What didn't you like about the Tack II and Tack III. Also, what
kind of Laser Welder did you buy?
I did like them but we were have lasering done by someone else and
thought it would be more efficient/expeditious to have out owm.
TackII is great for putting heads etc.. together before soldering
TackIII is really great for jump ring soldering - I did things like
repronging of platinum even with emeralds, using small piece of mica
to protect the stone
