Tony,
I? had a similar problem with a cheap soldering iron from China. Out of frustration, I decided to disassemble it, and I? found the cause of the problem. To save money on the world market, the 120 and 220 iron uses the same components. Two 120V heating elements that are wired in series for 220V, and in parallel for 120. So I? received a 220 iron with a bad labeling.

For soldering SMT components Just apply it to the spot & pads, the flux helps hold the part to the board and the flux obviously helps the minuscule amount of solder fix the part. It also helps with desoldering, apply it to the part and either use the wick or tweezers to remove it.

I thought I'd also mention picking up one of these some time back when I was in a bind, did not have a lot of extra funds, and needed something besides solder wicking and/or solder plungers, neither of which I have had very much luck with over the years:

The motivation behind this was a cracked slug when I was attempting to retune a bandpass filter in a rig I've been trying to tune up and align.? Only way to remove the slug was to desolder the bandpass filter and I knew wicking/ plunger wasn't going to do it very well.? Well, the above device took about 6 weeks to arrive, I tapped into my 220 VAC lines, and the device ensured success.? Keep in mind that it's quite crude compared to much more expensive desolderers and may take several tries (orientation and heating have to be exact), but it works.? My advice would be to keep it activated as solder is removed from a joint, then release over a trash can/ towel, etc otherwise solder flies right back onto the board if you release it right away.? And you don't want it to remain activated too long as I believe it uses a electromagnetic coil which could get hot quickly.? I try to use a duty cycle.
Not a bad little device for the price, however.
Jon
