What do you unplug before Weldin

I am about to weld a tag box on the back of the car. What should I unplug before I start welding because I dont want to fry the computer. Can I just unplug th battery and that should do the trick

Holy...

We have a thread about this going on already. Sometimes I dont get on people about it, but when its a few threads down, I will.

Closed. Look at the other thread.
