Abstract
A metal spray gun of the arc spray type has a nozzle-positioner member of electrically insulating material that is disposed between a gas inlet and an arc zone. A primary stream of gas is flowed through a through passage in the nozzle-positioner member, and seat surfaces in the through passage receive tips of individual electrically conductive contact tube assemblies that are biased outwardly away from one another. The nozzle-positioner member aligns the contact tube assemblies and configures the gas stream such that each metal wire is immediately enveloped in gas flow as it emerges from its contact tube and remains in that enveloping gas flow throughout the region between the contact tube tip and the arc zone. The spray gun produces quality metal spray coatings with lower gas pressures and has lower noise levels.
