    Argon Gauges

    Is there any difference in the round style gauges flow meter gauges vs the vertical flow type other than form? My Miller came with round and my new HTP has the vertical.

    The round gauges are not flow gauges, they are pressure gauges.
    They have a face that is printed to indicate flow at a certain pressure.
    That is fine until you change anything in the system(hose or fitting size, torch size an even hose length) that they
    were verified with then they are no longer accurate.
    The vertical flow gauges are the only true flow gauges. Since the flow is measured in the vertical column you can
    change anything in the system and the vertical column will still measure the flow accurately.

    By the way I have worked in the pressure measuring industry for 40 years.

    Thanks for the information. I assume that repacing the pressure gauges with an actual flow gauge will be no problem.

    pressure gauge on my Mig set up
    Flow on my Tig.

    No need to replace the gauges.

    Thanks. Moot question now. Sold the 211 and replaced with the HTP Pro Pulse 220 MTS.

    The mig uses gauge but it is not the same as a standard pressure regulator. It is still a flowmeter. It has a small metering orifice in the outlet that allows it to expel what you set on the CFH gauge. The downline restriction doesn't change it much because the orifice restrictor is way more resistance than anything after it.

    You do not want a column type on a mig because to set one you have to be flowing gas which means triggering the gun which isn't practical when it is spitting wire out.

    The gauge type is what you want on the mig.

    A regulator and a flow gauge regulator are very different in how they work and what they do. People often are confused by the differences.

    This is a regulator and works like one on a air compressor turn it up and the PSI goes up.

    This is a flow gauge regulator and more suited for a mig. The flowmeter type is for tig although could be used on either just like the gauge type could be used with Tig also. Best for mig because you can adjust without have to flow any gas and the wire that would be coming out.
    It measures the flow by backpressure created by a tiny orifice to make the CFH reading pretty accurate.
