Can you explain that? Basically, why would a person want a 4 stud?

If you want to run a foot pedal, then you would want 4 stud.
On other torches, it's a good idea to have 4 studs so you can run the centerfire and outerfire on seperate oxygen sources if you had to (like the center on a concentrator and the outer on tanked). The Scorpion runs so well on concentrators for both fires, you really don't have to have the four studs unless you have mis-matched concentrators that cannot be hooked up to run together and you want to use one on the centerfire and one on the outerfire OR if you want to run the outerfire with a foot pedal.
