So, you may be asking yourself,
“Why welding for Jewelry makers?  I’ve never needed that before.”
Welding with a PUK micro-welder enables tasks not possible with a torch flame.  Some examples are:
  • Spot welding areas to keep sections in place – as in forming a bezel around an odd shaped stone
  • Adding metal, filling porosity, and closing gaps and holes with perfect color match
  • Welding delicate pieces such as filigree or other items that are very thin
  • Re-sizing rings & re-tipping prongs without removing stones
  • Joining metals not possible or extremely difficult to braze or solder, such as stainless steel or titanium
There will be hands on time!  Bring at least one sample or project that involves situations such as these:
  • Closing a hole or filling a gap
  • Filling pits or dents in cast pieces
  • Attaching a finding or a small or thin piece to a large one
  • Closing jump rings or chain links (open, NOT solder filled)
  • A repair next to a heat sensitive material, or to avoid annealing (a broken chain, clasp, etc.)
  • A prong setting
  • A hollow form, with two or more matching or fitting parts (i.e. 2 half spheres to make a ball)
  • Any other metal besides sterling that you work with or that you’d like to try -sheet, wire, tubing

The PUK has pre-sets for gold, silver, platinum, palladium, stainless steel, titanium, brass, aluminum, and tin, and a universal pre set to work with other metals such as copper, carbon steel, etc. Mariana will also have a selection of metal samples to play with.
