1. A TIG welding system comprising:
a power source having a controller in communication therewith, the controller having a memory storing at least one waveform; a welding torch including an electrode electrically connected to the controller; an arc initiation input in communication with the controller, said arc initiation input comprising:
an electrode color; andan electrode diameter; wherein in the controller is programmed to select one of the at least one waveform based on the user-selected electrode color and electrode diameter and apply power from the power source to the electrode according to the selected at least one waveform; wherein the at least one waveform includes an arc initiation stage including at least one pulse, wherein during the arc initiation stage, the controller controls at least two of the parameters of an arc starting current, an arc strike time and an arc slope time, and wherein upon attaining a steady state at the combination of electrode color and electrode diameter, the controller is configured to permit user control of the arc current or voltage applied to the electrode. |
