Welding can be both a profitable and fun hobby. There are different methods used and different equipment for each method. One of the favorites of seasoned welders is called TIG welding.
TIG is short for Tungsten Inert Gas. A tungsten electrode is used to deliver current and an inert gas is used to protect and cool the weld puddle.
There are other who may say that TIG welding can be slow and they may be right. But this welding method is also very precise which make it perfect for welding small spots and other scenarios that require precision in both size and location.
