I've been working on a portable corny setup using a Kobalt mini-regulator and paintball CO2 tank. After completion, I depressed the pin lock gas fitting and took a whiff. It had a distinct odor and that got me worried about contamination potential.
So, I walk over to my fixed corny setup with a 6 month old, 20# welding supply bottle and took a whiff from an unused gas fitting as a baseline. Same odor.
Given that CO2 is supposed to be odorless, what might I be smelling? Is it my nose's reaction to such a strong CO2 concentration or do I have a problem? Does anyone else get an odor out of their welding supplier CO2 bottle? BTW, only beverage grade tubing is used throughout.
