Jason, When I first started out trying to solder electronics, I practiced on junk electronics, I would uninstall capacitors, diodes, switches, wires, etc. and then solder them back in place, improving technique and speed with practice. After a while you get better and faster and will find a temperature/ setting your comfortable with. For me I found setting 4 on my iron approx. 700 degrees allowed me to unsolder and resolder with out damaging/burning parts. I am by no means the best soldering person in the world, but have built up confidence to tackle a lot of soldering applications just by practice. The same with different tips, just experiment and you will find your favorite tip for different applications. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.
Temperature Gun, Non-contact Digital Laser Infrared IR Thermometer can be found by google search if you desire knowing more precise what heat output on different settings are on your Weller WLC100.
I am extremely sorry. It is a WLC100. I will edit my original post.

If for some reason you did need to know actual temperature a Tempilstick or similar product should work.
As you do more and more soldering you'll get used to how it's done etc. and you'll be able to set the temperature which gives you the best results.
As always soldering is a compromise between the speed of soldering , good joints and not burning the flux away too quickly. The type of soldering you are doing will also effect the temperature ...I've found that working on vintage equipment requires a slightly higher temperature than doing new soldering and if you use lead-free solder you'll need a higher temperature again.
So it doesn't matter about the degrees not being marked ..just find out what gives you good results and then put a little mark on the setting so you can always go back to it.
I thinks that's one of the reasons why people like the old Weller TCP soldering irons, you just change the bits to adjust the temperature - all the worrying is removed and it all becomes simple.
