Nitrogen has an atomic mass of 14.01 and Argon has a mass of 39.95. Does this mean the meter would read approximately 2.3 times more than if flowing Argon? The nitrogen being less weight than Argon.

NO as mentioned each is calibrated differently for each type of gas. You need an argon controller for argon. The read is not linear depending on what type of controller you have. Are you using a Brooks, Parker, Teledyne or Omega mass flow controller?? If so refer to they're literature or tech line for more specific help.
EDIT:
Scratch what I just said....Just re-read your thread. Your using a simple flow regulator. It sounds like its for Mig/Tig welding? It should work with C25 and straight argon. Your not measuring a mass just a volume of flow. It should work. Best to contact the manufacturer of the regulator or welder for more specific info as a general answer may not apply? Your local welding supply will have the right answers as well.

Within reason flow is flow. Yes always go with a visual test run when changing gasses. Make sure the thoriaded tungsten is nice and sharp. Dont use a dirty grinding wheel to sharpen it. It will impregnates contaminates into the rod causing weld problems. Buy a dedicated rod sharpener or use a fresh wheel. You should be OK with the stock flow meter with most gas mixes. Do inquire at Miller or Lincoln just for safety as I dont know all.

It shouldn't be a prob, I do the gas juggle all the time. Just dial it in until your makin bacon. The best tool Ive purchased in a while is the Miller 211. Auto-Set the dam thing and go, takes most of the guess work out of the equation. Runs a tight bead even on 120VAC.
