Well, I was digging around on bangshift.com, found this vid where they made a 90 deg bend out of weld material.......

At the end of the vid, they state: "How to fill a large gap with filler rod, and then shape it to form a smooth looking elbow. This has no practical application, but it's excellent practice for torch, heat, and filler rod control. "
And made mention of "The Tig Button", which apparently the harder you press, the more amperage you get? This is a style I've not seen previously (that doesn't mean it's brand new though, just that I don't get out much
