Using a Thermal Arc Fab 131 with 75/25 gas mix. I've always used 100% co2 but the Fab 131 came with a regulator that has an argon / argon mix fitting. The gauge reads in CFH, what should I have it set to? I've read 15 - 25.
Also, I have a 60CF bottle, what PSI should that read when full of 75/25?
Thanks
