It was plasma arc welding by a machine. Is that still TIG?
I'm not even sure my Dekerf I posted a picture of is TIG either!
I don't know much about welding!
I'm a man of many talents. I can paint, wield tools, lick my own elbow and breathe through my ears, but I'll be buggered if I'm not the worlds worst welder. Never could get the hang of any of the different disciplines, so kudos from me for those with the skills.
