Hi, all concerned:
A thread a few months ago mentioned a solder station from
http://www.circuitspecialists.com/prod.itml/icOid/7307
and I bought it and a companion desoldering station from CSI, despite the
"blackened-tip problem" described in the thread.
It has taken me a while to get around to using it, and I blackened the first
tip pronto.
CSI sent me 2 tips which they had tinned, and it finally occurred to me,
while watching one of the new tips change colors as it was heating up, that
I was running it too hot.
I cranked the knob back in steps to about 11 o'clock, which gave repeatable
tinnings and wipings without color change. Then I went back and reclaimed
the first CSI tip I blackened, by repeatedly tinning it in rosin-cored
solder and wiping it on the sponge. It's fine now.
Hakko tips fit ok but need a sleeve of stainless tube to make them the same
length as the CSI tips. I used a Hakko fine tip to solder the AD9854 DDS
chip onto the AA0ZZ/AMQRP DDS-VFO board.
CSI told me that the desoldering station tip is non-tinning by design, so
solder doesn't stick to it. Hakko desoldering tips do tin, but so far, so
good with the non-tinning CSI tip.
As you were.
