Abstract: Method of controlling the temperature cycle at soldering points during laser soldering by recording a known fixed temperature point. Prior art methods record the instant at which the solder melts by detecting the rest point in the temperature/time curve and switch the laser off immediately or after a short time. To improve the measurement tolerances, use is made, according to the invention, of a sensor substance which has a specified adjustable Curie point and which is in thermal contact with the soldering point. The temperature of the soldering point and of the sensor substance are approximately equal. The detection of the magnetic phase transition, for example by means of a differential transformer, consequently makes it possible to determine the point in time at which the Curie point is exceeded. Since the transition between ferro-magnetism and para-magnetism takes place in a narrow tolerance interval, an extremely precise measurement is possible. <IMAGE>

Abstract: A current leakage control circuit regulates the output power of an electrosurgical generator to limit the amount of leakage current. The leakage current is monitored with a differential transformer which has the output and return leads of the electrosurgical generator as first and second windings. A third or sense winding produces a control signal whenever the currents in the output and return leads are not equal, thus indicating current leakage. The control signal is compared to a predetermined maximum safe level of leakage current. If this predetermined level is exceeded, a power control feedback loop of the electrosurgical generator reduces the output power to a sufficiently lower level to reduce the leakage current within a maximum acceptable limit.
