@Felthry I'm only opposed to *repeated use* of cheap hardware store soldering irons. One-off use when you've got nothing else to work with? That's fine.
@LexYeen i mean if it's your only option and you need to solder something by all means, but do get a proper one as soon as you can
you don't even have to go with a $100 one (which is still a fairly cheap iron, these get expensive if you want the highest quality); hakko sells the FX-901 for $30, though it's a battery-operated iron with all that that entails, and there are only two tips available for it. it is temperature controlled though
-F
@Felthry I'd be operating on the assumption that, if one has a sudden urgent need to solder things and lacks the proper tools, there's likely going to be a need to do more soldering under better conditions in the future. ;)
