Abstract
A device and methods are provided, the device comprising a conductive union disposed in a conductive holder, a first fitting capable of coupling with the holder and fluidly communicating with the conductive union, and a spray tip disposed in the fitting and communicating with the conductive union along an axis. The device also comprises a ferrule and fitting capable of coupling with a second holder and communicating with a second conductive union, a tube disposed in the ferrule and fluidly communicating with the first conductive union and the spray tip along the axis. The assembly also includes an insulating member removably secured to the first and second conductive unions to electrically insulate them when they are electrically connected to first and second voltage levels, respectively.
