    Question Initial settings for 30A Spoolgun

    Just got a Miller 30A spoolgun attached to my Millermatic 250. I will be practicing on 1/8 Al coupons using .035 wire, Argon at 20cfm. As the control module I bought doesn't have any knobs it looks like the 250 will control wire speed and voltage. Does anyone have any suggestions for initial settings or general tips for learning to use the spoolgun for Al??

    Isn't there a red knob on the bottom of the handle? That adjusts wire feed.
    Also I prefer bigger .064 wire myself. It has a lot less wire feed associated problems.

    I would get some 1/4" material to start out with. If you are just starting out with a spoolgun on aluminum, 1/8" stock may be a little difficult until you get a feel for it. I just recently went through this same process.

    Wire size shouldn't be a problem with a spoolgun

    Dr. Gas, regarding a connection for your spoolgun....did you install or was there already installed on your welder the optional receptacles module for connection of a spool gun? For info check the owner's manual for your welder or if you don't have one, download one from this site by inputting your model and serial number at http://www.millerwelds.com/service/ownersmanuals.php

    No hijack intended here. Can anyone translate the WFS ipm settings copied above by tenfingers into the 0-10 control settings on the handle of the 30A? The best I've heard on this so far is to adjust the 30A on-the-fly. Is there an equivalency chart somewhere for those of us connecting the 30A to a power source with no ipm readout?

    measure how much wire comes out in 6 seconds and multiply it by 10= IPM
    or 12 secs and X 5

    The owner's manual states 70 To 875 ipm wire feed speed. At a zero setting you should be getting 70 ipm and at a 10 setting, 875 ipm. I would expect it to be a linear progression in between. If that's true, at a 5 setting, you should be getting 502.5 ipm. You can verify that by using the technique gordfraser posted.

    I dont see the need to know that, Set the voltage or temputure and then fine tune wire speed as your welding.
    Doing it this way will by far give you better results that a pre determined setting by the factory.
    In put voltage from the utility and what machine your using will vary.
    Using settings that the factory recommends will however get you close.
