    Default 12/3 so p 123-72-msha

    Got about 200' of this for 20 bucks. A friend had it in his shop and never used it due to the weight and length.

    Running from an engine drive to a 211, how long would I be able to make an extension cord? I have seen post about this but not finding out enough.

    Here in the manual for the 211, page 22

     When calculating max. cord length, remember to include conductor length from line disconnect device to input power receptacle.
    Input Voltage
    Input Power
    Phase Hertz Conductor Size Max. Cord Length
    120 V 1 60 14 AWG 27 ft (8 m)
    230 V 1 60 14 AWG 53 ft (16 m)

    And that's 14 gage that you can run 230v twice as far as a 120v?

    Anyway, What would be the max length with 12/3 SO from the engine drive 230V receptacle? if possible?

    I have made a few extension cords but always thought 12/3 was too small so I figured I would ask if this can be used with 230 for the 211.

    You could run it out 100'

    You'll get some voltage drop but the 211mvp can handle the drop in voltage-and due to the duty cycle of the machine you won't burn up the cord.


    You'll need to adjust settings as it may not weld the same as what the door chart reads but we adjust anyway.

    You also have consider that the 14g in the manual is for RATED output 150amps.

    The only problemo with 12g is that it doesn't fit very well in 6-50 connectors- just so small.

    But it was free

    This cord is huge compared to 12/3 from Lowes. I mounted them to install on e track, easy to move into the trailer. But the SO is a bit heavy for that even and probably wont get moved around much unless I can cut it down and use it to run the 211.

    100' is more than I thought. I might give it a go.
    Thanks

    Don't use it coiled up like that- run it out or loop it in figure 8's on the ground.

    We keep ours at 50' lengths- 100 is just a PIA

    It can get very hot if it's coiled up and you have a heavy load. I've seen pics of cords on reels that melted and caught fire.

    Copy that! That would be cool to see, but not in my shop... I know I have gotten things pretty warm when really cranking. I wouldn't want to start a fire. Thanks!

    Here is a thread about a reel that melted and burned - an electric heater was the load.
