To work boro, you are going to need a better supply of oxygen, even two concentrators on some torches won't cut it.

Most of the newer "next generation" torches are moving towards higher oxygen pressure requirements - the Bethlehem line is an example of this - they need solid oxygen pressures of 20 PSI to operate at "optimal" use. You can certainly use lower pressures, but the factory recommendation is 20 PSI.

If you need to stick with concentrators, I recommend sticking with the Nortel line and moving to the Midrange or Red Max. Both of these torches will operate quite nicely at lower oxygen pressures and with the bigger face and more ports will generate a lot more heat.

I have used both torches and found them to be quite good little torches for working small boro and medium sized soft glass bead and sculpture work.
