The swirl ring comprises a first opening disposed within a portion of the proximal end of the body, a second opening disposed about a central portion of the body, and a third opening comprising at least one swirling port disposed within a portion of the distal end of the body. The third opening is configured to provide a swirling flow of the plasma gas about the electrode at the distal end of the body.
