Can I use a 10/3 110v extension cord for 220V? - Pirate4x4.Com : 4x4 and Off-Road Forum

Blackdog76 · 02-01-2010, 10:14 AM

I just upgraded my Lincoln SP100 to an SP 170T and need to again run an extension cord from my house to the street. The cord I have been using is a 10 gauge 3 prong cord. If I lop off the ends can I rewire it to work with 220 plugs?

Yes, should be good for 30A.

Found this on welding web. Over 100 posts on this so it looks like it's working for this guy with his Tig. My welders specs are
230V/60Hz 20 Amps @ Rated Output
208V/60Hz 22 Amps @ Rated Output
so it should be OK.

Yes, the size of conductor sets the amps it can carry. The thickness of the insulation determines the volts it can safely handle. The max volts is usually stamped on the side of the cord in tiny writing.

i use 12/3 for my 20a plasma. its the same size that the factory cord is made from.

Also, the length affects the current capacity.

I think it's around 1% for a 50 foot 10/3. Not too worried about it. Used the plasma today with the modified cord and it worked great.

Yes, I used a 10-3 50' "YellowJacket" Heavy duty extension cord from Lowes and added the appropriate ends to match my 220V outlet and my welder. It was cheaper to buy the extension cord and cut off the ends than buy the cable by the foot off the roll. It works great.

Sort of, it affects the voltage drop. Longer the cord, the lower the voltage available at a given amps. Motors and welders don't like low voltage, good way to burn them up.

i've been running my pro mig 175 for a couple of years now on a 10/3 cord.the cord is 50 foot wired into the panel on a double pole 30 and has a dryer plug on the business end.i've never popped the breaker,even while turned all the way up burning 1/4 material for long periods of time.
