Brazed joints on lapped flat copper wires, for example, which are encountered in diverse forms in electrical machine construction, are easy to produce with the aid of our pistol-type brazing tongs.
The generator is equipped with a cable output (up to 10 m long) at the end of which the coaxial handheld transformer with the easy-to-use, pneumatically operated brazing pistol is connected. Very high quality demands are placed on the joints of the winding elements, which can be met in this form only by the inductive heating method. For example, temperatures produced in the brazing points and in adjacent regions must be precisely limited. In addition, the brazing points are often poorly accessible. The brazing tongs, flexibly guided by a balancer, can perform well in this case.
Operation is simplicity itself. By means of a hand-operated switch on the pistol, the pneumatically operated plunger is actuated in the first position. The preset power value is started on the generator in the second position in order to achieve the same brazing quality every time.

System description:
The presented brazing method for joining copper lines in electrical machine construction is carried out with our inductive heating systems of the types eldec MFG 15 and MFG 10 or MFG 5 with special brazing tongs (brazing pistol) fastened on the coaxial handheld transformer. The picture depicts the eldec tabletop MFG 15 with IGBT transistor technology, here with a simple ring inductor instead of brazing tongs. The coaxial handheld transformer is connected to the generator with an up to 10-m-long flexible cable.
