This welding torch is a specialized welding torch specifically designed for the automatic TIG welding of small tubes and tube-to-tube sheets, and it is suitable for the automated welding of small tube-to-tube sheet types. It can weld various tube/tube-to-tube sheet joint types of materials such as carbon steel, stainless steel, and titanium alloy. Whether the tube protrudes, is flush with the tube sheet, or is retracted inside the tube sheet, it can be used for welding with or without wire filling, and the weld quality is highly consistent. The standard-equipped welding torch can be added with a trailing shield for the welding of metals with high protection requirements such as titanium alloy. It is used in conjunction with the XNLA400 digital program-controlled welding power source.

Application fields: Chemical machinery, food machinery, pharmaceutical machinery, power plants, military industry, various heat exchangers in the nuclear power industry, etc.
