<p>An electrode for a plasma arc torch is provided by the teachings of the present disclosure. In one form, the electrode includes a conductive body, a plurality of deformed emissive inserts, and a dimple. In one form, the plurality of emissive inserts are concentrically nested about the centerline of the conductive body, and the dimple is positioned concentrically about a centerline of the conductive body. The plurality of emissive inserts and the dimple increase the life of the electrode.</p> |
