    I paid $130 for a 50' 8/3 soow cord with 6-50 ends a couple years ago. I can still find them on fleabay and such for similar prices. I know it has the wrong plug, but a short adapter to your drier plug would give you flexibility for when you have a real shop with good power (sounds like that is what you want in the future?). you would have to run 2 cords together to get the 100' you need but that is $260 for 100' of length and then likely another $40 or so to build a 4-6' adapter cord.

    I was working at a new place last year and the shop was wired up with 14-50r everywhere so i just made a small adapter. Pretty easy to do and now I can my equipment off 6-50r or 14-50r receptacles. Just one more thing to have or do. I'm happy I went with 8/3 because later on down the road i picked up a mm251 and I needed the heavy gauge wire to run it. It wasn't in my original plan but it came in handy. Food for thought..

    Just got a response back from miller tech. They said 30a is maximum and 10/3 is minimum recommended for 100'.
    Im still with you guys on the 8/3 though except for price...

    up here in the great white north,
    $110 for 100' of 10/3 SOOW
    $350 for 100' of 8/3 SO

    cannot find 8/3 SJOW locally for the life of me

    I second Broc's 8/3. You shouldn't have to worry about any voltage drop if your under 250ft.

    Thanks broccoli. Now I just have to track down some 8/3...

    The 79' includes the original wiring in the wall and using Minimum wire size of 12 which is allowed for machines that have a duty cycle. There's a formula to figger it out.
    But your dryer receptacle by code will be wired with 10g so you are starting with a bigger wire than what is listed in the Miller manual.

    So whatever that length is from the panel to the dryer receptacle

    And then you want to run out 100' feet from there.

    8/3 cord will certainly do

    Look for sjo- junior - good for up to 300v- might be a little cheaper

    SO- is good up to 600v

    The W- for wet applications

    Haha I've seen the prices and that's why I don't wanna f this up.

    as far as I can tell from the 200dx manual:
    Single phase 60% duty cycle
    230v input
    20a input at rated output


    further in this chart it lists max conductor length (EXCLUDING FLEXIBLE CORD OR CABLE) as 79' of 12awg


    So I should be able to run off my 30a dryer breaker/line right?
    And I assume to make up for the extra 20' or so and to make up for the "flexible cord" bs if I bump up to 8/3 I should be ok. Maybe I should put in a 30a line fuse in on the welder side to protect me from the 8/3 catching fire? Any one know if I'm assuming correctly?

    Stu-
    There isn't a code for extension cords. There are guidelines and on a job site you can have OSHA rules to follow but at a home nuttin'.

    Anyhoo-
    I would buy a 10/3 100' cord from lowes Home Depot and then change out the ends.

    I don't think you want to see the price on 100' of soow cord.

    What is the maximum draw on that machine? 8/3 would be your minimum but 6/3 would be safe and would allow you use it for other things down the road. The cost difference would be minimal up front verses replacing it down the road with a larger gauge wire should the need arise.

    thats kind of what i figured. call a sparky.
    chances of running the machine at max duty at output are slim but its nice to have the ability.

    i have a 50A stove plug but its probably another 50' away bringing the total to 150'.

    i hate so much living in a rental house. who builds a shop without 220v service to it? some people...

    thanks for the input stu

    ext cord.

    Nearly forgot, The stuff i described above was using the full 50 amp rated plugin setup , with the 30 amp you describe there could be an issue. Best Consult an electrician. You might be tripping breakers life a mofo if your pulling rated max duty cycle for the machine.

    I think you could get away with the 8/3

    Im a welder , not an electrician. I have used the lws supplied 50 foot and 25 foot 230v extension cords, they are 8/3 wire. I used two 50 footers once on a job and didnt have any issues. I guess if your running max output on the machine at that distance there could be the potential for trouble. I guess it depends on current draw and for how long you are doing it. one continuous piece of 8/3 probably would be better as there is no possibilty of the plug and connectors having a poor connection that could cause trouble. If you had to you could probly use heavier cord. Probly be best to consult an electrician and the appropriate code book.
