Titanium is great stuff, but welding it can be a real pain. For starters it has to be done in an inert atmosphere (argon) and the parts have to be allowed to cool to room temperature within this enveloping gas. To make this possible I had to build a glove box, complete with access ports for torch, hands and ground clamp and the top had to be removable so that parts could be admitted and assemblies withdrawn. The one shown in the photos below was put together in a single day and cost me less than $100.
