power cord

[travis]

i just got given a 35 ft long 50amp ext cord once used on a rv it is 6/3 with a 8 gage ground this will give me the movement i need in my work area

That's a pretty nice gift. Nice thick cord like that won't have very much voltage lost to it at all.

You have some very nice friends Travis. A cable like that is over a bill here if you buy new. 35' might just be long enough to reach anywhere in a small shop/garage. What kind of connectors does it have on it?

[travis]

one end has a male 4 plug other end is loose

[Tanh]

4 plugs? It might be a nema 14-50p. Does it look like this?



If it does you are in luck cus that's a dual voltage plug. You can run 240v and 120v with that cord. Great for having a grinder or saw handy where your welding.

That's exactly my plan for an eventual welding cart - provide 240V and 120V power on the cart itself (with a NEMA 6-50 receptacle for the welder and standard 20A receptacles for whatever else), with a hard mounted cord from the card that will plug into the wall. I'll probably end up buying an RV cord off Amazon and chopping off the receptacle end and just using the plug and maybe 25' of cord to reach anywhere in my garage or driveway.

male plug looks like that yes and i have a black red and white wire along with a green ground wire
ok so how do i run dual voltage ? i was thinking that today it would be nice to have a 110 and 220 all togather

How about just wiring in a power strip with a built in 20A breaker on it?

That's probably what I would do for myself.

Didn't see that you said that already on your earlier reply.

so theres no way to wire a 11o off the rv cord ?

There is, but to do it safely requires that you provide some lower amp protection for the 20A outlets. If you are at all unsure, get an electrician to wire it up for you.
