I'm looking to get a welder for my garage. I found that there is a 220 already wired up but the plug is different from a dryer 220 plug. It looks like:

I tested it with a voltmeter and it does show it is a 220 socket with about 55-60amps. Is there a converter of some sort that I can get to make it look like my dryer plug? Also do they make extensions for this kinda plug? The plug is several feet from the table I want to weld on. Thanks guys.

 

Mine exactly like what you have, well it was. All I did was go down to the industrial electricians warehouse. They make custom length extension cords, and all I did was get the appropriate end for each connection.

The guys down there know so much, just draw what you have and what you need... my 45ft cord cost me $35.

Wow great stuff! I was hoping the cord wouldn't cost more than 100 bucks. Thanks!

 

Keep in mind that the different shaped plugs are for different amperages and phases.
Be sure the receptacle that you are plugging in to is rated high enough for your welder.
Ask plenty of questions when you go to get one made, maybe even bring some pics........

 

Uhhh, I really hope that you didn't measure the amperage unloaded.

 

I don't get your post, please explain in more detail. Also I'm looking around for these industrial electrician places, if anyone knows of one in the NYC, Northern NJ area, please let me know.

 

So long as you're rated at 220V and you can supply enough current wire/socket/breaker wise it doesn't really matter, especially if you're just making an extension cord. Find the terminal you need to go into the wall socket, run your extension, and put a receptacle on the other end which matches your welder.

I just wired up my friend's garage for 220 and made an extension cord since it's easier than running conduit. That 4 pole (I would have gone with 3 pole if the Home Depot had it) 4AWG does get expensive and weighs a ton, for ~45ft it was $150 and with a little discount. From what you said I don't think you'll be needing that much but yeah... If you end up changing the sockets, terminals, and you're driving a fairly big welder use oven receptacles and terminals. Dryer ones are rated a little lower current wise. Also, just curious too but how'd you measure the current you were pulling?

 

A household voltmeter. It works pretty good. Picked it up from home depot. I just need like maybe 10-15 feet extension. Better make it 20 just in case.

 

I'm not trying to get in an arguement with you here because it's really not a big deal but I don't know how you measured any current without any appliance inline and with a standard voltmeter. Oh well, good luck with the "extension cord".
