I work with conveyors and sorting equipment that uses these plugs. They're always 220v 3 phase in my case, but they're actually rated 480v 50amp. Here's the end yours would plug into.

I’m on my phone but that looks like only 3 prong. Single phase if so. As ronsii mentioned it is just a twist lock type connector.

AAAND I stand corrected. I gotta learn to be more observant...

Here is a pic of the 3 phase plug on my plasma cutter.







...what a dumb ***.

PLUGS don't matter.

No decent welder sells with a plug

The user puts it on and it could be anything.

That plus has three prongs, that's 220 single phase
Two hots and a ground.

Three phase has 4 connections, three hots and a ground.


Read the manual.

As mentioned, some machines can be run on both three and single phase with some configurations on the inside.

I've seen welders like that go for a few hundred at auction because the homeowner harry bid up the small machines and left the good ones alone.


Just buy one if it's cheap enough.
The first one will not the the cheapest one.


If you get one of those for five hundred or less, you could even use it as trade in at a dealer for a new machine.

The plug on those machines is 3 phase the metal case is the ground. Doesn't mean they are using all 3 legs. Could still be wired for single phase.

Yes, the better photos show that.

However i say again.
Read the manual

Many machines can be reconfigured with bus bar jumpers inside and use either or single or three

So many plugs, many look alike.









Nema, Shrouded, Non-Nema , Twist-lock. straight blade, marine, Industrial.....etc, etc.
I have bins full of connectors , probably over a hundred. When I go to wire up a new machine , I rarely have the right connector. I even stump the local electrical supply half the time. Now we're using some of the shrouded twist locks with integral safety disconnects. Cant remove the plug without power shut off. Unless you have the information plate on the machine, or the manual, its an expensive guess. Even then, many times the manual isn't correct one, or covers several different machines.

Hopefully he can find a machine that will work for him. I think a 350MP is a little over the top for 1/4" steel.

Did you look at the nameplate on the machine? Plugs come in all shapes and sizes. I too have a box of all the wrong plugs. NEMA and NON-NEMA drive me nuts, at a glance they look the same but are often reversed. Only one dude at Platt can order the correct non-nema plugs and sockets for my shop, the rest are deer in the headlights. Last year I had maintenance replace a faulty socket and now I have one odd-ball NEMA outlet in the mix. Mad everytime I try to use it.
