Actually there is an internal reg, but yes, you are essentially correct. As much as I like to tweak line pressures, I have rarely felt restricted with this setup. Between 5 nozzle sizes and the mixture adjustments on the handle, the range is quite broad. Easily from .010" to .250". Maybe someday I'll plumb an external oxygen reg, but so far, I can't honestly say it'd be justified.
