Good idea to disconnect the battery. Look for anything flammable on around the other side of what you are welding.

yes you should disconnect the battery when ever you weld on your bronco. you could damage your pcm and sensors if you dont.

Welding floorboards? Watch out for fuel lines, brake lines and wires !!

. . and disconnect the battery just to be on the safe side. :thumbup

Yes I would disconnect the battery. It is a must on PCM vehcles, but I would also on carb also. If welding with DC (mig) and loose your ground it could run through the battrey and blow it up. Dont laugh it happened at my buddys shop.:enforce

You probably won't fry anything if you don't. Still, better safe than sorry.

I agree with the rest about the disconnect...but we have built a custom bumper and welded all my sas stuff on without disconnecting anything and I haven't had anytrouble...

As scared as everyone is about the battery, you really don't have too, if you don't want too. Keep your ground clamp close to where you're welding at, and you'll be perfectly fine. When I fabricated my alternator support bracket, I left everything connected, so I could tack weld my pieces together. Battery was still hooked up, alternator was still connected. In fact, I had to use my alternator to help with the mock up of my bracket, so I could be sure I got everything right. And I was only 2" away from the alternator, when I made the tack welds. Why is my truck still running then? Not only do I not have sensitive electronics, but I also put my ground clamp on the other side of my alternator

Everyone knows that electricity follows the path of least resistance. With my ground clamp on the other side, and still close, I was able to safely weld on my truck

However, ct makes a good point about the fuel line
