Soldering is often a challenge when you only have two hands. Having another person offer a third hand usually just results in someone getting burned. Ben decided to not only flip the solution (a third hand to poorly hold the object) and have the soldering iron held stationary. This solution worked great but for all the parts and setup it needed to scale to be useful. Hence the multi station solder… station. Complete with lights and fume extractor.
But you don’t always need a soldering station for a group of people. Sometimes you just need a soldering station that can hold the soldering iron for you.
