The R V 50 amp plug has 4 prongs. 2- 120 volt hot, 1 ground and a neutral.
A modern welder plug has 3 prongs. 2- 120 volt hot, and a ground, NO NEUTRAL.
Some older welders had a 3 prong APPLIANCE plug, which had 2- 120 volt hot and a neutral, but NO GROUND.
Clear as mud??
Anything that will run 120v will need a neutral. Newer welders and equipment that have digital displays or controllers will sometimes use a four wire connection so they have a neutral.
I wired all my 50amp outlets in my shop this way just in case... Most just use a three wire plug but I pulled all four wires for this reason.
