TIG welding allows you to connect elements without the need for any additional material. Instead, the welding groove is melted down. However, when a complementary material is used, it is placed by hand. It is a different technique than, for example, MIG MAG, where such material is added using a welding gun. The handle in the TIG method has a different structure, and the binder is most often a wire or a rod, the length of which is a metre and has an appropriate diameter.
Welding of stainless steel, aluminium or other metals with the TIG technique is carried out with the use of chemically inert protective gas. Usually, it is either argon or helium that flows from the electrode holder. The gas protects the weld and the electrode against the oxidation process and does not interfere with the welding process itself.
