Re: Used Parts Build
I wouldn't expect TIG to go through much more gas than MIG. 15-20cfh is a pretty common flow rate for each. About the only way for a similar size MIG bottle to last a lot longer is if it's CO2 (a 20lb CO2 bottle is around 170cf while a similar size C25 or Argon bottle is around 80cf). Of course, it does take more time with TIG so you get less welding done. If you're doing much welding at all, buy the biggest bottle you can reasonably store.
Too bad you had to cut it off.
