[sdiy] solder beads?! 8^p

[Bob Weigel]

Not sure about that model.  I have various tips here but doubt they fit 
that one.  It's probably just a plug in pen?  But anyway yeah the 
coating will wear off and the ferrous stuff will rust.  You have to keep 
tips tinned for maximum life and a wet sponge helps remove stuff that 
can burn into the tip's coating. 

The problem..I mean you can make a copper tip but it won't last long and 
will bend really easy :-).  So they designed tips that have more 
durability and that don't weaken with temperature but which 
unfortunately tend to oxidize.  And then plated them with a layer that 
will bond well with solder but will eventually react with stuff.  So 
take care of your tips.    Here is the list from my website but I don't 
know if any of those fit that thing.  Your research project :-) -Bob
