Plasma arc torch continuity device and methods of use therefor

A continuity device for use in a torch height control system of a plasma arc torch is provided that comprises a reattachable engagement member, a connection member, and a contact member in electrical continuity with the connection member and disposed distally from the reattachable engagement member. Accordingly, when the reattachable engagement member is secured to a proximal component of the plasma arc torch, the contact member is in electrical contact with a distal component of the plasma arc torch, thereby providing electrical continuity to the torch height control system through the connection member. Advantageously, the continuity device is reattachable and thus provides for ease of use and replacement of components, such as consumables, of the plasma arc torch. Additionally, methods of using the reattachable continuity device are provided, wherein a distal component of the plasma arc torch contacts a workpiece and electrical continuity is provided through the reattachable continuity device.
