\TTIG - Tungsten Inert Gas

Welding using tungsten electrode creates an electric arc protected by ionized argon gas, when the filler material is provided on the side, usually manually by cutter. Because of the use of gas from the oxygen mask, the filler material is coated.





  MIG - Metal Inert Gas 

Welding using a metal electrode and an electric arc. The electrode is the filling material and the welding point is fed mechanically by blowtorch itself.
