Looks like 60-75. I see nothing on my 45 guess. Like the 75, like to fill wider gaps. Plus d1.1 tube cert test shows 37.5 single bevel. Other end is square. Ain't nothin like knowin for sure...

What no attachment for hand torch to bevel us some pipe? At home practicing 6G. Got good info off this site for 1/8" root opening and 1/8" land. But how bout included angle? Guessin' 45*, for 22.5 per side. Gracias
