Welding with carbon Dioxide

Why cant I tig weld steel with carbon dioxide...Also I know that each type of Tungsten electrodes have their advantages,But how would you rate them for welding (mostly steel alloys )and occasionally aluminum


Carbon dioxide is reactive. it will eat your tungsten up.

I used to use 2% thoriated for everything.

now I use 2% lanthanated for everything.

you can use this and that and some of it might work a little better for certain applications but I dont have time for all that.

2% lanthanateed works for literally everything.
