Abstract
An improved electrode for use in a plasma arc torch. The electrode includes an electrode body, a bore defined by and disposed in the electrode body, and an insert disposed in the bore. The insert and/or the bore of the electrode are configured to improve retention of the insert in the electrode, thereby extending electrode life. The invention also includes a method for forming the electrode. The method includes a step of positioning an insert into a bore of an electrode such that an exterior gap is established that is greater than a second gap.
