Enough to do a 2 inch boro marble in a reasonable time? I love my alpha but I want something that is a little faster. According to its specs, the M20 should run a scorpion, but at what percentage. And how do you determine that a torch is running at 100%? Is 100% raging, just below raging, or a nice steady oxydizing flame?
The other thing I have always wondered, if you are running your tank at 8 psi, what lpm are you getting? Is there an equation to find out?
Thanks,
John
