Reply:It should be in the manual.  IF you are using full power, its going to have to be big.  I need #6 for the invertec V350 pro.  I don't use all 425 amps, so I have a #8.DavidReal world weldin.  When I grow up I want to be a tig weldor.
Reply:I have a 100 foot number 4 for running my XMT304 or ProCut55 or AC 225. I also have a number 8 for the Weldpak 155 (max draw 30 amps and it seldom gets cranked past halfway). That 350 will need a huge cord if you plan on running it in the upper reaches.The difference between art and craft is the quality of the workmanship. I am an artist.
Reply:i got a 8/3 50ft from cyberweld for my mm251 when you figure no tax and no shipping they are cheaper than making your own25ft is $92.00 and 50ft is $183.00

Reply:the end are around $13.00 each so lets say $25.00 for boththat means you paid $75.00 for 50ft of so 8/3 cablethat $1.50 ft love to know were i can get a deal like that
Reply:I think #4 would be sufficient for your needs, maybe 6 if you're lucky.  As has been said already, your manual will most likely have something to say about the matter.It's nice to have the peace of mind with something overbuilt but you don't want to go nuts in the case of your extension cords, as laying down that #0 cable is not pleasant when you have to be working on something that requires you to frequently move the welder.

Reply:For a 230V extension cord you will need #6 AWG copper at a minimum, but #4 AWG would be better.  For the ends you're going to need something beefier than electric range cord ends.  If I had to take a guess on price for the wire you're looking at $2.00/foot or better.
Reply:According to the ratings in the manual he needs a cord rated for 50 amps continuous duty. Actually 48 amps at it's 100% duty cycle output and 50 amps at the 60% duty cycle output. So whatever guage that is, and the typical 6-50P&R's.
