Abstract: A welding current source for providing a welding current and a welding voltage at an output in order to carry out an arc welding process includes an input-side rectifier, an inverter, which is operated with a switching frequency, a transformer having a primary winding and at least two secondary windings, at least two rectifiers arranged between the secondary windings and the output, and at least one capacitor and one load resistor at the output. At least one current-limiting reactor is arranged on the second secondary winding and the load resistor for discharging the capacitor, which can be charged by the current-limiting reactor, the current-limiting reactor, and the capacitor are dimensioned in such a way that the maximum value of the no-load voltage at the output is greater than the voltage corresponding to the transmission ratio of the primary winding to the secondary winding of the transformer.

Abstract: The invention relates to a device for applying at least one application agent to hair, comprising a housing unit (11a; 11b; 11c) which at least partially encloses at least one depot volume (12a; 12b; 12c) for accommodating at least one component of the at least one application agent (10a; 10b; 10c). According to the invention, the device comprises a dispenser unit (13a; 13b; 13c) which is designed to discharge the at least one component of the application agent (10a; 10b; 10c) from an application agent container (14a; 14b; 14c) that is at least partially inserted into the depot volume (12a; 12b; 12c).

Abstract: The invention starts out from an applicator for applying at least one application medium (10a; 10b; 10c, 52c) to hair, with a separation unit (11a; 11Ib; 11c), which forms at least two application gaps (12a, 13a, 14a, 15a, 16a; 13b; 12c, 13c, 14c, 15c, 16c) that are provided for receiving some of the hairs for application of the application medium (10a; 10b; 10c, 52c). It is proposed that at least one of the application gaps (12a, 13a, 14a, 15a, 16a; 13b; 12c, 13c, 14c, 15c, 16c) has an opening width that is smaller, at least by a factor of 10, than a distance between the application gaps (12a, 13a, 14a, 15a, 16a; 13b; 12c, 13c, 14c, 15c, 16c).

Abstract: The invention relates to an applicator device for applying at least one application agent (10a) to fibrous material, in particular an applicator device for applying an application agent (10a) to hair. Said device comprises a housing unit (11a) that contains at least one depot volume (12a) for storing the application agent(s) (10a) and at least one application volume (13a) that is connected to the depot volume (12a).
