I do and really like it. You don’t need to use the knobs if you don’t want to but when you get to the point where you want to have pulse or adjustable pre and post flow you’ll be happy you have them. Check out the below vid about the primeweld. He had a vid about the AHP as well. Just note they have upgraded the foot pedal since his example was shipped. The one they ship with now is A LOT better.
