Abstract
A cooling arrangement for cooling weld caps of a welding device includes a local cooling pipe having a feed portion through which coolant can flow to the weld caps, and a return portion through which coolant can flow away from the weld caps. The cooling arrangement has at least one sensor and at least one actuator arranged at the cooling pipe. A check device is connected to the sensor and the actuator. The check device is arranged in an immediate vicinity of the sensor and/or the actuator and/or the local cooling pipe, and is adapted to receive measured values of the sensor and to check, based on pre-established criteria, whether the measured values are within a predefined desired range. In response to a negative check result, the check device can drive the actuator in a predetermined manner such that the cooling arrangement is placed in a safe condition.
