Hello all,

I plan on ordering the Lincoln Electric Power Mig 215 MPi Multi Process Welder. I have a roughed in 240V 4 11/16" box with 4 wires. I need to install the matching receptacle for this welder but cannot find any information on the plug type (even the instructions don't mention it).

Does anyone know what receptacle this welder needs? From what I've been able to find it may have a Nema 6-50P plug but I'm not 100 certain. Ideally, I'd like to have the outlet wired before the the welder arrives.

Thanks.

welders typically use 3 wire ( no neutral) as they are 240 volt only . the only time 4 wire is used is if you need a neutral to supply 120/240 to the outlet
typically they use 6-30 or 6-50 depending on the amperage of the welder

Why did you run a 4 wire feed?

I didn't run the 4 wire feed. It was a new construction home and I requested 240V rough-ins for the garage in anticipation of a Lift and my welder so for some reason the electrician ran 4 wires. When I installed my lift (https://www.garagejournal.com/forum...ad-lets-see-them.347432/page-12#post-10132451) I capped off one of the wires and ran the 240V with a ground and 2 hot legs.

Now I'm looking to do the same for the other rough-in but for a welder this time. I do know they use only 3 wires but need to know what receptacle I need to install.

Wow, overkill by a lot, but it wont hurt anything except the trouble of terminating the wires and closing up the box.

I bet a call to lincoln tech support gets you an answer, but if it was my shop, I'd do a 6-50 and then change the welder plug if needed. It's the most common plug type for welders and plasma cutters.

This.

My 210 is a 6-50, this would be as well.

Though since it is dual voltage, any old 120v outlet will work!

Appreciate the info. Also got a couple of 20A 120V Outets that the manual calls for.

Since I have the the 240V available I might as well wire for that too. At that power rating it'll let me weld a thickness of steel I'll never need or use lol.

It's a 50A circuit for which #6 wire is recommended.

Not for a welder.

I didn't look up the duty cycle but I bet #12 is sufficient. The NEC allows for downsizing wiring based on that and still using a 50a breaker and receptacle

Edit...you are in the great white north though. No idea on CEC rules for that

I simply told them I wanted a 240V 50A (The Lift circuit is 10-2 30A) circuit so that's the cable the electrician ran since I'm pretty certain the sales centre didn't exactly specificy to him that it was for a welder. Not complaining, since I got what I paid extra for lol.

It's all good. I said it will work fine.

And if it wasn't specifically for a welder, derating wouldn't be allowed, so yes, you got what you asked for.

It's just an exception that isn't commonly known.

Lincoln finally got back to me. They confirm it is a 6-50P Plug. Thanks all for the feedback.

Going to have fun trying to find a 4 11/16" box cover plate with that size cutout in the middle lol.

A 2-1/8" deep 4" square box would have worked just as good as a 4-11/16, but since it appears it might be too late...

Unfortunately the 4 11/16" boxes were builder installed so not my choice. But I do appreciate the extra space for thicker gauge wire.

I'm in Canada so ordering something that small from the US would not make alot of sense. I'll check with my local electrical supply shop. Amazon Canada may have something as well since I managed to find what I needed on there to wire my 2 post lift to the same size of box.

Didn't catch the Canada part. If the supply house carries Raco, the part # is 888. You could also use a two gang mud ring and a plate.

Or if it's surface mounted, which a raised cover is intended for, just change the box.

I managed to find a 4 11/16" 1/4" raised 2 gang mud ring at Home Depot. For some reason 2 of the 4 holes do not correspond with the holes on the box. Just going to drill new ones.

That's the way they are. Blanks, raised covers, and mud rings mount with two screws.

The Blank Cover Plate and the 1 gang Mud Ring I have both have 4 holes that line up with the box.
Click to expand...

The box comes with two screws. There are four holes in case the ring or cover needs to be rotated 90°. You can drill holes if you want, but the intention is for two screws to hold the ring

I don't have a ring or cover, only a blank. A ring or cover will have two more holes just in case the box is mounted facing the wrong direction.

They almost certainly assumed you were planning for an electric car, or a sub panel for 220V shop tools.
