Leponitt Soldering Iron Temperature ControllerThe Leponitt Rheostat regulates the flow of current into your soldering iron to maintain a consistent tip temperature as you work. With a 250 watt capacity and 3 prongs, the Leponitt Rheostat works with most irons. Solid state circuitry gives you solid temperature control all the time. Solder more effectively and efficiently with nearly any soldering iron. Use with all soldering irons and other non tip controlled irons. Three prong outlet for
