You might try using the stick welder. The flux on the stick rod might do enough to get rid of the carbon and crud. Tig uses gas to prevent carbon and crud, but the flux gets rid of existing crud.

Forgot to add. You might post over on SJEW and get Ernie's advice. He likes some of the ESAB consumables, but not the ESAB welders. And ESAB has a rod for welding cruddy cast iron. May or may not be the best.

ESAB has some good specialty rods, and so does Hobart. Ernie would be
a good first stop but don't overlook just calling those companies and
talking to an engineer or tech specialist. They're there to help and
they live with issues like that every day.
