Default AC input power connectors

I'm beginning to think I may need to take up welding and have been looking
at the MIG machines at Horrible Fright . ( I know I know ) The thing that
bothers me is the silly plugs on all their machines don't look like ANY of the
common "dryer" receptacles. They have one small and one large flat blade
and the round ground pins. The receptacles have an L shaped Neutral and the
blade sockets are both wide or the other have the blades at an angle with
the L shaped neutral. (and that has no Ground.)
So what is supposed to be used? Any one here that will admit to having
something from that schleeze outfit? :-)
Thanks
...Lew...

A typical 230V welding machine uses a NEMA 6-50 configuration, as all it needs are two hots and a ground.

A modern dryer is a 4-pin NEMA 14-30 because it also needs a neutral. It's only a 30A configuration, but it's a rare welding machine that needs the 50A of their standard plug. They just make them all the same for convenience.

You can adapt or replace the plug on the welding machine to use the dryer receptacle. I recommend you only do so if you know how to strip and terminate wires properly, though.

Here's one ready to go: http://www.kmstools.com/century-wire...ter-cord-10273
