ER80S-B2 and chromoly

What is everyones best recommendation for welding 4130 chromoly tube w/.035-.120 wall thickness? Lanthanated...what's everyones results?

I'm referring to the tungsten of course.

1/16" diameter would be a good size.

1.5% Lanthanated will work fine, and are fairly common.

2% Thoriated will work, and are even more common.

Ceriated tungstens will also work
