You need a low pressure regulator (red) set somewhere between 5 and 10 lbs. Start low. I would get some of the flexable exhaust pipe you see in auto parts stores and get rid of the plastic. I think it's 2 inches X 24 inches long. When you get it to where you can change the pressure and air flow, you will see that it can be "tuned" and it will get hotter faster and make it's own unique sound. I listen for any changes in the sound while forging. This let's me work while being aware of the staus of the forge without having to literally watch it.
