What voltage is the welder,
There should be a plate that states its voltage,
Is it 120v or 220v ?
What color are the three wires on the welders power lead ?

If you are trying to plug into a 4 wire dryer receptacle, it will not work.
You need to run a new circuit to match the welders requirements.

Or he could make an adaptor and drop the neutral

Welder circuits are "special". See NEC 630. You might be able to use the dryer outlet, but you need to determine the current requirements and the duty cycle of the welder to see if your wire size and breaker are adequate for the welder. You can make the plug match by changing either the outlet or the plug, but you need to review NEC 630 for wire size and breaker requirements. Also, if the breaker size needed exceeds the NORMAL breaker for the wire size for a branch circuit, the outlet MUST be labeled "Welder Only".

Don't get me wrong, I am NOT an advocate of applying Art.630 to a residential setting, but can you tell me where in the code book you find this "welder only" label requirement?

Install a 4-wire dryer cord on the welder. Connect the green wire to the welder's ground, the red and black wires to the welder's hot terminals (which might be color coded red and black or red and white, doesn't matter). Do not use the white wire from the dryer cord; tape it off or wire nut it.
