ABSTRACT:
Automatic wave solder apparatus in which printed circuit boards are passed over a wave soldering section to apply solder to exposed metallic surfaces on the undersides of the surface of the board. A weir is attached to the exit side of a discharge nozzle for the solder wave which is spring loaded upwards for engagement with a stop member. The solder pot assembly may be lowered and swung out of a circuit board conveyor path for cleaning and both front plate and rear plate members on each side of the discharge nozzle are hinged so they can be raised for cleaning when the solder pot assembly is lowered. The stop member permits the discharge nozzle to be raised to different heights, but retains the spring loaded weir at the same height.
