Plastic reels (MIG wire)

From GAWDAwiki

MIG wire can be supplied as a continuous coil wound onto cylindrical reels or spools of various designs and diameters. Traditionally, MIG reels are made of plastic. Reel sizes vary from the standard 300mm diameter reels to small, 50mm diameter, for spool-on-gun equipment. The amount of wire will vary with reel diameter and type of alloy, a standard reel holding about 15kg of steel MIG wire, or 6kg of aluminum MIG wire. ^[1]
