I have a ac 225 volt arc welder can I plug it into the 220 dryer outlet?

Question

So the arc welder has what looks like an over sized regular 120v plug on it. The male plug of the welder doesn't match up with the female dryer outlet. if I make an extension cord with the proper conversion from the arc welder to the dryer outlet will it be fine? does the fact that the welder is 225v and the dryer only 220 change anything? Any help is appreciated, please don't make stuff up I don't want a new hair-do!

Answer 1

It will work as long as the circuit and breaker is sized right. The amps is what you have to worry about. Check the rating on the welder and check your breaker size. PS. dont mix up the ground and the hots or you might get a new hair-do.

Answer 2

Most dryers are set up with a 20 amp circuit. If the welder plug fits then it probably also requires a 20 amp outlet. No big deal if the breaker pops. Just reset it and plug the dryer back in.

Answer 3

Amperage! Your other 2 answers are correct, in my opinion.

Answer 4

That "oversized regular 120V. plug" you refer to

is probably a NEMA 6-50.

I doubt if your dryer is rated, or wired for 50A.

Answer 5

listen ,,,your house has a 240 line to the dryer.  the 225 volt welder and the 220 volt dryer are within the limits.

What you need to make sure is that the amperage on the circuit breaker is enough. The dryer breaker is probably 30 amps. The welder is rated at either 20 amps or 30 amps.

This you have to check yourself---I'm not there. then you have to change the outlet socket to fit the welder plug.

But do you really want to do your welding in the laundry??

Wouldnt it be better to make some sort of fireproof area in the garage?? or better yet a shed that is not attached to the house  ??

Answer 6

Something is not correct in this setup. If the exsisting plug looks like an oversize 120 outlet, read on the plug it's rating and voltage. The dryer outlet is a 220 volt/ 30 amp outlet, the welder may be a 50 amp plug, at 220/240 volt. If this is a 50 amp 240 plug, it will draw too much for the circuit breaker and trip off line continually. The solution is to install a separate dedicated circuit for the welder and put the outlet near where you will be welding.  The 225 volt rating is of no concern, since this is a nominal voltage as are the house 220/240.
