Hi Lawry, I work on electronic circuits for a large variety of things and Im all too familiar with the crumbly vaporized solder crap due to my iron overheating towards the later end of its life. Thats the main reason why I prefer temperature controlled irons, as well as to prevent the horrid melted pcb board coating smell that comes with an iron thats too hot and touches the green pcb board coatings. Controlled irons are also great cos it allows me to use lead free solder as well which is a tad harder to melt. Gas powered irons seem pretty cool though, cos the wire free tool has great appeal to me.
You make some very good points here, mate. Also, the eutectic temperature for lead free solder can be 20-40 degrees higher than 'standard' tin/lead solder. And it's also best that you don't mix the two types together when soldering as cross contamination may leave you with a dodgy joint unless you're very careful.
