Abstract
Description
Claims (1)
- 모재 절단중에는 전극은 모재로부터 떨어져 있으면서 노즐 말단은 모재와 접촉되며, 노즐 말단을 통해 전극으로부터 모재로 아아크가 통과하며 전극과 모재 사이의 간격을 아아크가 발생할 때의 처음 간격으로 부터 그 아아크로써 모재를 절단할 때의 다음 간격으로 변화시키는 플라즈마-아아크 절단방법으로써, 노즐은 전도성이며 모재 절단시에는 모재와 등전위 상태에 있으며, 위에서 언급한 처음 간격은 다음 간격보다 작으며, 아아크 발생시에는 노즐을 통해 아르곤 가스가 흐르고 모재 절단시에는 노즐을 통해 아르곤가스와 질소가스가 혼합되어 흐르며, 노즐과 모재와의 접촉에 의해 작동되는 릴레이 장치에 의해 전원으로 부터 전압이 걸려 아아크가 발생하게 되는 것을 특징으로 하는 플라즈마-아아크 절단방법.
