I believe the issue was that it was a 240 welding outlet wired without a neutral or the neutral was corroded or bad. Since a 240 welder does not use a neutral, the circuit would not show as bad when the welder was used.

240 is NOT 240 when you actually need 2 phases of 110.

The camper is not wired for 240; it uses two 120 volt circuits. Those two 120 volt circuits require a solid neutral to complete the 2 120 volt circuits. Without a neutral, the converter panel will make a 240 circuit through the neutral buss inside the converter (where all the camper's white wires are connected). This will put 240 volts through any 120 volt items connected and (sometimes) on when power is applied.

Final update on the 50A 240V sauga. My friend did use the 3 prong adapter to plug into the welding outlet. And on further inspection it does appear that the frigde is not working on 110V. Originally they had a fuse they replaced, he took it home and plugged it in (correctly) and this morning the frige is not working on 110.

All in all a tough lesson but one he won't soon forget as BombDoc says.

Thanks for letting everyone know what happened. I hate it for him, but the sting will fade, and he'll enjoy his trailer.
