Abstract
A torch having an adjustable length. The torch may include a first housing portion and a second housing portion. The second housing portion may be slidably coupled to the first housing portion. The second housing portion may be configured to slide along a longitudinal direction of the torch to adjust a length of the torch.
Claims19
A plasma arc torch, comprising:
- a first torch housing portion;
- a second torch housing portion slidably coupled to the first torch housing portion, wherein the second torch housing portion is configured to slide along a longitudinal direction of the plasma arc torch to adjust a length of the plasma arc torch, the second torch housing portion being slidable between a first position in which the second torch housing portion and the first torch housing portion span a first length and a second position in which the second torch housing portion longitudinally extends from the first torch housing portion so that the second torch housing portion and the first torch housing portion span a second length greater than the first length;
- an electrical connection for plasma cutting power comprising a first tube fixed to the second torch housing portion and a second tube disposed within the first torch housing portion, the first tube and the second tube being nested within one another and being configured to slide along one another such that the first tube extends further beyond the second tube when the second torch housing portion is in the second position than when the second torch housing portion is in the first position, so that the electrical connection is configured to slidably extend or slidably collapse as the second torch housing portion moves between the first position and the second position to deliver the plasma cutting power regardless of the length of the plasma arc torch;
- and
- a pilot electrical connection configured to provide a pilot connection regardless of the length of the plasma arc torch, the pilot electrical connection being provided separately from the first tube and the second tube.

A plasma arc torch, comprising:
- a first torch housing portion including a handle;
- a second torch housing portion including a torch head portion on which consumables are installed and a neck portion that is at least partially received by a conduit of the first torch housing portion, the second torch housing portion being slidably coupled to the first torch housing portion so that second torch housing portion is configured to slide along a longitudinal direction of the plasma arc torch to adjust a length of the plasma arc torch, the second torch housing portion being slidable between a first position in which the torch head portion of the second torch housing portion is proximate the first torch housing portion and a second position in which the torch head portion is longitudinally separated from the first torch housing portion;
- and
- an electrical connection for plasma cutting power comprising a first tube fixed to the second torch housing portion and a second tube disposed within the first torch housing portion, the first tube and the second tube being nested within one another and being configured to slide along one another such that the first tube extends further beyond the second tube when the second torch housing portion is in the second position than when the second torch housing portion is in the first position so that the electrical connection is configured to slidably extend or slidably collapse as the second torch housing portion moves between the first position and the second position to deliver plasma cutting power regardless of the length of the plasma arc torch.
