I'll be genuinely interested to follow your experience with this.

My attempts at TIG glueing is generally (a bit like my attempts at Thai cookery), a blind panic of trying to control 4 contradictory things at a time due to lack of preparedness and an absence of my skill (also, having a 140A arc 6 inches from my face....). Throwing an autofeed into that feels like adding a 5th random element into the mix, but if you claim it helps then I might thinking about having a pop at this myself. The cynic in me still questions whether this would have not already been invented if the need is there, but I'm sufficiently ambiguous with metal-glueing to sit on the fence with this one.

I'll break out the popcorn on this thread. Good luck :)
