Sounds like your flame chemistry is reducing the glass.

Oxygen concentrators run at lower psi than regulated tanks. Most tanks run 15psi O2 but an oxycon will usually put out around 5psi. Some are higher. What model do you have?

Here's a solution that worked for me:
1. Turn your propane pressure down to about 3-4 psi while flowing.
2. Turn your oxycon up to 90% flow (4.5lpm, 9lpm, etc.)
3. Work your colors farther out in the flame even if it takes longer to melt.

I used this solution when 9lpm at 4.5psi wasn't quite good enough for colors. Now I have 13lpm at 6psi and no more issues.
