ENGINEER 391 Universal Flue Welding Machine PERHAPS the most distinctive Feature of the universalflue welder manufactured by the Southwark FoundrySi Machine Co., Philadelphia, Pa., is the fact that itwelds the flue on the inside thus making the inside diameterat the weld the same .1- throughout the Hue. This allows afree passage of gases especially in superheater flues, also ft* ^£2^. i ]■■■■■ H 1 Front View of Southwark Flue Welder with Heat Deflector Removed eliminating the possibility of superheater units sticking inapplication. The machine is built sufficiently heavy to weldlarge flues and it takes safe ends of lengths from 6 in. to 4 in. Among the advantages claimed for the machine arerelatively small power consumption, closeness of the furnace to the welding head, and a single foot valve controlling alloperations.
