The concentrates are all combined into one manifold. One could use "Y" connectors to perform the same function. Then two oxygen lines are run to the torch as it is a 4 stud unit.

When the torch is on, oxygen is added to the outer ring as it help better form the inner flame. Then when additional heat is needed only the fuel is added and adjusted as needed for the outer flame. The O2 is always on for both the inner and outer flame.

The Scorpion works very well with three 5 LPM units. Like to keep the overall O2 in the 3.5 to 4 LPM range on each machine. The Cricket will work with one 5 LPM unit, but will perform much better with two concentrates.
