ABSTRACT:
In a soldering device comprising at least one stirrup electrode that is secured to a soldering stirrup holder and is heatable with electrical resistance heating and has two soldering webs lying opposite one another or four soldering webs lying opposite one another in pairs, the working surfaces at the underside of the soldering webs should be capable of being placed exactly parallel onto the soldering location that lies, for example, on a printed circuitboard. This is enabled by a flexible suspension of the soldering stirrup holder which provides a pivot compensation center lying centrally in the plane of the working surfaces. As a result thereof, a reliable contact of the parts to be soldered to one another and to the soldering stirrups is guaranteed.
