Noob welding question

First of all I know zilch about welding. A guy I work with says he knows how to weld and would help me weld up a roll cage. We have been working on ideas over the last week or two. I would like to weld the cage directly to the frame. Is there any problems with the electrical system that I should know about before I let him torch it up? He is concerned that with the current used in welding the cage to the frame that it could fry the wiring. Is he crazy? Should I just pay the $$$ to have a welding shop figure it out? Sorry for the stupid noobie questions. I tried a search, but couldn't find any answers to this specific question. Found lots of other answers though. At least I am learning.

If you are worried about the computer and other electronics, be safe and dissconect your battery. If you are welding near parts of the wiring harness make sure you don't melt anything. Other then that watch out for fuel lines. Good luck

Yep I agree with 90TOYPU, disconnect the battery everytime you weld on the truck. A lot of guys on this forum says otherwise but I wouldn't listen to them. Hey better be safe than a fried computer!

Disconnect the negative and you should be good. I've welded on my frame more than once without problems but it doesn't hurt to play it safe.

Anny time you weld on your rig you should disconect your battery... I myself have been guilty of forgetting to do so, and as a result i have burned up 2 MSD ignition boxes...

As said, disconnect the battery first just to be safe. Also, get a scrap of sheet metal to use as a heat shield when you are welding near fuel lines/wires/etc.

The "A guy I work with says he knows how to weld" has me a bit worried though. I would be checking out some of his welding work before having him do something serious like a roll cage. A guy I hit the trails with had a tow hook welded onto his frame by someone that "says they know how to weld". The first time we hooked a strap up, the hook broke right off and left a huge dent in the truck that was pulling him out.

Never weld a hook to your vehicle. I have never seen one hold up.
