摘要
Process for cooling resistance spot welding devices comprises conveying a cooling water stream temporarily limited during the operative welding process via a cooling water line (4) to the sites of the device to be cooled and then via a cooling water line (6) to a cooler. An Independent claim is also included for an apparatus for carrying out the process comprising a conveying device having a cylinder-piston unit (7). One piston side of a conveying piston (9) in the cylinder (8) limits a pump chamber (12) having a volume corresponding to the cooling water requirement of the welding process. The piston is connected to a drive and the pump chamber is connected to the water lines (4, 6).
