Abstract:
A plasma arc torch includes a cathode adaptor body having at least two sealant channels with sealant rings. The torch also includes a cathode body having at least two sealant channels with sealant rings. The torch further includes a pilot arc connector having at least two sealant channels with sealant rings. The torch additionally includes a rear isolator that includes at least two sealant channels with sealant rings that engage an anode body and are spaced apart from each other by a distance that is in a range of 2 percent to 50 percent of an overall length of the rear isolator. The rear isolator also includes at least two sealant channels with sealant rings that engage a ring isolator and are spaced apart from each other by a distance that is in a range of 2 percent to 50 percent of the overall length of the rear isolator.
