A torch for TIG(Tungsten Inert Gas) welding is provided to prevent the argon gas supply pipe and the power supply pipe from melting due to the heat delivered from the head. A TIG welding torch(100) comprises a head(10), a main body(20), and a holder(30). The main body includes an argon gas supply pipe(22) and a power supply pipe(21) to which a hose(26) and a power cable(25) are connected. The argon gas supply pipe supplies argon gas through a connector(23), and the power supply pipe supplies power through the power cable. The holder has ventilation holes(31) on the bottom circumference. The argon gas and power supply pipes extend to the ventilation holes.
