Abstract
An adjustable welding furnace includes a gimbal-mounted furnace housing within which a workpiece may be preheated and subsequently welded. A removable cover is mounted over an access opening in the housing for pivotal movement along either of two edges of the opening. A rotatable spit assembly, which may be mounted in any of several positions on the housing, suspends the workpiece within the housing for rotation independent of pivotal movement of the housing. A drawer-mounted heating assembly may be easily removed from the housing for servicing.
