A container for packaging and unwinding a welding wire having a natural cast that is essentially a straight line. The container including a box with vertical side walls each having an inner wall surface and vertically extending corners between the side walls, a closed bottom, a top opening for removing the welding wire. Th e container further including a first vertically extending cylindrical liner with a firs t radial outwardly facing surface and a first radial inwardly facing surface wherein the first inward surface has a diameter A and is coaxial with a vertically extending container axis such the first liner is supported by the side walls. The container further includes a secon d cylindrical liner having a second radial outwardly facing surface and a second radial inwardly facing surface. The second outward surface having a diameter B that is less than diameter A and is coaxial with the axis. The second outward surface defining a radial inward extent of an annular wire cavity and the first inward surface defines a radial outward extent of the annular wire cavity. The container also including a wi re coil made up of a plurality of convolutions of the wire. Each of the convolutions havi ng a similar effective convolution diameter that is greater than fifty percent of diamete r A but less than diameter A. The natural cast producing a radially outward force in the each convolution that is supported by the first liner and the coil extending radially between the first and second liners.
