  • Variable temperature high frequency induction heating soldering iron
    Patent number: 5408072
    Abstract: The present invention generally relates to a high frequency soldering iron. In particular, the soldering iron of the present invention is provided with a tip which is directly heated for a quick heating to a desirable temperature set by a temperature setting means. The soldering iron is also provided with a sensor for detecting the temperature of the soldering iron tip. A temperature comparator compares the sensed tip temperature against the set soldering temperature to maintain the tip temperature constant at the set temperature.
