Jerry:
I'd be very reluctant to use a soldering iron tip cleaned with sal ammoniac
on electronic equipment. For some manufacturers, it will void the warranty.
I do not recall Elecraft's policy on sal ammoniac, but I'd check with them
before using a soldering iron tip cleaned with sal ammoniac on Elecraft
products.

I get the reflector in digest form and did not get to read some of the
past week's input until this morning...There is a chemical called "sal
ammoniac" (ammonium chloride)...It comes in small white blocks and is sold
in hardware stores and tin smith supplyers...I have a block that is
probably 40 years old...Sal ammoniac is used to tin soldering iron
tips...I use my Hakko 808 quite a lot for stripping and tinning the enamel
coated wire in toroids, so the 808 sits cooking in the holder for
hours...When my 808 tips start to discolor and reject solder, I re-tin
them with sal ammoniac and they are restored to as good as new...These
tips are QUITE expensive and we don't want to have to be throwing them out
when they are still useful...
Soldering iron tips and de-soldering tips are usually iron plated copper,
and they are factory tinned near the tip only...Sometimes the iron coating
becomes discolored and will not tin anymore...Filing it will remove the
iron plating and ruin the tip...This is where sal ammoniac can be
used...If you are not careful, it will tin the ENTIRE tip, even the part
that was not factory tinned...
