32 cfh is not the right number. Here is the problem. We need a flow meter, and nitrogen regulators do not have one. Therefore, we have to get an argon regulator since they have flow meters. 32 Cfh is the right number for Argon, but not nitrogen. Argon is 44% heavier than Argon, so we have to compensate for that. I am horrible at math, so I do not know if we need to set the flow meter 44% higher or 44% lower than 32 cfh. Hopefully, chronic pain no more or someone with better skills can help us.
Regarding the max dog regulator, do not buy it. That regulator is no better than $25 regulators on Amazon. He insanely overpriced it over 10 times what it was worth. I do not support anyone who takes advantage of people like us....absolutely disgusting. We can get the calculation easily and the hose can be bought at Home Depot or Lowes for $5.
