220 volt to 110 volt ?

I have searched and have probably seen the answer but didn't realize it because of my NO knowledge of electrical wiring
I have read the posts where TT have been hooked up to 220 by mistake and I really don't want this to happen....
I have a 220 volt plug for my arc welder and I was wondering if it is possible to make a splitter of some kind to plug into this so I could plug my TT which is 110 v 30 amp? [with no melt down] I would not be attempting this on my own but rather a certified electrician would be doing the work.
Is there an already made adapter available ?

You can run down to Wally World (Wal-Mart in Canada), in their RV section usually near automotive, and buy an adapter already made for this purpose if your welder has the same kind of 50 amp plug as below. They are less than $10. Most all of your RV dealers will have them also, but may be higher.



or



Either one of these adapters works by just terminating one of the 110 hot lines coming from your 220 volt outlet....so you have just one 110 volt hot line to power your camper, as it should be.

Personally, I prefer the dog-bone kind in the top pic (it looks like a dogbone when laid out), but either one does the same job.

IMO, I think you might have a problem doing that.
There is no Neutral wire in your welder's socket; just 2 hots and a ground wire.

Typically, the ground wire is not of sufficient gauge to handle the job of a neutral. So you ONLY have 220VAC with no possibility of "downshifting" to 110VAC.

OK, you might want to read this:

welding

It explains how you can change the breaker and receptacle to make it work (no adapter), but you then wouldn't be able to use it for welding.

EDIT: I see Lou was busy as I was typing and said the same.

Ok I will still need my welder plug in so how about my dryer plug in which looks like this, possible to get or make an adapter?
You can see I am grasping here to get it done easy as i like all things plug and play....

This I think is 220v and 30 amps ? 110v for dryer motor and 220v for heating element..

Just buy a rv receptacle that will work right and be done with it.
There 20 bucks at Lowe's or home depot.
Get a 30 amp 110v breaker and 5' of 8 gauge wire.

Put in the proper RV-style 240-volt receptacle in place of your current welder plug. It's a NEMA 14-50R. Accept no substitutes.

MAKE SURE you tell the electrician you want all four wires in place, even if you have to pull new wires into the box from the panel! Tell him or her that it HAS to be a full, correct, 50-amp service. That includes a ganged 50-amp double breaker

L1, L2, neutral, and ground. ALL FOUR!!!

Then, buy the RV adapter from post #2 above to get your 30-amp RV service.

Then, replace your welder's plug to match the receptacle.

Wha-laaaa!

Since I haven't used my welder in a long time, that last part I have yet to accomplish, but someday, when I get a Round Tuit.......

Here is a great little pdf file that hopefully can be made a sticky somewhere by the administrators. It is a handout to electricians, and everyone else on how to correctly wire for a 30 amp rv outlet. We have had several members as of late who have had family and professionals incorrectly wire for their trailers, with ensuing damage.

I wish all RV dealers would include this every time they sell a trailer with 30 amp service.
