With a new tip for your soldering gun, you’ll achieve better and faster solder joints, and the whole process will be a lot more simple. This tip fits all analog and digital irons, and it’s simple to swap out, taking only 30 seconds. All of the tips are suitable for both lead and lead-free environments (simply set the iron to the temperature required for the solder you are using).
