<p>A plasma arc torch (100, 400) includes a cathode adaptor body (501) having at least two sealant channels with sealant rings. The torch (100, 400) also includes a cathode body (505) having at least two sealant channels with sealant rings. The torch (100, 400) further includes a pilot arc connector (509) having at least two sealant channels with sealant rings. The torch (100, 400) additionally includes a rear isolator (513, 513') that includes at least two sealant channels with sealant rings that engage an anode body (519) and are spaced apart from each other by a distance that is in a range of 2 percent to 50 percent of an over all length of the rear isolator (513, 513'). The rear isolator (513, 513') also includes at least two sealant channels with sealant rings that engage a ring isolator (521) 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 (513, 513').</p> |
