PURPOSE: A gas cutter is provided in which tip is easily replaced even when an induction member is fused onto cutting oxygen channel of a cutting oxygen supply pipe, and which smoothly supplies gas and buffers or blocks backfire of gas at the same time by installing a buffer induction member inside a gas control member. CONSTITUTION: In a gas cutter in which control members(6'',7'') of cutting oxygen pipe(6) and fuel gas pipe(7) coupled by fastening nuts(6''',7'''') are installed in front of a cutter handle(10) to which a cutting oxygen pipe fitting(9) and a fuel gas pipe fitting(9') comprising a fuel gas gate interposed between the fuel gas pipe fitting(9') and the cutter handle(10) are connected, and a head body(1) is installed at the front end of the cutting oxygen pipe(6) and fuel gas pipe(7), the gas cutter is characterized in that the tip is integrally coupled to the head body(1) by a fastening nut(8) with a flange part formed on the upper part of a tip(3) being contacted with the lower part of a screw part of the head body(1) in such a way that a cutting oxygen supply way is formed in the central part inside an empty space of the tip(3), a locking part of an induction member on the outer circumferential surface of which a plurality of vortex guiding paths are formed is lockingly inserted into the tip(3), a connection part formed on the upper part of the induction member is lockingly inserted into a cutting oxygen channel inside the head body(1) with a heat resistant packing being interposed between the connection part and the cutting oxygen channel, and a crimped gas supply way is formed at the lower end inlet part of the induction member.
