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.


20-25 cfh in a small shop with no breezes.
In a drafty larger shop 25 - 30 cfh

Also, I have a 60CF bottle, what PSI should that read when full of 75/25?

Thanks

A full tank runs around 2000 - 2300 psi.
