Actually you were correct and I was wrong. I took the 220v column. I should have used the 230v column.
47.5a is the input. So the suggestion to use a 50 amp circuit and receptacle is a good one.
The only thing I would do is use "standard" wire sizing as I said before. I do NOT like to use the NEC special permissions for welders and motors in residential settings.
You never know. The next homeowner may plug a kiln in to that 50 amp receptacle.
Wired with #12 as the instructions state would be a real hazard feeding anything but a welder.
