Seam welding machine / variable-speed - LWC series
Standard designs have welding lengths ranging from 72” (1825 mm) to 240” (6100 mm)The seam welder is capable of welding either the external or the internal seams of cylindrical parts. When used as an external seam welder a maximum diameter of 55” (1400 mm) can be welded and the minimum external part diameter depends on the length of the seam welder. When used as an internal seam welder the machine will accommodate a 55” (1400 mm) minimum inside diameter up to any diameter that you can conveniently handle.
