Plasma cutting gun is an efficient metal cutting equipment, its main role is to form a narrow slit on the metal material, in order to perform fast and effective cutting operations. Its working principle involves using compressed air as an ionizing medium and forming a high density plasma arc heat source through the compression action of the cutting gun nozzle. This heat source is able to melt the metal and then use high-speed air to blow away the melted metal, creating a slit.
Plasma cutting gun is suitable for cutting a variety of metal materials, including stainless steel, aluminum, copper, cast iron, carbon steel, etc. This cutting method is not only fast, narrow slit, flat incision, small heat-affected zone, low deformation of the workpiece, but also simple operation, with significant energy-saving effect.
In general, plasma cutting guns play an important role in manufacturing, metal structure manufacturing, maintenance and other industries, which can improve production efficiency and cutting quality.

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.
