Original poster: "chris carsten by way of Terry Fritz <twftesla-at-qwest-dot-net>" <ctom-at-toast-dot-net> I have a chance to get my hands on some tungsten welding rod for my tsg. The guy says he has pure tungsten and some 2% chloride. Which would be better? He also has various diameters but I would figure that the bigger the better here right? Thank you in advance, Chris
