Default Mig welding on generator frame, Damage to electricals?

I have a Dayton/Generac 8kw diesel enclosed generator set. The unit is self contained. I wanted to repair the rusted battery rack on the main frame of the generator. I have a Mig welder but I am concerned about welding and any electrical feedback damaging the gensets component boards. Is it ok to weld on it or not?

if nothing is connected to the frame probably not a problem but
engine wiring uses the frame as a return and often
the engine and gen wiring are in the same housing
possibly interconnected [I have one of each]

got a big tip for the O2/C2H2 ???
[and a lot of coat hangers]

Make sure you have good ground contact, and that it is close to the point of welding. This will help diminish stray voltage issues.

On new Big trucks a sticker says to unhook the battery cabels be fore welding to protect electric components. Keep the cabels from touching anything and you should be good to go.
