Abstract (en)

[origin: WO2005102584A1] Process and devices for cleaning welding torches (10), for example in automated welding lines, on welding robots and in single-piece production, by means of a cold medium, preferably CO2 dry ice, the CO2 snow produced by expanding the pressurised liquid CO2 being directly applied with low density in a uniform or intermittent manner to the surfaces to be cleaned of the contact pipe (12) and gas nozzle (13) by means of a cleaning head (8) that fits the burner (10).
