Welcome. My name is XXXXX XXXXX would be glad to assist.
You are trying to connect a 3 wire welder to a generator?
and what do the slots look like, there are 2 on the outside and 2 in the center top and bottom
or if you can read the number on it, like L230P
3flats &1WITHLEAG IN CURAL
look on the face, there is a number
ok, see the X and Y? Those are the 2 power wires. The G is ground wire to the welder. You will not use the W position
welder only uses power and ground, doesnt use a neutral
You are very welcome. Glad to be of service
