Well, Dr Pipe, here in Chicago our WPS states, 6010 root and can run that out if x42 and lower or 6010 root and run 7010 out up to x70. We don't have anything stronger than that. Really don't need being MAOP is 450. Population density dictates that, but out in Gods country, 1000 and up is the norm.

We do use 80s d-2 in our mig guns. Were a little behind the times, still running the 19th edition API 1104.

And not to start anything, but, all the pipepros that came through for quailification passes, can't say that about the Lincoln's, here. I know alot of the older guys love them salamanders, but after running mine, I'll never go back. Darn shame they stop building them!
