PROBLEM TO BE SOLVED: To provide a gas cutting device capable of easily switching/adjusting intensity of preheating flame according to a situation with no possibility of accidental fire.;SOLUTION: The gas cutting device includes a cutting torch 11 which cuts a work 5, flow rate adjuster 20 which contains valve units 21-25 for adjusting flow rate of fuel gas, assisting oxygen, and cutting oxygen supplied to the cutting torch 11 to a different flow rate, and a control device 12 which, according to a cutting condition, selects a combination of valve units from among the plurality of valve units 21-25 which is suitable for the cutting condition, and drives the valve unit that supplies fuel gas or the like to the cutting torch 11. The flow rate adjuster 20 includes at least one ignition valve unit 21 in which flow rates of the fuel gas and the like are set to an ignition flow rate, and a plurality of flow rate changing valve units 22-25 adjusted to a flow rate of a different cutting condition respectively. The control device 12 is configured such that the ignition valve unit 21 is surely selected in all cutting conditions.;COPYRIGHT: (C)2013,JPO&INPIT
