  Elektrischer Lötkolben mit induktiver Heizung. 



   Gegenstand der Erfindung ist ein dauernd elektrisch beheizter Lötkolben, bei dem die   Wärme-   entwicklung auf die zum Löten benutzte Stelle beschränkt bleibt. Zu diesem Zweck ist der Kolben in bekannterweise als kleiner, mit Handgriff versehener Transformator ausgebildet und erfindungsgemäss der zum Löten dienende Metallteil als ein Teil von dessen   Sekundärwicklung.   Dadurch, dass man den Widerstand dieses Teiles der   Sekundärwicklung   erhöht, kann man die Wärmeentwicklung auf diese Stelle hohen Widerstandes konzentrieren. Dadurch wird erreicht, dass einerseits die primäre Transformatorwicklung nur wenig mitbeheizt wird und dass anderseits die Wärmeverluste durch Ausstrahlung auf ein Mindestmass verringert werden. 



   Die Fig. 1-3 der Zeichnung zeigen den Kolben in Längsschnitt, Ansicht und Querschnitt. 



   Der Transformator ist als Kerntransformator ausgebildet, dessen   Sekundärwindung,   der eigentliche

 wo die Hitze vorhanden sein muss, geringeren Querschnitt als an seinem übrigen Umfange. Die Abmessungen können leicht so gewählt werden, dass eine wesentliche Temperaturerhöhung durch Joule'sche 
 EMI1.2 
 kann durch die   Wärmeschutzschicht   unschädlich gemacht werden. 



   Unter   Umständen   ist es zweckmässig, die Streuung der Kraftlinien durch besondere Mittel zu verringern ; zu diesem Zweck kann ein die Teile 1 und 2 dicht umgebender, an der Vorderseite offener 
 EMI1.3 
 tragen, die in senkrecht auf der Längsachse stehenden Ebenen verlaufen und dicht bis an die Vorderschneide heranreichen.

  Electric soldering iron with inductive heating.



   The subject matter of the invention is a permanently electrically heated soldering iron in which the generation of heat remains limited to the point used for soldering. For this purpose, the piston is designed as a small transformer provided with a handle and, according to the invention, the metal part used for soldering is designed as a part of its secondary winding. By increasing the resistance of this part of the secondary winding, the heat development can be concentrated on this point of high resistance. This ensures that, on the one hand, the primary transformer winding is only slightly heated and, on the other hand, the heat losses due to radiation are reduced to a minimum.



   1-3 of the drawing show the piston in longitudinal section, elevation and cross-section.



   The transformer is designed as a core transformer, the secondary winding of which is the actual one
 EMI1.1
 where the heat must be present, a smaller cross-section than the rest of the circumference. The dimensions can easily be chosen so that a substantial temperature increase by Joule is
 EMI1.2
 can be rendered harmless by the heat protection layer.



   Under certain circumstances it is advisable to reduce the scattering of the lines of force by special means; for this purpose, the parts 1 and 2 tightly surrounding, more open at the front

 that run in planes perpendicular to the longitudinal axis and come close to the front edge.
