TIG welding machine, or gas tungsten arc welding (GTAW) arc welding machine, is a metal welding device that uses a heat source provided by an arc formed between the electrode and the electrode. does not melt and puddle. The arc zone is protected by an inert gas environment (Argon) to prevent the harmful effects of oxygen and nitrogen in the air. The commonly used non-melting electrode is tungsten, so this welding method in English is called TIG (Tungsten Inert Gas) welding. TIG welding machine is used when welding small and thin parts, especially preferred when welding stainless steel. Multi-function electronic tig welding machine can weld all kinds of aluminum, stainless steel, …
