Abstract
Plasma arc torches are provided that include a mounting for an electrode and a coolant tube telescopingly mounted on the plasma arc torch to engage and deliver coolant to electrodes of different sizes mounted in the mounting. The telescopingly mounted coolant tube may extend to a closed position in which coolant does not flow when no electrode is mounted in the mounting. The telescopingly mounted coolant tube may further be used to electrically connect a cathodic member with the electrode mounted in the mounting.
