Does anyone know if Argonite ArN2 is any good for TIG welding?? What about CO2?

Nope its got to be Pure argon

I tried to do a bit with argon /co2 as its all I had. You could do a little bit and then the weld pool would react and turn to aero bar

I tried some it made me go all weak and listless oh sorry that was kryptonite.
Cheers,

Nitrogen in welds is bad news causes brittle fracture.---

I suppose thats why they make low nitrogen welding rods
