TIG welding system

摘要

A TIG welding system is provided including 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, the electrode having a length and a diameter; an amperage input in communication with the controller and adapted to receive a user-selected welding amperage; wherein in the controller is programmed to select one of the at least one waveform based on the user-selected amperage 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 is configured to prevent user control of an arc current or voltage, wherein upon attaining a steady state at the user-selected welding amperage, the controller is configured to permit user control of the arc current or voltage applied to the electrode.
