Hi

Feed it down a hypodermic needle or a glass tube.

I've spent the last hour trying to put the wire into the hole in the Teflon sleeve and I can hardly see the wire with +2.25 glasses and a magnifier lamp, much less hold it steady enough to get it welded without touching something else in the meantime.  I'm thinking I'm going to have to automate it somehow.  My sight is just not good enough and my steadiness is not there either.  I think it can be done, it just needs a jig to do it somehow.  The wire is so fine any time it touches something it bends and it's magnetic too, so if I drop it, it immediately goes to the magnet.  That's probably why it was outside the copper cup when I took the end cap off.  It's almost like I need to put the whole form into the cup with the wire in place while it gets welded.  And that means everything needs to be dimensioned correctly while it's inserted.
