Description

Technical Field

[0001] The utility model relates to the technical field of welding, is easy to install and use, and in particular relates to a portable argon arc welding gun with adjustable welding parameters. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Welding is a major technical point in the construction of chemical plants. During the installation and welding of equipment and pipelines in chemical plants, due to different welding material thicknesses, pipe diameters, positions and other issues, it is necessary to change the welding process parameters at any time to adjust the applied welding current. This is especially inconvenient when welding workpieces at high altitude or remotely, and when welding small-diameter, thin-walled pipes. Welding areas at construction sites are often distributed across various locations, and on-site distribution boxes are located and managed on the ground. In the prior art, welding at height or remotely requires different welding parameters, making it difficult for one person to complete the welding task. Therefore, someone needs to be available to adjust the welding parameters at all times, which brings many inconveniences. For example, patent application number 201910255350.5, entitled "A Manual-Automatic Intelligent Welding Machine for Electric and TIG Welding with Display," discloses an LED touchscreen that can display and adjust parameters. However, the touchscreen is located on the main body of the machine, which is mounted on a mobile mechanism and is managed on the ground. This makes it impossible for one person to complete the welding task during height or remote welding. When the welding operator needs to change the welding process parameters, they need to manually adjust the welding parameters on the welding machine. Furthermore, the welding gun in the prior art is a one-piece structure. Since the TIG welding gun is a consumable part, it is easily bumped during transportation and storage due to its large overall size, which can damage the TIG welding gun and affect the welding progress. Utility Model Content

[0004] In order to overcome the deficiencies of the above-mentioned prior art, the utility model provides a portable argon arc welding gun with adjustable welding parameters. The parameters can be remotely adjusted through the argon arc welding gun according to the thickness of the welding material, pipe diameter, position and other workpiece sizes. It is suitable for high-altitude or remote welding, flexible and convenient to use on site, easy to disassemble and replace, ensuring welding quality, saving time and effort. One welder can complete the welding work, improving production efficiency, and it can be easily stored and easy to carry and install.

[0005] To achieve the above objectives, the embodiments of the present invention provide the following technical solutions:
