" The metal ARD welding of inert gas " was initially proposed by U.S.A. N. Davis R. T. Terordg In 1956.

The completed name of the argon welding is called as " Inter Gas Tungsten ARC Welding ,Abbreviation GTAW”,Call too " Tungsten Inter Gas Arc Welding ,Abbreviation TIG .  It’s a kind of welding method which use the tungsten as the electrode and the inter gas of argon , helium ,etc. as the protection.

Will be known as " the argon welding " in Taiwan, because mostly use the argon to be as the protection.

The older argon welder is big and cumbersome ,The function has only a handy weld. Due to the market demand in recent years, the argon welding machine is stressed more and more to be lightly and well , our company increase the technology  and improve the machine by the most advanced inverter to let the machine as light as possible, we extend the types of TIG200S, TIG200N , TIG250, TIG300A TIG300AP, TIG 200AC/DC TIG315AC/DC . It is light with the great power, there are many functions, it is simple and easy to maintain, durable, all these are function focal points that our company often require to the argon welder .
