which includes a frame 73 and carriages 74 and 76 translatable on the frame with the carriages carrying the respective sectors the translation of the carriages on the frame serves to vary the distance between the pivot points of the nozzles and the plane of the near horizontal transport system it is a finding of this invention that the greatest efficiency in the removal of solder from holes in the printed wiring board is achieved when the top nozzle is angled at or near perpendicular to the plane of the printed wiring board and thus substantially perpendicular to the near horizontal transport system plane whereas the bottom nozzle is slightly angled towards the solder pot as indicated as much as 25 u00b0 from the perpendicular to the face of the printed wiring board alternatively the bottom nozzle is angled at or near perpendicular to the plane of the board with the top nozzle angled towards the solder pot as illustrated solder pot 30 is a recirculating type solder pot which by virtue of pump 80 and impeller 82 pumps solder generally indicated at 84 up into a standpipe 88 whence it flows out through throat 32 and over the edge of the throat down into.
