Sorry but I an too far north. If you have ever put a root in Carbon pipe,, then SS will be no problem. The purge setup is somewhat of a hassle but can be worked through.

Things to remember

1 Stainless stays hot longer than carbon, the puddle will sag easier. Keep the couplon cool.

2 Set your heat before you tack, adjust it as you like on each tack if you have too.

3 If you see a little spot swirling on you puddle whan you are putting the root inb, you are probably doing a good job, leave the wire in and keep on going.

4) If you see a line from the outside of your root that looks like a creas through the centerline, you broke the walls down well.

5) The second pass over the root CAN change the root. Keep the purge on and dont stay in one place too long.

If you were in North Mississippi, I could help you out.
