The question of how to remove the oxide discoloration resulting from
welding stainless comes up from time to time. Praxair has a new
solution, said to be safe.

I don't know anything about it but there is a brief mention in our new
magazine, _Welding Productivity_.

You're seeing that issue before the rest of the world will see it. It
probably will go live tomorrow. It's still undergoing some editing.

Anyway, if you're interested, call Praxair.

Yeah, keeping hydrofluoric acid around makes me uncomfortable. If this
stuff works well, a lot of people in the fabricating business will
jump on it.

There do seem to be a fair number of safe products, compared to
hydroflouric/nitric, on the market, at least in the UK. A company I know
uses a phosphoric acid based liquid with an electric power supply

Yeah, Ensitech has something similar in their TIG Brush. But Praxair's
new product doesn't involve electricity or the power supply and
equipment.
