Remove the metal strain relief, turn it around, then screw it together. I
had to do this with my spot welder.

The following may not make any sense, but I'll try anyway.

The clamp on your plug looks like this right now:

You want it to look like this:

I recently bought a used arc welder that runs on 230V AC, 60Hz, single
phase. It did not come with a male plug, so I purchased one (see
http://home.cogeco.ca/~dmikula2/P1010590.JPG). Unfortunately, the
diameter of the power cord on the welder is too small to be clamped
down by the male plug (see
http://home.cogeco.ca/~dmikula2/P1010591.JPG). Also, the female outlet
I was hoping to use requires 4 prongs (see
http://home.cogeco.ca/~dmikula2/P1010592.JPG). Can I buy a 4 prong male
plug and use it in this female outlet? If so, how would I wire it to
the welder's power cord? Why is the power cord on the welder so thin
compared with other heavy appliances in my home such as the dryer cable?
