Heatsensitive gemstones must no longer be removed from their setting when changing a ring size. This provides the goldsmith with immense time advantages. When joining the ring back together by welding instead of soldering the heat development is so low that the gemstone is not affected. The welding procedure is demonstrated using a simple ring made of 14 karat gold and the most practically tried and tested device PUK 2. www.lampert.info

Ring sizing: Exemplary wedding ring 14 karat yellow gold, 4mm x 2mm, half-round. 1_Fit the ring to the requested size and file until wedge shaped

2_Put similargold wire 0.4 to 0.5 mm into the joint, place the electrode next to the wire and melt on the material

3_Try to introduce the welding material in layers, even and tight

4_Fill up the joint until the introduced material juts out approx. 0.3 to 0.5 mm. Proceed in the same way on the back of the joint

5_The compactor has now been used to polish the joint

6_Apply high revolutions to bring the welded joint to the exact and requested height

7_The seam is trimmed or polished using a polisher or emery file
