An electrode assembly having a tubular support jacket that defines an internal compartment. The internal compartment is actively cooled by coolant. An electrode tip is coupled to the tubular support jacket. The electrode tip receives electricity through the tubular support jacket. An insulator construct surrounds at least part of the tubular support jacket. The insulator construct includes an insulation base, an insulation tube and an insulation cap. A gas supply conduit is interposed between the tubular support jacket and the insulation tube, wherein the gas supply conduit receives a working gas from a working gas supply. A thermally conductive casing surrounds at least part of the insulator construct. The thermally conductive casing is actively cooled. The thermally conductive casing actively cools the insulator construct, the underlying tubular support jacket, and thus the electrode tip. The active cooling reduces over-heating of the electrode tip and prevents excessive consumption and erosion.
