What happens if you plug a 50 Amp RV into 22V welder plug

Have the proper plug installed, whats it going to cost really??? you bought the rig and payed how much, now don't take a short cut when hooking it up
the best way to do this is hire an expert, someone who is licenced with a business and insurance so if he smokes your rig, his insurance will fix it.
if you smoke it who pays to fix it?


dam!! I have "3" 30 amp RV plugs around my place
