The tech was worried about welding on the coach without disconnecting the entire electrical system.  What are the rules if one wants to weld on our coaches?

Good question. If I were welding on my own engine I would disconnect the house and engine batteries, Unplug the ECM and put my ground cable for welding on the engine component I was welding on. I have done it on trucks and non- electronic engines, but never on a computerized coach.

To be really safe, unplug from shore power, disconnect ground on batteries, unplug both engine and trans computers. Put welder ground close to where you are striking the arc. Lots of people don't do anything but...

I bought a Miller 200 wire feed back in the 1970's and have hundreds of hours on it. No repairs but just replaced the CO2 regulator. It makes a lot of the bulkhead welding EZ.
