General DIY Soldering Questions

Having been intrigued and swayed by a number of folks doing DIY electronics projects, I'd like to give a few a go myself. I have not used a soldering iron in about 30 years (no electronics-based experience) and seek some advice. I do plan to buy a couple of cheapo kits first to hone a few skills. Before doing so, I respectfully seek answers to the following questions:

1. While likely a matter of personal taste, is there a consensus on which soldering iron to buy for electronic use(wattage, tip style, etc.)?

2. Is there a solder of choice for most electronics applications?

3. I know from memory that things must be very clean and that flux was generally used. Is the flux contained within the solder sufficient or do most of you use additional flux?

4. I assume rosin-based flux solder is preferable. Yes? No?

5. I recall my grandfather using copper (I think) heat sinks to protect surrounding areas while soldering. How big of an issue is this?

5. What are the myriad questions that am I blithely and that should be answered before beginning?

Thanks

I would suggest doing a google search for soldering techniques, as there's a bunch of good info, i.e.: http://www.elexp.com/t_solder.htm

I prefer a pencil type soldering station, as the pencil is easier to hold than a soldering gun. Also, I like a temp. controlled model. I use a Hakko 936-12 but there are many others to choose from. I also like Cardas solder, as it flows easily. Again, many good brands to choose from.

The main thing I can suggest is to tin the tip & use a wet sponge to clean off the tip on a frequent basis. I would also suggest practicing with some scraps before starting a DIY project.

I always use heatsinks on everything other than cables. You can even use a small pair of needle nose pliers w/a rubber band around the handle to keep a grip on the wire.

Have fun!
