In resistance welding of contacts, in general, dissimilar materials are to be joined. To this
end, copper and brass alloys are used as insulators, however, depending on the application,
also steel sheets with different metal coatings are used. The contacts normally consist of a
material with a good conductivity (copper, silver, gold, etc.) which is, on the one hand,
advantageous for the functioning of the produced parts but which, however, puts demands on the
welding technique.
Moreover, the contacts are normally produced with so-called high-speed machines with very high clock rates. The welding power sources which are used for this process must fulfil the following demands:
The high-frequency inverters of the SPATZH6000 series are particularly suitable for this application as they meet all the above-mentioned demands. The individually settable limit value- and alarm management of these power sources guarantee the steady, good quality standards of the produced parts.
