A 20 cu ft bottle that is for a MIG welder. Need to buy one for a new Millermatic 175, but don't know if I should go with a 20 or 40 for use at home.

Not long at all. I started out with a 20cf and it didn't last long at all. I ended up trading it in for a 80cf.

Get the biggest tank you feel comfortable moving around.
