Claim:
1. Equipment for cleaning welding torches comprising: a reserve of a pressurized fluid comprising CO2; and a dispensing device connected to said reserve to receive said pressurized fluid and dispense onto a welding torch a flow of solidified CO2 microparticles produced by expansion in the external environment and consequent cooling of said fluid received from said reserve, wherein said dispensing device comprises: a regulating valve to regulate the rate and intensity of said flow of solidified CO2 microparticles supplied to said welding torch, a dispensing nozzle fixed at the exit of said dispensing device to generate and dispense said flow of solidified CO2 microparticles onto said welding torch, and an adapter sleeve associated with said dispensing nozzle and designed to receive the external body of said welding torch; wherein said dispensing device is designed to couple with said welding torch to be cleaned via a male-female coupling, with the adapter sleeve acting as the female part with respect to the outside of an external body of the welding torch and with the tip of said dispensing nozzle acting as the male part with respect to the inside of the external body of the welding torch in said coupling, and wherein said dispensing nozzle of said dispensing device has along its axis a central pipe and, at one outwards-facing tip end, a series of holes and grooves, with said central pipe, said tip end and said holes and grooves being configured to suitably direct, at the output of the dispensing device and towards the interior of the welding torch, the flow of CO 2 microparticles, and with said holes extending, in said tip end of the dispensing nozzle, in the perpendicular and radial directions relative to the axis of the central pipe so as to convey and perpendicularly direct at least a part of the flow of CO 2 microparticles.
