[Elecraft] Off Topic (solder pot)

[arm at uniontel.net]

Hello all, I have been building a K2 and now a KPA-100. I am using a solder 
pot for tinning toroids and would like to know how often to replace the 
solder in the pot. I have been skimming the top which removes flux and 
debries. I used a 1/2lb off a flux core roll and found it contains too much 
flux on the top, so I skim the top as it is heating to leave a thin layer on 
the top. Should i be reintroducing more flux as I go, and should I be 
removing the burn't enamel some other way? Also what temp works the best, 
this thing smokes pretty good at 750*F and seems to burn the flux. Anything 
much less and it won't tin properly.
 
Thanks -- Rick
