You are correct, sir! A Sparkie is a fusion welder used to
attach findings without soldering. You have to use special
findings that have a little “nib” on them that actually melts
and fuses the two pieces together. I was somewhat skeptical at
first, but had the opportunity to use one at the community
college a couple years ago. I was probably the only person to
have ever used it!
The area where the finding it to be attached has to be pretty
flat. The only pieces that had any trouble were the pieces I
did that didn’t conform to this rule. Even some did pretty well
that weren’t flat but I was able to get a good conductive
It can (does) leave a little bit of a burn mark in the immediate
area of the weld, but that is relatively easily cleaned…
especially compared to boric acid, flux, solder, pickle, buff,
polish, etc. For the right situation, it would be a real
time/money saver… especially in a production environment.
The Sparkie II (has more collets and features than the original)
runs over $1000, so I’m looking for a used one. I’m not
currently in a production environment, and it would take lot
longer for it to pay for itself. I am considering buying one
new if I can’t locate a used machine. Probably get it from Bill
Seeley at Reactive Metals (a plug, but I have no association…
just like to see the little guys win sometimes).
