Phil,
We use RMA solder strictly for tinning Metcal Tips, it has worked well
prolonging tip life. A .125 dia. helps so our operators do not mistake it
for anything else.

Based upon hour comments Steve, it sounds like this would be true for most
soldering tips regardless of manufacturer.  I'll have to pay closer
attention to tip life here.

Hi Lou!

No Clean flux is actually the worse flux to use when you're talking tip
life. Go to:

http://www.metcal.com/tips/1.3.2.htm

There's so little solids (it's mostly alcohol) that it flashes off the tip
and doesn't protect the tip the same way a RMA does from oxidation. I think
you'll find that you will go through more tips soldering with no clean
fluxes than you do with any other flux type.

TechNetters, I've noted with interest the discussion of Metcal and other
soldering irons over the past few days.  A question has come up here about
care of Metcal tips.  We've gone to some lengths to eliminate RMA flux from
the plant.  However, Metcal recommends tinning tips with RMA-flux wire
solder.  We would like to use no-clean flux to tin tips.  How risky would
such a practice be?  Any comments would be greatly appreciated.  I called
Metcal for advice and found the people I talked with to be very pleasant
and eager to help.  But no data were available, and, frankly, the people
sounded very youthful.  Lou Hart
