This Delcast Solder Reel offers ready access to solder and an effortless draw for the user. The reel positions solder spools in an upright position, allowing solder to neatly unwind as it is threaded and drawn through loop at the end of the adjustable dispenser arm. Package includes one 100g each of 0. 6mm and 0. 8mm rosin core 63/37 tin lead solder wire. Solder is comprised of a eutectic ratio of 63% tin to 37% lead, meaning it has the lowest melting point of any other tin to lead mixtures and a lower melting point than either of the two parts by themselves. The low melting point of this solder is ideal for working on sensitive electronics which can otherwise be damaged by exposure to high temperatures. It has a true melting point of 183 Celsius / 361. 4 Fahrenheit.
