Default Can I convert 240v plug to 110v plug?

I'd just bought a Lincoln stick welder with 240v plug. But I don't have a 240v outlet in the house. So can I convert the plug to 110v and still be ok or not? And this will go to washer and dryer outlet, which is 110v.

Thanks guys.

as far as i know, you'll need to have an electrician come and run a new line from the fuse box.

Only if the machine says it is 240/120 compatible. It will probably need a 240v source.

go to home depot and get some heavy guage 220 wire and make an extension cord. make sure its heavy guage if not it will catch fire and probably burn your house down.

yes it is possible to turn a 240 outlet to 110. what is the welder rated at? and that will help us figure out what size wire you need to run.
your dryer outlet should be 240 already unless its gas which is rare.

What are you welding? What model and make is your welder? I made the mistake of buying a really cheap stick.

To answer your question, no 110v cannot be made into 220v.

if its a dedicated circuit a standard 3 prong 110 outlet can be made to 220v. its highly unlikely you have a dedicated circuit 110 though.

Most 110 is #14 gauge wire which is good for ~20 amps. Even the cheapest lincoln stick welder will need ~50 amps for max output and ~30 for moderate welding. So unless you have a hot and neutral that are #10, will only do moderate welding, and are 100% sure you are on a dedicated circuit, you will need to run a line from the breaker box. (3) #6s and a 50 amp breaker should do it. Needs to be wall disconnectable (plug) or you will need a switched disconnect. Easiest way to do this is just get SO cord comprised of (3) #6s and a dryer plug male/female setup from Home Depot.

essentially a 3 wire 110 outlet has a "hot" (usually black wire) 120V, a neutral (white) and a ground (green or bare copper). a 220V outlet has 2 "hots" and a ground.
basically move the "white" wire (old neutral) to another breaker and make sure its the opposite phase and you have your 220V outlet. but thats if its a dedicated 120V outlet. if not your going to convert all the plugs on that branch circuit to 220V. i wouldnt recommend that if you dont know what your doing.
you would need a 2 pole breaker or 2 consecutive breakers "on top" of one another. they need to be the same ampacity rating too. the handles should have small holes in them and at that point should be "tied" together using a piece of solid copper or equivalent.

The dryer is gas, and it's 110v. And I have this

http://www.lowes.com/pd_98103-1703-K...der&facetInfo=

And now I am trying to figure out how to make it work. I will be just welding exhaust pipes and some thin metals for now. I think the best way is to run a new line from the circuit board.

This is what I am going to do.

do you have access to your breaker box? all you need is a 220 breaker and wire and run it your self. its not hard. its better than burning up wire in your house. if it runs too hot it will catch fire. 220 is just two 110 hots and a ground. maybe its the electrian side of me, but i'd hate to hear about somebody burning up there house because they did something stupid. thats all.

Electrical is not something to mess around with if you have 0 clue what you're doing honestly.

I've some experience with wiring so I am not worry about it. It is just that I wanted to find an easiest route. I guess not. Alright, thanks guys.

14awg is only rated at 15 amps ... 12awg is rated at 20 amps and 10awg is rated at 30 amps. fyi

All houses are single phase, moving the neutral to another breaker will be the same phase no matter where it's at on the panel. But if u make a 240V plug in (2 separate 120V lines) then they must be on a double pole breaker

What do you think a double pole breaker is? Its just two breakers tied together that are grabbing the 2 different HOTS coming in from the power company.

The above way is not the way I'd do it, but it would work just the same.

you dont know electricity. leave this thread.

second under the assumption that your breakers are working properly you wont burn down your house. the breaker is there to protect the wire NOT YOU or YOUR HOUSE. overloading a wire will make it hot thus possibly causing it to smolder and burn. however your breaker is there to prevent this. a little common sense goes a long way.

when i wired my outlet for my welder i just ran some #6 which is good for 60amps.

the easiest thing to do would be grab the proper sized wire, a 2 pole breaker and add a remodel box right below the panel because you can drop that wire 6" to your new box and wire it up to the outlet your done.

Actually, he is partially right. Houses are all single phase utilizing two separate line wires, neutral, and ground. It works that way because you are only drawing from one phase on the primary side of the transformer and two coils on the secondary creating your typical residential wiring configuration. So line-line would be 220v, line-neutral would be 110v. It is important to realize that it is not separate phases.

The ideal way, as stated above, get some 6awg copper wire, a 2-pole breaker and a 50amp 250v receptacle. Although you could use a 8awg copper if conditions are met, but I wont get into that. Nothing wrong with wire being a little oversized.

I am a licensed electrician.

I would also like to add if you only have a 60 to 100 amp service in your home try not to be running other large amp draw items while using the welder. With a 200 amp service you shouldn't have an issue

If you knew half as much about electricity as I do it would make your little head pop so check your sources before you open your digital mouth.
