Don't know about the DT software but Mach3 allows you to set up separate profiles. For Ox/fuel you don't really use a voltage sensing torch height control anyway.
In using Mach Oxy is merely controlled by the software itself.
1" A36 mild steel I use a smaller tip than most torch manufacturers call for & will pierce cleanly with about 60 seconds of preheat, cut at about 14-15 IPM, & only take about .060 kerf. In fact I use the same tip for everything 1/4" - 1" merely changing regulator pressures & IPM.
