TIG electrodes are Tungsten, not Titanium. I just happen to work in a Tungsten Mine. BUT, Tungsten IS a perfect metal for shafts too, It is Inert, and has the highest melting point of all metals. Won't corrode in SW. Just make sure you use PURE Tungsten Electrodes. Most electrodes have other stuff in them, like thorium(lightly radioactive)

Zirconium, Lanthanum, etc
