A wave solder nozzle is capable of delivering solder material to perform a wave soldering operation on a printed circuit board in an inert atmosphere. The wave solder nozzle includes a front plate and a back plate coupled to the front plate. The front plate and the back plate define a channel through which solder material flows. The nozzle further includes an exit trough extending from the back plate. The exit trough has a weir provided at one end of the exit trough. The exit trough is constructed and arranged to control the flow of solder material from the wave solder nozzle. A surface of the exit trough is wettable to improve the flow of solder material out of the wave solder nozzle. A method of improving the flow of solder material through the nozzle is also disclosed.
