Can I safely weld on my 1993 dodge dakota without removing the computer? What should I disconnect before doing so?
Thanks

You'll probably be fine, but it should be easy to remove if you're worried. I welded an exhaust mount onto my '00 without doing ant damage to mine.
Lead, follow, or get out of the way

You should always disconnect the negative terminal to be safe. Not a big deal.

Tail pipe/ muffler shops weld on all types of rigs and never disconnect nothing. the only electricity passed is between the 2 welding leads. Just think a minute. When your welding, your always touching the part your welding. You do not feel nothing. There is no current passed on other then between the leads. You do need to watch where the welding sparks are going and heat transfer to sensitive parts.

"the only electricity passed is between the 2 welding leads." This is incorrect, and often no damage occurs, but it can blow the electronics. There is the chance of raising the potential of the car higher. Why take the chance? It only takes a minute to disconnect a battery, and $300 to buy a new computer. But hey, it's your wheels.

Bob, with all due respect, if what you say was correct, When you was weldind metal, it would be like an electric fence. Now if you was to hook the ground at one end of the truck and weld at the other, there would be electricity traveling all this distance. Just keep both in the same area and this is as far as it traveles. Now if a person was to hook the ground to the body and the welding lead to your electrical components somewhere I would agree. Fry time. As it is your hooked up with both leads to the same negative metal so both are hooked to the car ground. Can't pass it to the electrical side. You absolutely need both positive and negitive to create a live electrical field.
So many problems .... So little time

I agree with Lincoln. The muffler shop disconnected the negative terminal before welding on mine. They ought to know how to avoid buying computers.
Think about it, you can't see the electrons move so you have no idea where the electricity is going! It follows multiple paths of least resistance! Try welding in the rain and you will learn about this!

I'd assume it only travels where the ground is placed to the actual welding. And when i did my exhaust I grounded to the exhaust to weld the exhaust.
Maybe I got "lucky" but I must have welded for 3 hours to get my exhaust together. Didn't unhook anything.
Most ppl are more worried about grounding in the WRONG place and passing the current through BEARINGS. But if you connect the welder ground to the exhaust, while welding the exhaust (for example) it should not hurt anything.
Static charges throughout is another thing entirely. But the PCM should have plenty of protection against that anyway.

The only time you really need to unhook the battery for welding is tig welding...since there is a certain frequency that will disrupt your computer.

I called our by far biggest muffler shop in town just now and poped the question. they us wire feed welders and NEVER disconnect the battery. They have never done dammage to a cars electrical system of any kind. This shop has been in business for many many years. they also stated they weld a lot of other things on cars (mostly 4x4's with under carage damage). Seeing as removing your battery ground cable is a simple thing to do, if it makes you feel better then by all means do it.

I have done a ton of welding on my TPI Firebird and I have never disconnected anything. No blown computer, alternator or anything like that. I think its pretty safe. If there were problems with something like that im sure we would have heared about it by now since FI cars have been around forever.
