An apparatus for evaluating an electrical insulator includes: a frame having a base and a pair of spaced-apart resilient arms each having a distal end; and a flexible probe disposed between the arms, the flexible probe being generally U-shaped and having a pair of distal ends, each distal end of the probe being connected to a respective distal end of one of the arms.

A plasma torch head adapted to cut longitudinal slots in tubes from the interior is disclosed. The plasma torch head includes an outer body made of reinforced fiberglass. An adhesive is used to affix fiberglass components of the torch head together to form a gas tight seal. As a cut is made, the outer body of the torch becomes charred. At the end of each cut the torch head is either replaced or rebuilt. Gas to support the plasma and electric power is supplied to the torch head via an electrically conductive tube concentric with the major axis of the torch head.
