ABSTRACT:
An torch head and cable assembly is disclosed having improved electrical insulation, an anti-rotational, space-efficient handle and a more efficient power cable. The torch head has a seal using inner and outer sealing walls to insulate an operator from high frequency electric energy. A handle and handle connector on the torch head have complementary polarized cross-sections to form an anti-rotational connection. The cross-section on the handle minimizes wasted space around cables positioned inside the handle and cooperates with a power cable having at least two wires to supply electric current to the torch head in an efficient manner.
