work of this project in the part of introduction. On the basis of the completion of the project related theory, discusses the development of power electronic technology, such as square wave voltage inverter, power frequency square wave output voltage regulator mode selection and key circuit design is made; according to the requirement of project implementation and project technology, the protection of the main power circuit part of the main circuit and the inverter power supply topology design, circuit principle, power switch parameter calculation and selection of power switch, the switch device in careful detail; in the control circuit, briefly discusses the design of the PWM pulse generating circuit and principle of PWM pulse control circuit and the key circuit chip. Finally, this paper introduces the field debugging process of the whole inverter, gives the measured waveform, and analyses and discusses the measured waveform. The new subject of self generating electric welding machine
