Argon arc welding gun is a tool that utilizes argon arc welding technology, which effectively insulates the welding area from air contact and prevents oxidation of the welding area by using argon as a shielding gas. This welding method has been widely used in the industrial field because of its high efficiency and controllability.

The working principle of the argon arc welding gun involves the characteristics of the tungsten needle as the heating end rather than the melting electrode. The design requirements for the argon arc welding gun include a good flow state and a certain stiffness of the protective air flow to ensure reliable protection effect. In various types of nozzles, the nozzle with equal section has the largest effective protection area of airflow, so it is also the most widely used.

In summary, argon arc welding gun, as an important welding tool, plays an indispensable role in industrial production. Its design and use need to take into account the protection of air flow to ensure the quality of welding.
