Disclosed herein is a fluid baffle assembly suitable for use in water-cooled welding or cutting torches for providing a fluid passageway for efficient cooling of the torch head. The baffle assembly is comprised of a thin arcuate baffle member held in compression within the cylindrical outer sleeve of the torch head and about the inner body portion of the torch head so as to bifurcate the upstream portion of the water cooling area between the sleeve and the outer body portion of the torch head into separate water inlet and outlet channels. The inlet and outlet channels terminate at the lower end of the baffle in an annular water cooling chamber and at their upper ends communicate with water inlet and outlet tubes so that cooling water can flow from the inlet tube down the inlet channel, about the lower portion of the torch head in the annular water cooling chamber and out the outlet tube via the outlet channel.
