An electrode for a plasma arc torch includes a conductive body and a plurality of emissive inserts. The conductive body includes a proximal end portion, a distal end portion and a cavity extending from the proximal end portion to the distal end portion. The distal end portion defines a distal end face. The plurality of emissive inserts extend through the distal end face. The conductive body further defines a dimple extending into the distal end face and at least partially into the emissive inserts. The dimple is positioned concentrically about a centerline of the conductive body.
