Sigma's technology originated with friction welding, not wire, right?

That's crazy-- I mean closed loop control with wire-feed (like in welding) is literally our patent....not to mention our oldest tech/what we've been doing the longest/ something we've actually sold.... [all those closed loop weld pictures in their papers, the 2011/12 work...] and didn't Mark say we were working with a Phillips? Hmmm....... Idk what to think about this.
