Zusammenfassung:	The present disclosure is generally directed to a high temperature lubricant for use in a preheated welding wire system. The lubricant may comprise one or more high melting point materials in a concentration from 0.5 to 30 wt % by weight of the lubricant. The high melting point materials may comprise graphite, molybdenum disulfide, tungsten disulfide, or boron nitride. The lubricant is configured to remain on a welding wire electrode that has been coated with the lubricant without melting when a preheater heats the welding wire electrode to an elevated temperature (e.g., between 500 and 900 degrees Celsius). The lubricant may be a powder or a liquid. When the lubricant is a liquid, it may further comprise a solvent such as 2-proponal or water.
