In the many years that I have worked for EXAIR, I continually come across new applications for the Cold Gun.
I was contacted by a customer who makes costume jewelry. They secure the gems into their posts by soldering with precious metal. In some of the more intricate designs, the joint has to be cooled quickly before the heat has an effect on nearby posts. Using a model 5215 Cold Gun, they were able to control heat migration and in doing so they could move on to the next post without having to wait for it to cool. This increased production by 15%.
