Plasma and TIG welder are the two most commonly preferred welders with respect to precision fusion in the welding industry. Firstly both TIG and Plasma welders were developed with a hope and aim to make welding possible on a variety of metals and their respective alloys. But with passage of time and mind-blowing development of technology and sciences, they have improved to be capable of providing accurate welds. They are so accurate, so much so that the processes are greatly used in miniature welding processes and applications.

In the Tungsten Inert Gas (TIG) welder, electric arc between the tungsten electrode and the point of contact of the metal to be welded is produces. The arc is kick started when high voltage is supplied to the electrode. This heat that is being produced will heat up the metal and allow fusing to be take place. Even a plasma cutter uses a tungsten electrode.
