    Default please help what to buy

    I am helping out a friends shop weld good size aluminum boxes and am welding with my dynasty 350 right now but it's way way way to slow and owner said they were wire welding them with spool gun or push pull set up Most the plate aluminum is 3/8 to 7/16 and they have been tacking on 1 in blocks to all four corners on these parts So my question is what set up would work for me ? I don't wanna spend the farm but would like to get a wire set up for this any advise would be great thanks in advance

    Also I might be able to get a power source as well if that would help out

    Sounds like a perfect job for a Millermatic 350P with the Alumapro Push-Pull gun..

    I have one and it is the cat's meow for MIG.. between the MM350P for MIG and the Dynasty 350DX on TIG... you can pretty much handle whatever comes along....

    Just my 2 cents worth.. But I own both.. and you could not trade me out of either one...

    For my money.. nothing comes close...

    you might find it more cost effective in the long run to buy the more capable machine from the beginning and be able to handle the larger stuff at longer duty cycle... rather than being limited by a smaller machine..with a lesser duty cycle.
    Doing those aluminum boxes continuiously at decent speed and not needing to stop and let the machine cool between beads..will require some horsepower..

    Amperage is a function of Voltage X Wire Speed for a given size wire..
    See figure 6.9 page 32.
    Not so much Amps available... but the duty cycle at the given amperage..
    See figure 4.2 page 11
    this is the amount of time that you can weld at that output before you have to stop and let the welder cool

    The 30A spoolgun is a well made piece of equipment and heavy duty... but it is tiring to sling all that weight around all day and the frequent spool changes...

    Great for smaller jobs..

    one feature that the MM350P has that most others do not.. is the ability to pulse... this gives a pretty bead that looks a lot like TIG and reduces the total heat input to the work..

    Will I don't do very much of this and prob won't after this but this might go on for a few months but just can't drop 5 g on a unit to weld these things worst comes to worst I will have to keep tigin it but its taking to long I was thinking a millermattic 200 with a spool gun but not sure if that would work or not
