| Abstract: | The operation principle of switch type field-effect tube DC &. pulse are welding power source and the principle of getting pulse out-put are introduced in this peper. The pulse giving circuit with vibration frequency and duty cycle adjustable is put forward. After testing the electric characteristics and TIG welding in this new machine, it is result that this machine has good operating and control characteristics and high effeciency. This power source with electric control has bright future. |
