Problems solved by technology
[0002] The traditional cutting torch or welding torch is usually ignited by an external fire source, such as a lighter or a match, which may cause burns to the igniter when ignited, and when operating outdoors, due to strong wind large, hard to light
When working at heights, holding a torch in one hand and igniting the fire in the other will also cause the danger of people or objects falling, or when working in special places, it is impossible to bring a fire source such as a lighter into it, resulting in problems such as inability to work
[0003] In addition, the welding torch and the cutting torch are two different tools, and the two tools need to be purchased at the same time when working, which increases the cost of use and is more troublesome to use

Embodiment 2
[0025] Embodiment two, such as image 3 As shown, the torch body 1 can also include an oxygen valve 15, the oxygen valve 15 is located between the handle 11 and the oxygen pipe 13, the side wall of the oxygen valve 15 is integrally formed with a thickened part 16, and a supply wire can be opened in the thickened part 16 21 through the third perforation 17, one end of the third perforation 17 communicates with the end of the oxygen valve 15 close to the oxygen pipe 13, the other end of the third perforation 17 is used for the penetration of the wire 21 and is provided with a sealing device, the sealing device can seal the third The perforation 17 is sealed to prevent air leakage. In this way, the wire 21 passes through the fourth through hole 12 of the handle 11 and then passes through the third through hole 17 , crosses the oxygen valve 15 and enters into the oxygen tube 13 . And the oxygen pipe 13, the converging head 14 and the cutting nozzle 3 are all connected, therefore,...

The invention discloses a welding and cutting integrated gun capable of automatically igniting inside. The welding and cutting integrated gun comprises a cutting gun body, a cutting nozzle, and a direct-current discharge device arranged on the cutting gun body; the cutting nozzle comprises a nozzle core, and a nozzle cap sleeving the nozzle core; the nozzle core comprises a nozzle cap connecting thread, an insulation pipe and a discharge part connected in sequence; the discharge part comprises an electric conducting column and a discharge needle; one end of the electric conducting column is connected to the insulation pipe, and the other end is connected with one end of the discharge needle; the other end of the discharge needle is near an outlet of the nozzle cap; and eletrospark can be generated between the nozzle cap and the discharge part. The insulation pipe is provided for insulating the discharge part from the cutting gun body, and is used as one electrode of the direct-currentdischarge device; and the nozzle cap is used as the other electrode of the direct-current discharge device, so that the discharge part and the nozzle cap can be discharged; and meanwhile, the discharge part with a discharge needle structure is adopted, so that the cutting gun also achieves the functions of a welding gun to realize multiple functions.
Description
technical field [0001] The invention relates to a cutting torch and a welding torch, in particular to a multifunctional welding and cutting torch which has both the functions of the welding torch and the cutting torch and can automatically ignite inside. Background technique [0002] The traditional cutting torch or welding torch is usually ignited by an external fire source, such as a lighter or a match, which may cause burns to the igniter when ignited, and when operating outdoors, due to strong wind Big and hard to light. When working at high altitudes, holding a torch in one hand and igniting the fire in the other will also cause the danger of people or objects falling, or when working in special places, it is impossible to bring fire sources such as lighters into it, resulting in problems such as inability to work. [0003] In addition, the welding torch and the cutting torch are two different tools, and the two tools need to be purchased at the same time during work, ...
