Hello there and welcome to Just Answer. My name is XXXXX XXXXX I will be assisting you today. I am an engineer with over 30 years of electrical and electronic training, repair and installation experience. I will try and answer your question accurately and precisely so that we can get you on your way.

I need some additional information from you in order to fully understand the situation.

The welder will have a plug on the end of the cord. Look carefully on the plug and you will see a configuration number like 5-30 or 6-50.

Can you tell me what that is please?

Please let me know so that we can continue.

This is an old stick welder. You won't find any numbers on plug.

Ok, then take a look at >>>this chart<<< and tell me which plug configuration you have please.

If you don't see yours listed, you may have a locking plug in which case it will be >>>shown here<<<

Let me know which plug you have.

Please let me know so that we can continue.

50 amp 125/250 volt

Do you have three pins or 4 on the plug?
Customer: replied 3 years ago.


Ok. Your receptacle will have three connections. The two hots will connect to the X and Y terminals and your ground to the remaining one.

It does not matter which hot is connected to X or Y.

Please make sure you ground the receptacle and the box.

I'll be here if you need further help with this issue. Please let me know.

Thanks but had it hooked up already. had to be connected to breaker in box also as I stated in my question. It is done though

I'm sorry - maybe I was confused then.You indicated that th breaker was in and that you had a receptacle and needed a wiring diagram - which is why I asked you several questions about the plug.

Wiring the breaker is easy. One wire to each pole so I assumed you had that part.

I hope it is a 50A and that you have the correct wiring size.

I'll be here if you need anything else.
