There are 3 popular TIG wires used in plug building. They are all stainless steel alloys; 304, 308, 316. 304 being the softest and easiest to work. Some are labeled with an "L" this signafies that the wire is annealed.
TIG is a welding process know as "Tungsten Inert Gas" The melt flow is blanketed with an inert gas to allow a pure flow. The TIG process does not require any flux or melt enhansers thus the plain wire.
