Looking at TIG Depot they offer several different kits for my torch, CK17, of gas savers lenses.
My questions is for about the price of the full set of Alumina cups, collets, tungsten, etc. you can buy 1 size with the Pyrez cup. So is the pyrex worth the money, with the caveat I am mainly welding .120 and thinner aluminum and .125 and thinner mild steel. I have almost exclusively been using 1/16" tungtens, I think. I have been using the same size whatever it turns out to be...
Thanks, Rod
