I do keep an assortment of tips around; I think that the "one that 
comes in the box" is a PTA7, but for fine 63/37 SnPb solder, 700F is 
just too hot.  I don't particularly care for RoHS solder; 
fortunately, the leaded stuff is easy enough to obtain in the US.  It 
might not be the case in the EU.

The last bit of plumbing I did (replacing a well pressure tank) was 
done with 50/50 solder and it's the solder that I use when working on 
brass musical instruments.  It stays "plastic" longer than the 
eutectic variety (which has virtually no plastic phase) and can be 
tooled while still soft.  The amount of lead-bearing surface exposed 
to the water supply or musician is very small if things have been 
done correctly.

But since "plumber" comes from the Latin for lead, what does one call 
an RoHS pipefitter?  Stanner?  Indier?
