arc. The distance between the work piece and the Tungsten is governed by the
amount of welding current in use and the Tungsten diameter, as for MMA welding.
Pulse DC TIG this is the same process as DC TIG except the welding current is not at a
constant level. The welding current rises to a peak and falls to the basic level, this ena-
bles the welding of thing materials with a reduced risk of melting holes.
AC TIG is used for the welding of aluminium and its alloys, these metals have a hard
heat resistant oxide layer on the surface, the oxide layer needs to be removed in or-
der to produce a strong weld.
During welding the polarity of the torch and work are reversed, when current flows from
the work to the electrode the oxide layer if lifted off, then current flows from the elec-
trode to the work this melts the metal and produce the weld, the repeated polarity
changes clean and melt the area to produce a continues weld.
