What is the difference between “HOT SPOT” and “SPARKEY” and why
would one choose to use that system over a soldering torch???
Ah, just read that one may not have to use solder with the above
. . . fusion then?
The Sparky(II) is a finding fusion welding device that is VERY
handy (We call him Mr. Sparky). You can fusion weld posts on
earrings with stones in them, use titanium posts, fuse pin back
It does things that you would not want to do with a torch, but
it doesn’t, by any stretch of the imagination, replace a torch.
