Abstract
The electrode has a durable upper part and a consumable tip. A plurality of copper tubes extend through the upper part. The connection to the consumable tip is by means of an intermediate plate and a nipple, the latter containing ducts for the connection of the copper tubes. At the upper end of the electrode, the copper tubes are serially interconnected by tube bends and at their lower end by ducts in the nipple.
