Plasma torch with reversible baffle
Abstract:
A plasma arc torch includes an annular baffle defining distinct faces A, B, C, and D. Faces A and C are opposite from each other, and faces B and D are opposite from each other. First passages for fluid flow extend between the faces A and C, and second passages extend between the faces B and D. The baffle is installable in an annular space between an inner wall and an outer wall, in either of two orientations. In a first orientation, the first passages are open to fluid flow and the second passages are closed by engagement of the inner and outer walls with the faces B and D, and in a second orientation, flipped over relative to the first orientation, the second passages are open to fluid flow and the first passages are closed by engagement of the inner and outer walls with the faces A and C.
