Description

Technical Field

[0001] This utility model relates to the field of argon welding gun technology, specifically to a quick-adjustment argon welding gun head. Background Technology

[0002] An argon arc welding torch is a tool used for argon arc welding. It typically consists of the following components: a handle for holding the torch; a cable connecting the torch to a power source; an electrode head containing a tungsten electrode that generates the electric arc; and a gas nozzle for spraying the shielding argon gas. Argon arc welding torches are suitable for various metallic materials, such as stainless steel, aluminum alloys, copper and its alloys, low-alloy steel, and heat-resistant steel, providing high-quality welds and reducing defects such as oxidation, porosity, and cracks. Using an argon arc welding torch allows one person to operate multiple devices simultaneously, simplifying operation and eliminating the need for a professional welder. Proper use and protection of the argon arc welding torch are crucial for ensuring weld quality and safety.

[0003] A proper height between the tungsten needle and the workpiece is essential for good welding quality. After welding, the surface of the tungsten needle may be contaminated and requires grinding. Grinding alters the optimal welding distance, necessitating adjustment to restore the needle height to the optimal welding distance. Currently used tungsten needle positioners are complex in structure and cumbersome in operation. Welders require a significant amount of time and a high level of skill to position the tungsten needle, causing inconvenience and reducing work efficiency. Therefore, we propose a quick-adjusting argon welding torch head. Utility Model Content
