Abstract

본 발명은, 플라스마토오치로서 작동가스를 균일하며 또한 강력한 와류로 하여 플라스마제트의 출력을 보다 안전하게 함과 동시에, 양호한 절단품질이 얻어지며 소모부품 등의 수명을 향상할 수 있다. 이때문에, 작동가스(G)를 분사하는 분사구(3)의 위치는 이 각 분사구(3)를 포함하여 이루어지는 선회기(50)의 횡단면(2A)에 있어서, 와류실 직경(D)과 분사구멍(3a)의 축선(3b)의 투영선(3c)에 평행하게 되는 와류실 직경(D)의 접선(2b)으로부터 분사구(3)의 접선(2b)측의 측단(2c)까지의 최단거리(d)와의 관계가 0＜d/D
