[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This embodiment provides a lightweight welding torch, the structural schematic of which is shown below. Figures 1-4 As shown, the welding torch includes a gun body 1, a nozzle 2, a connecting pipe 4, and a handle 7. In this embodiment, the gun body 1 is the main structure of the entire welding torch, made of high-strength and lightweight aluminum alloy. While ensuring structural strength, it effectively reduces the overall weight of the welding torch, making it convenient for operators to hold and work for extended periods. A first connector 5 is provided at the nozzle head of the gun body 1. The first connector 5 has an internal thread structure, and the connecting pipe 4 is securely installed at the nozzle head of the gun body 1 through a threaded connection.

[0026] In a further embodiment, the other end of the connecting pipe 4 is connected to the nozzle 2 via a second connector 6. The second connector 6 also has an internal thread structure to ensure a firm and reliable connection between the nozzle 2 and the connecting pipe 4. A nozzle 3 is installed at the front end of the nozzle 2. The nozzle 3 is made of a special alloy material, possessing excellent wear resistance and high-temperature resistance, enabling it to adapt to the high-temperature and high-intensity wear environments generated under different welding processes, ensuring stable gas ejection and welding quality during the welding process.

[0027] In a further embodiment, a handle 7 is provided at the tail end of the gun body 1. The handle 7 is ergonomically designed, with a shape that conforms to the natural curve of the human hand, providing a comfortable grip experience for the operator and reducing hand fatigue during long-term work. A plug-in hole 13 is provided at the tail end of the handle 7 for connecting welding pipelines, such as pipelines for supplying welding gas and current. The plug-in hole 13 communicates with the inside of the nozzle 2, allowing welding gas to smoothly enter the nozzle 2 from the pipeline through the plug-in hole 13 and finally be ejected from the nozzle 3 for welding operations. A control switch and a switch button 8 are provided on the handle 7. The switch button 8 is located on the side of the handle 7 facing the nozzle 2, allowing the operator to easily operate it with their thumb while holding the welding gun. The control switch is located inside the handle 7 (not shown in the figure), and the switch button 8 is connected to the internal control switch and circuitry to control the connection between the plug-in hole 13 and the nozzle 2, thereby controlling the supply of welding gas and the start and stop of the welding process.

[0028] Furthermore, a protrusion 12 is provided on the side of the handle 7 away from the nozzle 2. The protrusion 12 has a triangular structure and is integrated with the gun body 1 and the handle 7. The side of the protrusion 12 facing the tail end of the handle 7 is perpendicular to the handle 7. This perpendicular structure can provide effective support for the connection between the handle 7 and the gun body 1, enhance the strength and stability of the connection, and prevent problems such as breakage or deformation during frequent use. In addition, when the user holds the handle, the protrusion 12 can block and limit the movement of the hand's web, making it easier to hold and operate. The beveled edge of the protrusion 12 is smoothly connected to the gun body 1, making the overall appearance of the welding gun more streamlined, reducing stress concentration, and improving the service life of the welding gun.

[0029] Furthermore, a boss 9 is provided on the side of the handle 7 facing the nozzle 2, located on the side of the protrusion 12 facing the tail end of the handle 7. The surface of the boss 9 is specially treated to have a certain friction, providing an additional force point for the operator when holding the welding gun, enhancing the stability of the grip and preventing the welding gun from slipping during operation. In addition, the end of the boss 9 facing the gun head of the gun body 1 extends upward and smoothly fits against the switch button 8. This design not only makes the welding gun more aesthetically pleasing but also avoids interference between the boss 9 and the switch button 8 during operation, while also facilitating cleaning and maintenance by the operator.

[0030] To further improve the comfort and safety of the welding torch, rounded chamfers are provided at the corners of both the torch body 1 and the handle 7 to prevent the sharp edges from scratching the operator's hands. A first pad 10, made of soft rubber material, is covered on the side of the handle 7 facing the nozzle 2, providing good elasticity and anti-slip properties. The first pad 10 extends to the torch body 1, providing comfortable support and cushioning for the operator's hands, reducing hand fatigue, and preventing direct contact between the hands and the torch body 1 and handle 7 to avoid burns. The switch button 8 and the boss 9 pass through the first pad 10, ensuring that the operator can operate the switch button 8 and the grip boss 9 normally.

[0031] Furthermore, a second pad 11, also made of rubber, is provided on the side of the handle 7 away from the nozzle 2, extending to cover the protrusion 12. The second pad 11 further enhances the comfort and anti-slip performance of the handle 7, providing the operator with a better grip experience.

[0032] Working principle:

[0033] In use, first insert the welding line into the insertion hole 13 at the end of the handle 7, ensuring a tight connection to prevent gas leakage. Then, the operator holds the handle 7 and places their index finger on the switch button 8. When welding is ready, the operator presses the switch button 8. This activates the internal circuitry, connecting the insertion hole 13 to the nozzle 2. Welding gas flows from the line through the insertion hole 13 into the nozzle 2 and is then ejected from the nozzle 3. Simultaneously, welding current is transmitted to the welding torch via the corresponding circuitry, generating an electric arc at the nozzle 3, melting the welding material and completing the welding operation.

[0034] During welding, the operator can enhance grip stability by holding the protrusion 9 on the handle 7, ensuring that the welding torch is accurately aligned with the welding area. After welding is completed, press the switch button 8 again to disconnect the connection between the insertion hole 13 and the nozzle 2, stopping the supply of welding gas and current, thus completing the welding operation.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
