Solder Fountain Level Gage

A solder fountain level gage uses electrically conductive probes contacting electrically conductive solder to indicate the level of solder in a solder fountain.

As indicated in the Figure, a gage 10 is positioned in a solder fountain 12 to measure the level of solder indicated by a line 14. The gage 10 has a power supply 16 such as a battery having a positive side connected to a plurality of loads 18 and neon bulb indicators 20. The negative side of the battery 16 is electrically coupled to a pair of conductive side rails 22 and 24 which support the gage 10 in the base of the solder fountain 12 and electrically contact the solder.

A number of probes 26, 28, 30, 32, and 34 are coupled electrically to the indicators 20 and adjustably supported by a nonconductive rail 36 which in turn is supported by side rails 22 and 24. The probes are of different chosen lengths so that when they contact the solder, an electrical circuit is closed causing the indicators to light up. In the Figure, the indicators coupled to probes 32 and 34 will be lighted.

Adjustability of the probes is provided by set screws 38, 40, 42, 44 and 46 which are threaded into rail 36 and have heads contacting the probes to secure them in place. Probe 26 is adjusted to a height to indicate an overflow condition which may cause damage to the solder fountain.
