Abstract: The invention relates to a method and a device (30) for monitoring the inert gas (5) during a welding process performed using a welding torch (7), wherein at least one measurement variable (Pi), which is dependent on the type of inert gas (5), is measured by means of at least one sensor (Si). According to the invention, at least two measurement variables (Pi) of the inert gas (5) are measured and the measured values (Mi) of the at least two measurement variables (Pi) of the inert gas (5) are compared with several stored values (Mi?), which are associated with inert gas types (Gi), of the at least two measurement variables (Pi), and the inert gas type (Gi), for which the assigned values (Mi?) of the at least two measurement variables (Pi) are closest to the measured values (Mi) of the at least two measurement variables (Pi) of the inert gas (5), is displayed.

Abstract: A heat sink for cooling electronic power components arranged in a housing includes a cooling element having cooling fins arranged on a base surface, and a fan for intake of ambient air and for delivering the ambient air via the cooling fins of the cooling element, the cooling element having a recess, in which the fan is arranged spaced apart from the base surface. The fan includes a housing ring on the side facing away from the base surface of the cooling element, an intermediate space being formed between the bottom edge of the housing ring and the base surface of the cooling element. The fan is an axial fan, so that the ambient air taken in impinges upon the base surface of the cooling element, is deflected by essentially 90 degrees and guided through the intermediate space laterally between the cooling fins to the outside.
