passageway between the front gate 70 and front guide 78 adjustment of the slope of the exit trough 44 adjustment of the height of the weir 56 at the end of the trough 44 and adjustment of the gate 60 in the dross reduction tray 58 to control solder flow in order of removal the exit trough 44 and weir 56 are first removed then the dross reduction tray 58 the front gate 70 followed by the front plate 28 and back plate 30 these are the easily removable components of the solder nozzle and may be cleaned and replaced or alternatively replaced by previously cleaned or new units in a matter of minutes a quick connect nozzle assembly 90 is shown in fig3 to 5 which sits on a chimney flow duct 12 a pump means 112 comprising for example a conventional belt driven impeller 114 is provided to pump solder from the solder reservoir up through the chimney flow duct 12 a solder nozzle duct 92 has a shoulder 94 which in the example shown is bar stock welded to the inside of the solder nozzle duct 94 to form a location stop to position and hold the nozzle assembly 90 to the chimney flow duct 12 the shoulder 94 also forms a partial seal to prevent solder leaking back to the reservoir.
