When he said, "...Now we are doing vertical..." I assumed the "we" was the whole class.

I may be mistaken, but he seemed adamant on that point.

Yes, the whole class was doing vertical with 6010, 7018, 6013. I don't see how I could have done 6013 vertical up. The weld was very liquid and and I had to move fast or else the weld metal would pool up and fall like a rain drop. it was frustrating because I thought it was perfect, but then I chipped the slag away and there were slag inclusions. Mr. Pinckney, my professor said the machine I was on probably didn't help, and that I do too well on the new Inverters, so he has been putting me on the older machines to increase the difficulty. He is an awesome professor, and very knowledgeable. Once I get something he challenges me with new twist.

Vertical up is quite possible (and usually preferred) with 6013. It's a different animal from running it down, as you've seen, but once you figure it out, you'll wonder why it seemed so hard at first.

Sounds like you are experiencing the reverse of what I went through.
I learned in the 80's on transformer machines and kept using them until a few years ago when I started using inverters too.
They didn't weld the same and took me a little getting used to them.

Here is an article that helped clear up the differences for me.

So that's why the dig is always set to zero when I come in after the TIG class.
