I recently purchased a PUK111 welder. I have a trade repair shop
doing repairs for 20 different stores. I bought this in order to
expand the types of work we were able to do as well as improve
quality and speed. So far I have been able to do several different
types of repairs; hinges next to gems that don’t take heat, posts on
earrings where heat would damage the front of the piece, platinium
hinge work on diamond links, welding a tongue into a bangle braclet,
welding several bezels onto a pendant close to gether where keeping
the others from moving was an issue and several prongs on colored
stones in yellow gold.
Most of these repairs were quite successful. However today I did a
big job where I welded several white gold prongs on a diamond ring.
I was trying to do a better job than the traditional way of using
solder and wire to make tips. The job looked good until I started
cleaning it up and found the white gold basiclly looked like a sponge
all filled with little pits and holes. Does anyone have a clue on
why this happened becaus e I don’t. I am using Argon with the PUK as
suggested by the manufacturer After smoothing and trimming up the
prongs I even went back and hit the pitted areas with a low powered
pulse to reflow the surface which looked good until I polished it on
the buffer. This machine is supposed to fill pits and fix purosity.
I’m now going to have to remove all the prongs I welded on and do
the job the old way, but I thought I’d ask you all for suggestions
Thanks for any help in advance, Mitch.
