Welding outlet the same as a electric stove?

Ok so I had an electric stove put in my shop years ago to heat stuff up (till brown and crispy LOL) is the 220 outlet receptical the same as what is needed for a 220 welder plug in, or will I have to change the outlet.
 
The outlet will be determined by the welder you buy as there are different ones. That said, there are various types of 220V outlets and the kind you get will be determined by amp draw of the welder itself. By that I mean an outlet for a machine with a 30 amp draw will be different than the outlet for a machine with a 50 amp draw, and even then there are typically at least two designs for each amp rating. That being the case, Lincoln may choose to use one design and Miller another, even for machines with identical amp draws. Either way you go the only way to answer your question, and be 100% sure of the answer, will be to have the welder in your possession and match it up to see if it's the same as what you've got right now.
 
Stove should be a four prong unless it's one of those old shared ground & neutral abominations.
Welder should be a three prong.
The electrical code book should have images of the various Plug and receptacle versions.
 
Fred, some are the same some are not. You can go it either way and change the plug or the outlet to match. I did that with my welder that I just got and just made sure both welders use the same type plug and they are both the old type as in 3 wire set ups. They say the 4 wire ones are better and that is code now but the 3 wires where used for many decades so you will just have to look and compare them to know what you have and what will work
 
The answer (sittin here not knowing for sure what your welder requires and NOT willing to take a guess) depends on what outlet/receptacle and what voltage(s) and amperage the welder requires.

Many typical AC buzz box 225 amp welders are straight 240 volt (i.e. NO 120) and require a 50 amp 2 pole 3 wire grounding outlet. That outlet has 2 Hots (L1 & L2) plus an Equipment GroundING Conductor, but no true Neutral.

Some older stoves were 240 volt 50 amp but had some 120 also (maybe a light or convenience 120 volt outlet) and in days long past used a 240 volt 2 pole 3 wire grounding outlet BUT USED THE EQUIPMENT GROUND AS A NEUTRAL!!!!!!! A CURRENT NO NO

Some newer stoves use 240 for the burners but have some 120 volt loads and are now required to be served by a 4 prong outlet with 2 hots (L1 & L2),,,,,,,1 Neutral (for the 120),,,,,,,1 Equipment GroundING Conductor

SOOOOOOOOOOOOO if the outlet you currently have is the same configuration as the welders plug (i.e. plug fits into your receptacle),,,,,,,,And has a sufficient current rating (perhaps 50 amps??) and is rated for your welders voltage (240) SURE IT WILL WORK

It may also be possible to change the welders plug subject to certain specs but Im not gonna open that can of worms unless you need it

BUT IF NOT (less then sufficient current rating or not enough poles or not enough voltage rating) THEN NO IT WILL NOT WORK

Any range plugs I've seen are 4 prong, 50 amp. That's all I use on my welder... which is a 225 amp job. Just change the plug on the welder cord to add a range cord whip and use the appropriate wires in the range cord. Most times that's going to be L1, L2 and the equipment ground.

Welder will normally require 3 prong- two hots and a grounding. If your receptacle is 4 prong, get a 4 prong plug, and just don't use the neutral prong. As long as you don't tell B & D where you live (so he can't come out and personally pummel you about the head and neck area for flaunting the code), it'll work.

Q. When is a 4 prong plug just like a 3 prong?

A. When nothing is connected to the 4th prong.

But heed John T's discussion on ampacity (remember the row we had over that word a few years ago?).
 
The old 3 prong crow foot worked fine.I consider the later range cord junk.Dont change the welder plug.Make an adapter with the new junk range cord and a crow foot outlet.Look at the new and old plug and tell me which one will handle more current.
 
Either one will handle it fine... seriously. If you only knew what's been run through a range cord around here...

Crackerbox welders want a 50 amp service. Range cables provide it assuming the wires that feed are sufficient... It seems a lot less trouble to me to put a range cable end on the welder and use the outlet he's got (and maintain that outlet for other uses) than it is to change the fixture.

I had the crowfoot range cord on hand so just buying the later outlet made an easy adapter.Friend gave me 3 of those later outlets right after I bought one.My planer and 2 welders plus extenstion cord are all crow foot.
 
As an electrical engineer I like the word "ampacity" and when I practiced lighting engineering I liked the word "efficacy". Of course as in any other trade we spoke our own language but all the engineeres and techs and contractors understood it. Its why I still refer to Neutral as a GrounDED Conductor and the Equipment Ground as a GroundING Conductor and what lay persons call Ground Rods as "Made Grounding Electrodes"

Have a good day Counsellor

No I found out they are not the same. Also the stove only has a 30 amp breaker and the welder calls for a 50 amp. So I will probably drop one down from the breaker box.
 
Here are some pictures in case someone else wants to know what I have been pondering.Shop has the crows foot set up, garage miles away has short and long prong welder outlet and 50 amp breaker set up.

I buy crowfoot range cords for 4 bucks at a salvage store.Reminds me Ive got to make up another adapter cord ,I had borrowed his Airco Dipstick 170 welder. Nice machine that could Mig,stick weld ac or dc.It could not use Flux core wire.I gave him the adapter cord because the garage he was going to use it in had a crow foot outlet.The Airco had the later wimpy looking range plug on it.
 
My Lincoln 225 welder I bought in 1964 has a range crow foot cord on it.#8 wire.The new models have a #12 wire cord.The cables are one wire size smaller.Sounds like Lincoln got a case of the cheaps.I know welders have exemption but pulling 50 amps on #12 wire is far out.The older electric stoves switched voltage to get different heats.The new variable controls will burn your soup on low setting.When a burner element opens and arcs it makes the women wild.I had an oven element arc in a glass door stove.Wife ran outside.240 volts make a bright arc.A top burner arcing has made many women switch to a gas range.
 
I have 3 of those plugs on the shop shelf.They can be used on a range or dryer by using a different ground prong.
 
The cost of copper is gettin HIGHHHHHHH maybe some are takin short cuts??? but it would be troublesome if they exceeded a wires ampacity. I dount if their legal staff would approve of such lol
