Abstract
To reduce energy losses for a welding device when on stand-by and to enable a clean and controlled start of the welding phase, a DC-to-DC converter of the welding device converts an input DC voltage present at an input connection to an output DC voltage present at an output connection. At least one switch element of a branch of the DC-to-DC converter is switched with a switching frequency, and a welding phase is provided for the welding device, during which the switching frequency corresponds to a normal switching frequency. A stand-by phase is provided for the welding device, during which the at least one switch element is switched with a switching frequency corresponding to a stand-by switching frequency which is lower than the normal switching frequency.
