not sure if this is in the right category but here we go.


I have a ****** old isuzu i wanna weld a rollcage on to it.. nothing pro, just practice.

What do i need to do before i start welding on the chassis?

disconnect battery im assuming but what about the gas tank?
are you supposed to drain the gas tank every time you weld or is the spot your working on the only hot spot(electrically)?

current takes the shortest path so i don't see why it would fry anything so someone answer my question. Thanks

you are fine but if you are doing extensive welding or cutting, it's best to remove the tank

ah thank you. I thought so. What about the battery? I just wanted to weld a few plates in the back bed so i can later on add some tubing and build some sort of contraption... maybe instead of a roll cage ill build a catapult.

can you picture it?

most people build of the rock sliders on the side.. never weld to a frame

thats ****in sick


removing the gas tank wouldnt hurt. draining it would be a bad idea. an empty gas tank is more explosive than a full one. gas more explosive than liquid

i guess i had my idea based off car rollcages and not truck cages. im not an expert welder by any all means, im prolly not even considered mediocre but i gotta start somewhere.

Disconnect the battery. As far as the gas tank is concerned, just make sure that where you are welding is not going to get the tank hot. I have welded on newer vehicle with the battery connected with no issues, but that was on the frame. Welding on the body may have a possibility of hurting electronics, I doubt it, but disconnecting the battery is a good safeguard. You can buy welding blankets is there is anything that you are afraid is too close to where you are welding and may get too hot or molten metal may drop on it.

Here's a welding blanket:

if its a new vehicle its wise to disconnect the computers, as they tend to fry easily. you can weld with the battery fully connected, but just to be safe disconnect it. welding isnt hard, just throw some tack welds to hold it together and give it hell around the pipe. its good fun.
