Metcal MX-500 Soldering and Rework System have been reimagined, adding features and a new look to a bench top icon. The system utilizes Smart Heat® Technology, where each cartridge is equipped with a self-regulating heater which Senses its own temperature and closely maintains its pre-set idle temperature for the life of the heater-tip. The tip temperature is determined by the inherent metallurgical properties of the heater; no external adjustment or equipment is required. The MX-500 retains switchable dual port, 40W operation while introducing numerous new features in a new housing.
