Provided in an embodiment of the present invention is a gas cutting device, which can reduce working time and increase productivity. To this end, the gas cutting device comprises a base unit, a gantry unit, a head unit, a first cutting unit, a second cutting unit, a rectilinear driving unit, a first sensing unit and a control unit. Here, the base unit comprises a bed on which a cutting material is placed, and a pair of rails provided in a longitudinal direction of the bed at both sides of the bed. The gantry unit has both end portions individually coupled to the rails, and is disposed in a width direction of the bed so as to be moved along the rails at the upper side of a cutting material. The head unit is provided at the gantry unit and is moved in a longitudinal direction of the gantry unit. The first cutting unit is provided at the head unit and has a first torch which cuts the cutting material when the gantry unit is moved along the rails such that the cutting material may have a predetermined width. A second cutting unit is provided at the head unit, and has a second torch which cuts scrap produced when the first torch cuts the cutting material. A rectilinear unit is provided at the head unit, and has one end portion connected to the second torch, thereby making a reciprocating rectilinear movement in the width direction of the bed while moving the second torch such that the second torch may cut the scrap in a predetermined length. A first sensing unit is provided at one end portion of the rectilinear driving unit, has a uniform relative location with respect to the second torch, and detects the scrap at the lower portion. When the first sensing unit detects the scrap at the lower portion, a control unit allows the second torch to spray flame and gas, and operates the rectilinear driving unit. 본 발명의 일실시예는 작업 시간을 단축하고, 생산성을 향상시킬 수 있는 가스절단장치를 제공한다. 여기서, 가스절단장치는 베이스부, 갠트리부, 헤드부, 제1절단부, 제2절단부, 직선구동부, 제1센싱부 그리고 제어부를 포함한다. 베이스부는 절단재가 놓이는 베드와, 베드의 양측에 베드의 길이방향으로 구비되는 한 쌍의 레일을 가진다. 갠트리부는 양단부가 각각 레일에 결합되고, 베드의 폭방향으로 마련되어 절단재의 상측에서 레일을 따라 이동한다. 헤드부는 갠트리부에 구비되고, 갠트리부의 길이방향을 따라 이동한다. 제1절단부는 헤드부에 구비되고, 절단재가 미리 설정된 폭을 가지도록 갠트리부가 레일을 따라 이동 시에 절단재를 잘라내는 제1토치를 가진다. 제2절단부는 헤드부에 구비되고, 제1토치가 절단재를 잘라냄에 따라 생성되는 스크랩을 잘라내는 제2토치를 가진다. 직선구동부는 헤드부에 구비되고, 일단부는 제2토치와 연결되며, 베드의 폭방향을 따라 왕복 직선 이동하면서 제2토치가 스크랩을 미리 정해진 길이로 잘라내도록 제2토치를 이동시킨다. 제1센싱부는 직선구동부의 일단부에 구비되고, 제2토치와 일정한 상대 위치를 가지며, 하측에 스크랩을 감지한다. 제어부는 제1센싱부가 하측에서 스크랩을 감지하면, 제2토치에서 화염 및 가스가 분사되도록 하고, 직선구동부를 구동시킨다.
