Abstract
Embodiments of arc plasma cutting torches are disclosed. In one embodiment, an eccentric plasma cutting torch includes an upper portion and a lower portion. The lower portion is angled on one side along a length λ which results from continuously smaller cross sections of the lower portion which are biased towards a non-angled side of the torch. As a result, a central axis of an electrode of the torch, used for cutting, is biased by an offset from a central axis of the upper portion towards the non-angled side of the torch. Such an offset allows for a torch tip region of the torch to get closer into otherwise difficult-to-access portions of workpieces for cutting. Furthermore, the overall dimensions of the torch are configured such that cooling elements within the torch dissipate enough heat to keep the torch in a stable operating condition during a cutting operation.
