Abstract
A liquid coolant tube for a plasma arc cutting torch including a hollow elongated inner body shaped to translate within a hollow elongated outer body. The hollow elongated outer body of the liquid coolant tube is shaped to fixedly connect to the plasma arc cutting torch and includes a set of electrode guides. An external surface of the hollow elongated outer body and the set of electrode guides partially define a set of coolant flow channels between the set of electrode guides. The set of electrode guides are shaped to facilitate alignment of an electrode within the plasma arc cutting torch.

A liquid coolant tube for a plasma arc cutting torch, the liquid coolant tube comprising:
- a hollow elongated inner body shaped to translate within a hollow elongated outer body;
- and
- the hollow elongated outer body comprising a set of electrode guides extending along an outer surface of the hollow elongated outer body, the hollow elongated outer body shaped to fixedly connect to the plasma arc cutting torch,
- wherein an external surface of the hollow elongated outer body and the set of electrode guides partially define a set of coolant flow channels extending along an outer surface of the hollow elongated outer body between the set of electrode guides, the set of electrode guides shaped to facilitate alignment of an electrode within the plasma arc cutting torch.
A liquid coolant tube for a plasma arc cutting torch, the liquid coolant tube comprising:
- a hollow elongated outer body having a distal end and a proximal end, the proximal end of the hollow elongated outer body configured to be fixedly connected to the plasma arc cutting torch;
- and
- a hollow elongated inner body having a distal tip and a proximal tip, and shaped to translate within the hollow elongated outer body,
- wherein the hollow elongated inner body is shaped and dimensioned to be supported by the hollow elongated outer body proximate the distal tip and proximate the proximal tip, and
- wherein an axial translation of the hollow elongated inner body relative to the hollow elongated outer body increases a first distance between the distal tip of the hollow elongated inner body and the distal end of the hollow elongated outer body and decreases a second distance between the proximal tip of the hollow elongated inner body and the proximal end of the hollow elongated outer body.
