There might be a better way if your concentrator must have a constant flow. Add another solenoid valve to the outer flame oxy line and wire it so it opens the oxy side of the outer flame to atmosphere when the outer flame is desired to be off then closes when you want the outer flame on.

I use a couple of 5lpm Aireseps on the inner flame of my Mirage and tanked O2 on the outer flame. Never had a problem with either.
As shown in the link thread a foot petal is very easy to make.

PS - thanks Kbinkster for the torch info last week.
