CLEANING DEVICE FOR AN ARC WELDING TORCH OR CUTTING TORCH COMPRISING A JET NOZZLE WITH TWO CONCENTRIC EXIT REGIONS AND CORRESPONDING METHOD

摘要

The invention relates to a device (10) and a method for cleaning contaminants from an arc welding torch or cutting torch using a cold jet of an agent which is applied to the individual functional parts of the torch by means of a jet nozzle. The jet nozzle comprises at least two concentric exit regions (22, 24) for the jet and configured to form at least two sub-streams with different flare angles in order to simultaneously and comprehensively expose all the functional parts of the torch that are to be cleaned to the cold jet. This permits a large tolerance range for the positioning of the torch head in relation to the positioning of the jet nozzle without having a detrimental effect on the cleaning result. ® KIPO & WIPO 2008
