Argon Flow Rate Conversion on Tig Calculator

[Buggy Chief]

Thanks Jake98. I just found the conversion calculator and you are correct. 15 cfh converts to 7 lpm.

Thanks again for your response and help.

Hey, no problem, I've got at least two hours tig experience now! (one per tank full..)

I was disappointed myself because on the phone with the salesman before I ordered, we discussed the difference between the everlast tig machines and the Miller ones. I mentioned the metric flow meter and I was told that the flowmeters are not calibrated in metric. When i recieved my unit, i found out that was clearly not true. And the funny thing is my manual from everlast mentions a CFH measure, not a metric one.

~3.8 liters per gallon

7.48 gallons per ft^3

60 min per hr

1 [ft^3/hr] = X liters/hr can be calculated as follows


1 [ft^3/hr] * 7.48 [gallons/ft^3]*3.8 [liters/gallon] = 28.4 [liters/hr]

Because there are 60 min per hr the 28.4 liters per hour can be divided by 60 to provide a conversion from CFH to liters per minute (LPM).

28.4 [liters/hr] /(60 [min/hr]) = 0.47 LPM = 1 CFH

With this number 0.47 being so close to 0.5, just divide the usual CFH by two and this will provide a close conversion for LPM to use for a setting.

I.E. 15 CFH ~ 7.5 LPM or 20 CFH ~ 10 LPM.

Hope this helps save some gas.
