    Default amps/voltage ???

    I have a question;the below quote is from the MM212 info on the Miller site.

    Seven taps provide wider welding range of 30-210 amps with improved high and low ends to weld materials from 22 gauge up to 3/8 in (9.5 mm) thick in a single pass.

    Why is this control that selects the 30-210 AMP range labled VOLTAGE? This does not make sense to me, can someone explain this.

    Just like it says, this range of "Voltage taps" is providing for a wider "range of amperage" which you access using the wirespeed dial. I hope that makes sence.

    simple answer is the taps chose the volts then you increase or decrease the amps by the wire speed adjust.
    FWIW; many find the MM210/212 very easy to set and use. wile i have not used one much i did get to do a little 22gage on some floor boards and it worked great. if you are considering getting one, by all means get it.
    thanks for the help

    Amperage is driven by voltage. You select the voltage, and then you adjust the amperage with stickout and wire speed.

    GMAW is a Constant Voltage process.

    thats why its so important to lern to keep a constant stickout, it plays a big part in the process. you need to be able to controle it.

    Thanks for the info guys.

    Sundown when you say it like this: range of "Voltage taps" is providing for a wider "range of amperage" which you access using the wirespeed dial.
    it makes sense to me. The way it was written led me to believe it was an Amp selection on the Tap switch, which I could not understand how the WS would control Voltage. The WS controling Amps makes sense. I guess I was reading it literally and not thinking it through. I also noticed on the new litrature in the buyers guide for the 212 it now says seven tap voltage selection provides a range of 30 - 210 Amps.

    Thanks again for all the help.
