Patent ID: 7423235

Claim:
A thread configuration of a plasma arc torch electrode for being threadedly engaged in a corresponding thread configuration in a plasma arc torch comprising: a threaded portion for threadedly holding the electrode within the plasma arc torch and defining at least one thread form extending helically and at least partially around a thread axis, the threaded portion defining; a major diameter comprising a larger diameter of the threaded portion, a minor diameter comprising a smaller diameter of the threaded portion, a mean diameter between the major diameter and the minor diameter, a crest portion extending in one direction from the mean diameter and defining a width along the mean diameter, a root area extending in an opposite direction from the mean diameter than the crest portion and defining a width along the mean diameter, and wherein the width of the root portion of the electrode is at least about 35% greater than the width of the root area of the corresponding thread configuration in the plasma arc torch.
