... also we never change gas pressure unless we are running co2. Argon oxygen welding is usually set at 40psi...


I usually run mine at about 20psi, 75/25 argon/co2. But I also have no moving air in my garage where I do my welding. If the doors are open and there is a breeze I'll crank the psi up.
