In conventional TIG welding, the arc provides the entire energy required for heating and melting the filler wire, hence the metal deposition rate is limited by the rate at which the heating and melting process can take place. (W 81) (1)

Filler wire = Cabo alimentador

In this paper, dispersion curves has been generated for insulated wire and used to describe the modes behavior. (W 144) (2)

Insulated wire = Cabo isolado

In more recent developments, two wires were fed through one torch with a common contact tip, either with one or two power sources. This process is referred to as twin wire or double wire MIG/MAG welding. However, it was not until the process was developed with two electrically isolated contact tips in the same torch that the single torch process has become viable. (W 454) (3)

Twin wire = Cabo duplo
