Clean soldering iron tips for flawless solder joints: Soldering sal ammoniac stone 80 x 50 x 20 mm (Art. No. 03322003)

The Soldering sal ammoniac stone 80 x 50 x 20 mm (Art. No. 03322003) is an essential care and auxiliary tool for roofers,sheet metal workers and plumbers performing professional soft-soldering work on gutters, downpipes and valleys. When continuously heated with a propane torch, a layer of scale inevitably forms on the copper soldering iron tip. If it is not removed regularly, the soft solder beads up and clean heat transfer becomes impossible.

Durch kurzes Abreiben des heißen Kupferstücks auf dem Salmiakstein unter Zugabe von etwas Lötzinn wird die Oberfläche chemisch-mechanisch von Oxiden befreit und gleichzeitig makellos neu verzinnt. Dank seiner präzisen Maße von $80\times 50\times 20\text{ mm}$ (oft auch als $81\times 51\times 20\text{ mm}$ geführt) passt der Stein passgenau in die Klemmaussparungen der Lötgarnituren LÖTMAX und LÖTMAX Kombi. Die luftdichte Einzelverschweißung stellt sicher, dass der Stein trocken auf der Baustelle ankommt und seine volle Wirkung behält.

Thoughtful features for the rigors of everyday sheet-metal work
