Ugh, I'm with you but don't ever make the mistake of repeating this in front of old dudes that played with CB radios in the 70s unless you like pointless tirades.

Yeah in general I agree, that's the way it should be.  But like I mentioned earlier, I have a BIG roll of old rosin core solder and I guess the rosin has broken down or dried out or something...  "lost it's kick" and doesn't flow worth a darn on it's own.  A little flux and it's good as new.  But most people probably don't have 15-20 year old rosin core solder lying around I guess...  ;D

I probably should just chuck it but I hate wasting stuff.  Now, if i was doing a big solder job I wouldn't mess with it because it would just be a tedious waste of time if I had to do more than a few joints.  I guess I could just melt the whole thing down in a solder pot and use it for "dip tinning" or what have you...  I've never done things that way, but come to think of it I believe I've been told that that's actually an effective way to tin a ton of wires quickly rather than doing them one at a time with an iron... makes sense...

My solder is old, and somewhat dry, which is why I use extra flux.

I never really use flux either. I just pre-tin the tip as well. I want to test out using flux though so I can see if it will produce "prettier" soldier points for me since aesthetically my soldering is hit and miss.

Mysterioii:
If you want to try it I recommend getting a non-reactive little squeeze bottle with a teeny tiny but non-sharpened needle tip like this one...

The one I got was a bit leaky around where the top screwed on though, so I wrapped it up with teflon pipe tape.

By the way when people refer to tinning the tip that really just refers to getting a nice shiny non-oxidized coating on it, which is great, but if you really want to get good heat distribution that's why you get a little tiny pin-head dab of solder on the iron before you tin the wire.  It increases how much surface area of the wire is in contact with the heat and really improves heat transfer.  I guess it's kinda the same thing but to me it's two separate things.

I hear you. We used to ride the old timers who always had flux tins in their arsenal even though there were cases of rosin core solder in the parts department.
