Offering automatic fluxing system for applying flux to  articles on a production line basis. The system includes an automatic spray gun with a movable mounting for directing the flux onto articles being presented to the spray gun by a conveyor. The system includes automatic nozzles controls and a flux supply system for the nozzles, particularly adopted for handling corrosive, abrasive and highly viscous fluxes. The flux supple system includes a special pump for continuously circulating flux in the reservoir in addition to continuously suppling flux to the nozzle. The circulating reservoir eliminates the need for flux agitators and also permits the flux to be heated and maintained at a uniform pre-set temprature making the flux supply independent of pump indued temprature variation and of temprature related viscosity changes. Stainless steel conveyor with variable speed form 3 m to 10 m per minute, height and location adjustment for spray nozzle is provided. spray nozzle and ultrasonic cleaner to clean nozzle parts are provided with machine. We also offer components cleaning and washing system prior to fluxing
