I've known for a short while about cold smoking with soldering irons.
I recently went to a hardware store to choose a soldering iron for cold smoking. For goodness sake?!? There were so many to choose from. Different sizes, wattages, etc. I expected the heating element part of the soldering iron to be quite long, but it's only a few centrimetres long, at the most. Is this going to be big enough to smoke a can full of sawdust/chips? Also, one of the staff at the hardware store said some of the soldering irons have their tips "already tipped" (prepared or primed in some way), where as some of them don't. This has got to make some difference, in terms of food safety. I also read online that you should only ever use a brand new, unused soldering iron that has not been used for actual soldering.
Before I poison myself with some weird chemical smoke, can someone give me some advice with soldering irons please? Types? More/Less wattage is best? Specific brand(s)/model(s) perhaps? Any sort of metal cans (for the sawdust) that you should not use? But the main issue is getting (or avoiding) an "already tipped" soldering iron, as well as wattage.
If you post a reply in the Forums, that would be great....but please....PM me as well. Thanks all.
