The CFH Zinnstein ZS 231 is ideal for pre-tinning, cleaning and maintaining copper soldering tips in one operation. It reduces smoke and odor load and ensures a long service life of the soldering tip. Salmiak- and lead-free, packed in a practical, resealable metal can. Content: 100 g.

The CFH Zinnstein ZS 231 (Art.-No.: 52231) is an indispensable accessory for electric soldering equipment and copper soldering iron. It enables pre-tinning, cleaning and maintenance of copper soldering tips in a single operation – for clean and durable solder joints. Thanks to its special composition of pressed metal powder (S-Sn97Cu3) with inorganic activators, the tin stone is salmiak- and lead-free and reduces smoke and odor exposure during work. The application is very simple: the hot soldering tip is pressed into the tin stone with a slight pressure, which melts the solder and the tip is optimally cleaned and tinned. Delivered in a practical, resealable metal can for safe storage.
