Abstract
The plasma gun assembly of the invention is particularly suitable for coating the inner surfaces of narrow cavities, bores, channels or the like. It essentially comprises a plasma gun head member, a plasma gun shaft member and a connector member. These three units are designed as replaceable modules which can be replaced by the operator of the plasma gun assembly quickly and easily. The plasma gun head member is connected to the plasma gun shaft member by means of only two screws, and the connector member is connected to the plasma gun shaft member by means of only three screws. All channels, conductors and conduits for supplying the media and the electric energy required for the operation of the plasma gun assembly are running in the interior of the plasma gun shaft assembly.
