Abstract: A pipe fitting apparatus for holding a pair of pipe fittings together such that the pipe fittings may be welded. The apparatus is designed for use by a single operator. The apparatus comprises a pair of handles interconnected by a conventional locking toggle apparatus and having first and second clamping jaws extending from the handles such that the first and second clamping jaws may be clampingly engaged with a first pipe fitting. A lower support extends from one of said clamping jaws and provides adjustable support for a lower portion of a second pipe fitting adjacent to the first pipe fitting. An upper support provides supporting engagement for a distal upper end of the second pipe fitting and includes an arm holder attached to one of the clamping jaws and a support arm slidably connected to the arm holder and which may be locked in a supporting position.
