Abstract
An installation for soldering or for heat-treating workpieces (1) under a protective gas atmosphere, includes a workpiece transportation apparatus (2), an entrance (3) into the installation and an exit (4) out of the installation, a combustion-gas or heating-gas stream (B) which is conducted separately from the protective-gas stream (S) and brings the protective-gas stream (S) to operating temperature, and comprising an insulating means (5) which surrounds the installation. A considerable amount of energy is saved in that the combustion-gas or heating-gas stream (B) and the protective-gas stream (S) have approximately corresponding heat capacities and can be conducted through the installation in counterflow.
