Features:

Tungsten Inert Gas Welding (TIG) or Gas Tungsten Arc Welding (GTAW) is an arc welding process where a non-consumable electrode is used for the welding. The weld area and electrode are protected from oxidation by the inert shielding gas which may be Argon or Helium. The filler metal is usually used in welding. The TIG welding equipment is used for thin sheets of stainless steel and nonferrous materials like Aluminium, magnesium and copper alloys. This is not useful in welding of Zinc alloy.The constant electric power supply produces arc which passed through the gas to vapors of the metal.

This welding process needs a trained welder as in this process of welding needs to use both hands very judicially. Here one hand is used to hold the torch to produce the arc and second hand used for the filler wire.
