Liquid Nitrogen for cooling electrodes NASA 1966

posted on Mar 26, 2022 05:39AM

Peter, I believe if memory serves me, water is the cooling mechanism for the torches.. Has your team experimented with liquid nitrogen in cooling the torches?

If it’s a viable alternative, is it worth the stranded cost of infrastructure to supply an individual torch for a given electrode extended life?

In other words, is any meaningful extension worth it?

I hope all is well.
