When I'm running my Smith Little Torch off my propane and concentrator, I set the propane at 3 and the oxy at 4.5-4.75. If you're not used to lighting the Smith, back your propane way back at the torch knob to light, and then the oxy. Gradually turn both up til you get the flame you want. If it pops and goes out, turn them both off and try again, only turn them up even lower to begin with.
