Welder cart outlet questions

[DeadSock]

The outlet will be directly below the panel (perhaps a foot or 2) and would like to size it for 50a. The wall is exposed for now, but will get finished with drywall.

My wish is to have a cart that the welder plugs (or is direct wired) into along with a 120 outlet. The cart will have a short whip and will normally be parked within 10' of the 50a outlet. I'd also like to make an extension at some point.

My thought was to put in a 14-50 outlet and a 5-10' whip to the cart which would provide 240 for the welder and a 120 for an outlet or 2 (GFCI of course).

What's the proper (and/or cheapest) manner to protect the 120 outlet(s)?
Build in a small breaker box (baby box)?
Perhaps a marine push-button breaker on the cart for a 120 outlet?

Or should I simply have a 6-50 outlet with a 5-20 nearby (with independent breakers) and make a 5 wire whip that has both a 6-50 and one 5-20/5-15 plug?

I sort of like the idea of the finished outlet being 14-50 in some rare case someone wishes to plug in an RV.
Then again since the primary purpase is for a welder and a 6-50 seems more appropriate.
The cart having both 240 and 120 is mostly for convience of not needing multiple extensions run if I'm working outside.

I did the very same thing - I went the small breaker panel route.

One of these and a handy box

Hmm...

I like the 14-50R.

I was thinking distribution blocks or DIN rail, but you just need something like this... but obviously smaller...


I think the 4 circuit small box might be your best bet.

Got a link?
That looks just about perfect

Forget all that, its just clutter. Put a 120 in a common place. Use the common wires and you can use a common cord for extension. This is a good case of way too much thought, the 120 need separate overcurrent and do you need 2 circuits on a little welding cart.

Its a good learning curve though and you get to see how many code issues can be in one situation. As for the outlet its so short there is no reason not to use an 8 or 6 since its covered,,, while I was at it would add another in trade for all the extra junk on the cart or put a panel below the panel so its easy to get at.

Available at Amazon.com: This one has the separate ground pin, too.

Uses a fuse and from the shape of cover, I'll bet it's a screw-in type. Can't find any details.
