read what happens when 220 volts is wired to a 50 amp RV service...
I know a person that did that to a NEW Georgetown....
The general point is reasonable (and valid), but all properly wired 50A RV service is 120/240 split phase service or, pretty rarely, two phases of a 120/208 three phase Y service. The problems usually arise from wiring 30A RV service to 240V rather than the proper 120V.
Welding generally involves comparatively low voltages and quite high currents. Problems, as I understand it, are more commonly due to induced currents in nearby conductors rather than zapping with high voltages.
