according to google, 2" schedule 10 has a 0.109" wall thickness
falls between 1/16"[0.0625"] and 1/8"[0.125"]

I just was re reading what I posted and I apologize my head was thinking sch 80 (like a ASME test) so my settings were way to hot.
One thing to also keep in mind is you can run a little hotter if you move quick, but it must also be proper.

I weld stainless, stainless and more stainless...Food Industry, sanitary process piping, vessels, whatever is needed, I like to make stuff.

Here's my take on 2" sch. 10 ss... I do a lot of this, and often in position and some of it in the mirror.
I like a dead-tight fit like sanitary pipe, with the ends beveled 35-40* about half-way through, so I can do my root as a fusion. It usually works out to 45-50 amps (this depends on your comfort and speed), and you can see the puddle quiver when you have full penetration. Most of my work allows a flush root like sanitary, as long as there's full fusion. Then, I'll cap it with 3/32 rod around 60 amps.
On the bench, however, I can do an open root, 1/16" gap, 1/16" land, and prefer to dab the root as I see the keyhole.
Unless you have a restrictive WPS, do what's comfortable.

With this one I ran the root with 3/32 gap and rod,heat at 60. Cap was 55 with 3/32 rod. I still burned through in some spots though. I tried the 1/8 rod at 75 like you said but burned through big time. After the root I let it cool to the touch
and after each stringer I let it cool to the touch. But the cap on this looks a little cold.

ive been running the wrong filler metal. Ive been running 309 when I should be running 308. : /

Okay, that is not the appropriate filler, but the behavior is going to be so nearly identical to 308 that your performance should not change noticably going to the correct rod.joshuanaaa wrote:ive been running the wrong filler metal. Ive been running 309 when I should be running 308. : /

I'm looking for proper settings for sch 10 4", using gtaw process. I have a very important test on 9/28/2021. Everything will be back purged, and I need full pen. I know which tungsten size to use, and which size filler rod. I need to know which amperage will guarantee me full pen.
