The invention relates to the field of gas cutting equipment, and provides a cutting torch. The cutting torch comprises a cutting nozzle, an oxygen injection pipe, a mixed gas pipe and a handle, wherein an inlet end of the oxygen injection pipe and the inlet end of the mixed gas pipe are connected to the handle, an outlet end of the oxygen injection pipe and the outlet end of the mixed gas pipe are connected with the cutting nozzle; and an electronic igniter is arranged on the handle, and the tail end of a discharging lead wire on the electronic igniter extends to one side of the outlet of the cutting nozzle. According to the cutting torch, the electronic igniter is arranged, and the tail end of the discharging lead wire of the electronic igniter extends to the outlet of the cutting nozzle, therefore fuel gas sprayed out of the cutting nozzle can be directly ignited by starting the electronic igniter on the handle, so that the cutting operation is carried out, the cutting torch is simple and convenient in operation, the safety and reliability are achieved, scalding accidents caused by the situation that protective gloves for welders need to be removed when the cutting torch is manually ignited is effectively avoided.
Description
technical field [0001] The invention relates to the field of gas cutting equipment, in particular to a cutting torch. Background technique [0002] As a gas cutting device, the cutting torch is widely used in cutting metal workpieces. The function of the cutting torch is to mix oxygen and acetylene in proportion to form a preheating flame, and spray high-pressure pure oxygen onto the workpiece to be cut, so that the metal to be cut is burned in the oxygen jet, and the oxygen jet burns the slag generated by combustion (Oxide) is blown away, thereby forming a kerf in the cut metal. [0003] Cutting torches are divided into jet-suction and isobaric types according to the mixing method of oxygen and acetylene in the preheating flame, among which jet-suction cutting torches are most commonly used. [0004] When the traditional injection-suction cutting torch is in use, the operator needs to take off the welder's protective gloves and use a lighter to ignite the gas ejected from...
