Mig/Tig welding

[dna9656]

I read/was told to be very careful when doing any kind of electric welding on Computer controlled vehicles (OBD 1 & 2) because the weld current can go places that's bad for the vehicle. So if this is true  (I have no doubt it is) how do you set up a (2004) OBD2 GM vehicle to safely weld without blowing a computer or air bag?

Disconnect the battery when welding on vehicles.

That's all I ever did.

yep just disconnect the battery, most shops doing exhaust work don't bother and have no problems but all it takes is that 1 time and you will wish you took the time to do it

My exhaust guy put the ground on the exhaust while welding, never a problem. The last one was my 2014 my first was my first car in 1973. After 2014 who knows?
