    摘要: A device for resistance welding includes a welding clamp housing, a welding transformer, a welding clamp, a welding clamp drive for operating the welding clamp and a power supply using alternating supply voltage. The device may be built as small as possible and may be simple to expand. The power supply is implemented by a main converter and by drive and welding converters. The output of the main converter is connected to the inputs of the drive and welding converters. The inputs of the drive and welding converters are connected to one another. These connections are implemented by an a.c. voltage intermediate circuit.

    摘要: A method for preventing excessive currents in a welding converter that, by use of power semiconductors, generates a two-phase, pulse-width-modulated a.c current from a rectified mains a.c. current supplied to the primary side of a welding transformer. The method includes the following method steps: detecting the current of at least one phase of the primary circuit by a sensor (20); for each detected current signal, forming the time derivation through differentiation according to the time; comparing the time-derived measured signal with a predetermined maximum value; and if the time-derived measured signal exceeds the predetermined maximum value, emitting a signal that leads to deactivation of the power semiconductors (16).
