Hi Steve -
     
     Well, your wave solder pot will get pretty messy, definitely smell 
     bad/different for a period of time and you will generate quite a bit 
     of excess dross but I believe that as long as the solder alloy 
     originally met the ANSIJ-STD-006 specification requirements you won't 
     introduce any metallic type contamination that would cause you solder 
     joint reliability concerns. Have fun(??), wear a mask, and let us know 
     what happens.

Good day all!
     
    This might seem like a pretty dumb question, but I was wondering if there's 
anything wrong with putting old solder paste in yer' wave solder pot? I was 
feeling bored the other day, so I cleaned out our solder paste 'fridge, and I've
got some jars of a bunch of different samples of no-cleans and water solubles 
that were played around with in the past, and I just want to get rid of them 
before an operator grabs one and uses it. They're all the same alloy (63/37) but
there are different flux types. We're in a water soluble process now, and we 
don't build missile guidance systems, just class-II stuff.
     
    I wouldn't think it would hurt anything, but I don't wanna' do it if there's
something I'm not thinking about and I wind-up contaminating the pot somehow... 
(BOY, the operations boss would have my "keester"!!!) 
     
    Any problems with doing that? I mean with adding old paste to the solder 
pot? NOT with kicking my keester if I contaminated the solder pot...heck, I 
would kick my OWN keester if I did that...heh,heh...
