Further comments This sliderule is officially named "67/56 Schweisstechnik, System Titscher". It is very rare an developed for welders.

I have not found out yet how it works, but the special part of the slide rule is the small extra scale on the front of the slide, as well as the many different formulas on the back.

The slide rule is very dirty, most likely because it was used in a metal workshop!
