Heating up from the room temperature to 300°C within 30 seconds. This tool is used in the fields of electronic research, teaching and production, especially in the repairing and soldering fields of electronic appliances and communication equipment -The soldering iron tool is controlled automatically by the micro-processor. The digital control electronics and high-quality sensor and heat exchange system guarantee precise temperature control at the soldering tip. The highest degree of temperature precision and optimal dynamic thermal behaviour under load conditions is obtained by the quick and accurate recording of the measured values in a closed control circuit.
