I personally suspect it as a joke. I have used oxy-acetalene quite a bit.Both to weld and cut and I just can't see that setup,even with acetalene only and any 'special' regulator and torch cutting as clean as a plasma. I'd have to see it to beleive it. But with modern technology being what it is, it may be. I have used acetalene torches and they do cut, but not clean. It has to mix oxygen in ,out of the surrounding air to cut . So I would immediately wonder if it would cut anything thicker than 1/8 in.
