[Diabolical Artificer]

On my cheapy the nozzle gets blocked with solder which needs un-blocking by pushing a rat tailed file down it; it works ok though.

I have a heated one, cheap ebay jobbie, which is good for de capping PCB's and other big stuff, though the tip gets very hot.

I've found braid sometimes needs a lot of heat and is a bit fiddly.

For tag board I heat the solder up with an iron and a sharp tap on the edge of the bench gets rid of excess solder. Component leads can then be unwound with the joint cold. I don't wrap the new component leads round the tags, just a 90 degree bend does the job.
