Abstract: A managing system for eSIM profiles has at a central site, an eUICC unit and a central unit. The eUICC unit is capable to host a multitude of eUICC cards. The eUICC unit is in signal connection with a selectable download assistant module. The central unit is in connection with the eUICC unit to manage the eUICC unit. The download assistant module is embodied to establish a connection with a network component of a mobile network at a local site. The local site is connected to the central site via an internet connection. A managing system results having enhanced capabilities for managing eSIM profiles. The managing system may be part of a test system further having at least one test probe being in signal connection with the central unit of the managing system.

Abstract: For welding conductive materials, using conventional copper electrode caps, with a long service life of the welding tool, a foil section is provided between the electrode cap and the surface of the sheet. The foil section is part of a foil strip which is displaceable relative to the electrode cap, and consists of a material with a high nickel content, while silver or a silver metal oxide is provided as a material in the contact area between the electrode cap and the foil section. The electrode cap is preferably coated with this material.
