My question is should you turn off a solder iron to preserve tip when not in use. I am currently working on a project which requires sometimes a lot of soldering and sometimes occasional soldering to reroute wires or just tin wires to use as jumper cables. I work 8 to 12 hours a day and most of the time I am programming but sometimes I need to change things on hardware when I solder. So when I am programming should I turn off the soldering station or should I just leave it on or should I minimize the tempreture to preserve the solder tip?
You should turn it off. I see several related questions. If you want to know more, you can look here:
