Welding Precautions

[Whaler]

I decided to replace and upgrade my house{four} battery rack. A local shop is making a new one and will weld it in place. The location is a fire safe and easy access area. What precautions should I take prior to welding to protect my motorhome systems?

I don't know ANYTHING about the area you are welding but a couple years ago DH had to weld the bumper on the 5th wheel. He put a sheet of metal (I think) against the camper, and I hosed the camper while he welded. I told him not to set himself on fire because I did not want to make the decision whether to protect the camper of him... joking.

Disconnect the coach from shore power. Keep the ground connection for the welder as CLOSE as possible to the area to be welded.
Make sure that there are no wiring harnesses, fuel lines, propane lines, air lines, near the area to be welded.
Some people may recommend disconnecting the batteries, or ECM/TCM but I never found that necessary on any of my coaches.

Unhook batteries and shorepower.
