Pace Worldwide has been making soldering equipment since 1958. They recently put their videos onto YouTube:

Most interesting are the Basic Soldering Lessons 1-9 and Rework & Repair Lessons 1-8

If you've never soldered before but want to these will get you going. And unless you're a professional engineer you'll also pick up quite a few tricks along the way.

Great for the nostalgia, too, having been made in 1980.
