Thanks Dave I bought the Sparkie II from Reactive Metals even
though it is made here in MA. The problem is getting sterling
findingd to fuse to sterling- I'm applying pin findings and cuff
link joints to etched sterling items that have epoxy resin color
enamels in them for a wholesale client. I am getting burn marks
using the booster pack. Have more of the order to do and I want
to get the system down pat.
I use an additional wire to connect to the jig fixture and hold
it against the piece of jewelry I am fusing to. This further
guarantees that the electric charge will pass through the piece
of jewelry properly.
I usually get flash marks when using the booster pack and large
findings. I have heard of Batterns self pickling flux to improve
the weld on sterling, I have not tried this one yet.
I have not had success in fusing sterling posts to sterling. I
use the heavier post available and do not get an acceptable
fusion. I am open to suggestions here. I Sparkie sterling posts
on and then solder them for production work. However, for repairs
I have found that titanium and surgical steel posts work very
well on sterling. I prefer the titanium. Most customers do not
care as they just want to be able to wear the earring again.
Perhaps the thinner sterling posts work ok, but I do not use them
as I know they will break anyway.
The folks at Triad (Royal Findings) are very helpful no matter
where you bought their machine. Andy and his wife attend a lot of
the major trade shows that involve jewelers. If you have any
technical questions you might give them a call. Their number is
508-222-8173. Call and get on their mailing list anyway as they
send out a nice newsletter with tips on using their products.
These machines as with any process requires some experience for
optimal results, but it is well worth the effort.
I hope this helps.
