I want to experiment with TIG WAAM at some point, once I figure out a good way to do infinite rotation of the wire feed without tangling everything up and ideally avoiding a rotary argon seal. This may be an overcomplication, feed direction vs travel direction may not matter too much when it comes to flat deposition, but it generally seems to be important in my experience when TIG *welding*. It depends on the puddle geometry, I suppose. It's not a near-term project though, I have another machine to finish and put to work first.
