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

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

A full tank runs around 2000 - 2300 psi.

Hmm... hope that I've got a partially full bottle then, otherwise my
regulator is bad. It reads under 1000psi.

Any way to tell? How heavy should a full 60cf tank of 75/25 be? I can drop
it on my scale and that should tell me, I suppose.

Thanks

The weight barely changes with pressurized gasses..
Take to a supplier.
They can verify the content pressure with a known regulator.
