Since most welder receptacles don't have a neutral, there is no safe way to connect to them even if you wire an adapter. The ground & neutral should be separate wires; combining them will create shock hazards both in the RV & from the ground wiring between the RV & the source.
Trying to use the RV without a neutral will result in unusual voltages on the two legs - depending on the loads on each leg you could end up with a couple of volts on one & almost 240V on the other.
Attempting to use the ground as a neutral will put the neutral voltage on all the bonded metal between the RV & the source - not only a shock hazard for you in the RV, but also for those that touch plumbing, heating ducts, etc. In other words, unless it is a 4 pole connector wired with separate neutral & ground connections, don't use it.
Thank you....someone that understands electricity and the different ways it can be wired.
