What outlet is this??

[Bunbun]

I ask my builder to add an outlet for me to run a welder (that I haven’t purchased yet) and I see this outlet..? Haven’t seen one like this before. I do know it an 30amp circuit and I think it’s 220v. My question is, if the male plus doesn’t align with the wall receptacle can I just replace the wall out let to mate with the welders make plug.

Thoughts??

I think that is a 30 outlet but,,,,,, welders come with a 50,,,, 6-50-P. A 240V welder is specifically tailored to be able to be connected to a standard "welder" outlet.

I asked a builder for a welder receptacle a number of years ago but specified in the contract a 6-50. You can change the receptacle to a 6-50, buthe wiring may not support much of a machine. How large of a machine do you want to run? If you weren’t specific, you might be hosed on this since drywall is already up.

It is a standard 220V/240V for North America. Don't know if they are rated for 30A, though, The household 110V versions are only rated for 20A.

You can change the outlet, but if it is 10 gauge wire you're stuck with the 30A breaker.

Edit to add it could be a 6-30P, which is rated for 30A.

And 30A might be enough. 30A at 220V is 6600W, or 190A at 35V or 220A at 30V. Don't know how big your welder is.

looks like a nema 6-30. But Look at the writing on the outlet.

That depends on what its used for. If only used for a welder, you could swap it out for 6-50r depending on the duty cycle of the welder. you would need to change the breaker to 50a as well.

That really depends on the duty cycle of the welder as code allows reduced size wire for welder circuits dependent on duty cycle.

Depends on welder duty cycle...

Thanks all for the response. I am looking to run a millermatic 211 and from the website:
Input:16.6 A 50/60 hz single phase
Output: 150A at 215 VDC, 40% duty cycle.

Im hoping it’s just a simple outlet swap.

That machine will run from 30, change the outlet. 10 cable will run any machine that comes factory cord except 250 feeders and in reality it will run those with 035 solid and C25.
They are listed for 8/6 wire but unser special circumstances can output near 300a and at their rated can run 60%. I used a 10 cord on mine long time, never warmed it.
But,,, todays machines like 211 and the new stick machines dont even require a 50 breaker, 30 is fine. They dont come 50 plug cause they need it but because it allows them on a welder circuit.

Yup... just swap it out for a 6-50R.

Manual calls for a 30A circuit with minimum #14 wire. So you're good once you swap the receptacle.

So the wire behind the walls should be good?

So the wire behind the walls should be good?

You will only know that when you confirm what it is. Should be yes, but YOU need to confirm what wire and gauge it is and tell us so we can give you an answer based on verified facts and not SWAG's.

Electrician did a nice job of getting the screws to align properly.

I can't remember … is it vertical = 120volts and horizontal = 240 volts. Or do I have it backwards.

 

[sberry]

That recept is sposed to be 10,,, its not a welder recept and needed to be done correctly. 10/30. I would bet real good money on a WAG that the wire is just dandy and number 10. Its not a welder recept/circuit, no allowance for wire reduction. It will be a great circuit for welding.
That style of plug says,,,, its got a 30A wire and a 30 breaker.
In a dedicated hard wired circuit the breaker and the wire may be tailored, in a welder the wire may modified be but the breaker isn't to exceed the outlet rating. Motor over 3 needs hardwire, this prevents using a welder circuit for that.
You don't need to change the breaker to 50 unless the machine would need it.

Didn’t even notice that...ATTENTION to details!!!

New guys on the block here... not sure what all this means, but doesn’t sounds to promising.

It means the wire will be good for changing out recept for a 211.
It means the outlet pictured in this thread must have a wire minimum of number 10 and a maximum breaker of 30. Assuming it was a legal install the wire in it will be sufficient for conversion to a welder outlet.

Thank you sir!!
