    Abstract: The invention concerns a device for externally cooling a plasma torch. The invention concerns a device for cooling a plasma torch in which the electrode(s) and plasma fluid and cooling circuits are housed in a tubular casing, wherein the cooling device includes an independent sheath surrounding at least one main portion of the tubular casing and formed of two concentric casings, at least one cooling fluid inlet and at least one outlet disposed at the proximal extremity of the sheath, a system of baffles being disposed between the two casings of the sheath so as to constitute between the inlet and outlet a cooling circuit substantially covering the entire surface of the sheath, the inlet and outlet being connected to a suitable cooling fluid source.
