desoldering iron Answered

i am thinking of purchasing a desoldering iron, because braid gets annoying, and i was looking at one at radioshack, its just a soldering iron with a hole in its end and the hole leads of a mounted bulb. i was wondering how they work, the iron heat the solder, and u press the bulb and it sucks the solder, but where does the solder go? into the bulb? how do you get the solder out?

i desolder by heating the joint (and maybe adding a bit of solder) and then hit the board (not too hard) against the floor gives very clean results same with compomemts - you drop them from small height and the solder splashes off

Yes, but what about snapping said flaming red piece of lead off and landing on say your head. Poof goes a big patch of hair.

you hit it down and not up. it cant get to your head the bits of solder that splash off are tiny. so tiny that if they hit your hand they cool down and not burn you

well, in my opinion, yes You can burn yourself very easily with the de-soldering iron, because of all the exposed metal. Also, when you squeeze the bulb and re-lease, is sucks the solder up and releases it to the same place it was extracted from solder suckers have plastic tips, which melt fairly easily

mine doesn't melt. We're talking about the spring loaded metal things, right? I love mine, except whenever I need to put a lot of flux on a joint to melt it and then it sucks up all of the flux and then it's a pain to clean the insides

You should get a separate mechanical solder sucker, spring-loaded pump action. I guess those rubber bulbs ones will also do the trick but they seem to have less suction and they blow out when you squeeze it to get ready to suck solder. You pull the tip off to dump out cooled solder shrapnel. The times you need to desolder would not really pay for a dedicated desoldering iron and the separate solder sucker is handy always ready without having the need to fire up another iron if you are already soldering. I think you can manipulate separate tools better too. Good luck.

Wise post is wise. I've always used braid, but if I ever turned down this path, this is what I would do.
