The M12? soldering iron delivers fast application speeds by reaching operational temperature in under 18 seconds and maintaining an optimized temperature throughout the most demanding applications. The heat indicator utilizes REDLINK? Intelligence to notify users when the tool is ready-to-use and safe-to-store, eliminating the guesswork. The 3-stop pivoting head provides unmatched access by allowing users the ability to adapt the tool for the application and solder in more confined spaces. The M12? soldering iron powered by REDLITHIUM? battery technology delivers up to 40 minutes of run-time on a M12? compact battery pack.
