Anyone using a GTT with compressed air option?
The title just about sums it up--I'm saving up money for a GTT Phantom (I want triple mix after seeing it used to make the kind of sculptures I want to make), and I'm wondering if their new compressed air option (compressed air in addition to the propane and two O2 studs) would be worth the extra $. The marketing claims sound really good, but I can't find any reviews--I'd love to hear from anyone who has first hand experience with a GTT torch (any model) with the compressed air option.

I tried one and didn't notice any difference. GTT's are so easy on color anyways that I really don't see the need.

Thanks Cosmo--I actually had a lot of trouble with colors reducing (when I didn't want them to) with my bobcat, but a new oxycon helped a lot with that.

Guess they haven't sold many, at least to LE members. Thanks!

It's the concentrator, not the torch. When you run concentrators at higher flow rates, the oxygen purity suffers. That's why you are getting better colors with two concentrators.
