Orion by Sunstone Welders

Sunstone are world leaders in mciro welding technology supplying power cell manufacturers, aerospace companies, automotive groups, orthodontists, dental labs, and electronics manufacturers and of course jewellers and watchmakers.

Their ORION range has been developed for jewellery and associated applications and offer a comprehensive range of both Pulse Arc and Laser welding units to suit you space and budget. So whether you are joining precious metals, stainless steel or even titanium, why not consider an Orion.

Pulse Arc

As the name suggests, the system welds or fuses the components together with the application of a very concentrated point of energy, electrical current arcing from a probe. Pulse arc is great at really fine repairs such as re-tipping, even when stones are left mounted as there is no need to heat the whole piece. Re-sizing of rings takes seconds.

Laser Welding

Laser welders have 2 main advantages over Pulse welders

If you can see it, you can weld it – as long as the light beam can get there, you can weld.

Longer seams take less time to weld and the non-contact nature of laser welding means that manipulation of the work piece is entirely free, no grounding wires to tangle or move.
