As promised here is a view across our workshop area, which you can see when you come into our jewellery showroom in Preston CIty Centre. This is bench number one. This is where we do the "PUK-WELDING" on silver, gold and platinum. PUK welding is a miniature form of TIG welding which uses Argon gas (Which is an inert gas). The tiny Tungsten carbide needle on ths machine can be seen through the microscope. A current is passed through, literally for a few milliseconds, and in a flash you can join metals together. Underneath the picture below you can see a brief video of this piece of equipment in action.
