Quesiton on propane purging :)

[jinu117]

Figured I should give this one a shot (I do nitrogen purging) as it is supposed to also aid in heating up the evap :) One question is, when you are done, how do you let it cool down? Do you just let it sit there for 30 mins or so with propane still burning after you are done?
It seems very interesting thing to give it a shot :)

Purging doesn't aid in heating your work piece up. Just stick with Nitrogen purging and let the nitrogen flow until the copper has cooled. 10 - 15 minutes should be plenty enough.
