Also, Your gunna need somethin a little beefier than awg 10 for a 100ft run. It MAY work, but ID probably lean more towards #8 becaue of the length. then again, Im not an electrician.
I also wonder.... what size wire is used, and how far is the AC outlet from the main panel?
Otherwise the 100' #10 cord and the plug ends you've chosen are fine with a 19.5A load.
BTW: plugs & receptacles are usually rated for 125V or 250V even though the nominal voltage is 120/240V, and the equipment itself is rated for 110, 115, 208, 220, or 230V to account for voltage drop.
Yeah, if my voltage drop calculations are right. Asuming that the outlet is wired with 10 AWG copper at roughly 10 feet of cable length between the breaker and the outlet, you would have a voltage drop of .5 volts at 240 V/20A. Over a total length of 110 feet (wall plus extension cord), you will have about a voltage drop of 5 volts so 10AWG copper will work just fine and will still be sufficiant to run the welder.
sounds good ...i'll start the hunt for a 6-50R and a 6-20p.. might just go with a box at the receptical end.
...i'm confident now nothin' will :nuke:
