Arc Wedling?

[Bill R.]

put the car on a lift and try to clamp my welder ground right around the area that i was welding the patch in from underneath. And as you know you can pull all the computers in less than five minutes, so it wouldn't hurt to pull the ccm and lkm as well.

OK,I am assuming the guy I plan to have do this job is an experienced professional body restorer. There are a half dozen big old antique Mercedes Benz's in the yard he's restoring as well as other modern cars and from talking to him he presents himself as a quick minded individual. That being said I will be asking him to rehab the hole thru the floorboard directly under the base of the accelerator pedal. He removed the pedal and saw how the two tabs on the base piece had been welded on to the floorboard and that he would weld a piece over the cleaned up original and weld the pedal base piece to that . I will discuss with him somehow fitting another piece from below the hole to prevent the Elements from affecting the space between the new covering piece and the original floor THRU the opening if it is only covered from above inside the car. The exhaust pipe off the header goes directly under this hole and dropping the entire exhaust is something we hope to be able to avoid. I was wondering if it will be possible to weld a piece placed from beneath slipped in under the exhaust pipe and held in place by some means to be welded along the rim through the hole from above FIRST then weld the top piece over that effectively sealing out the elements from entering via the otherwise open underside? That being the plan,knowing the area where he will need to work,providing the seats will be removed,center console out and carpet folded back Would you expect he will have the place to ground within the Three Feet instructed in the manual there Meaning if he will we can proceed safely with just removing the negative battery cable and the DME and other Control units in there and I suppose the CCM and LKM over in the Fuse Box should come out too.

On a side note my Radio turned up fried after I had my Car painted. The shop acted completely puzzled about the possible cause and never really offered to do anything for me. I ended up just buying another off ebay for $120..

In setting up an appointment to do this,Sept 22, he mentioned he'll MIG weld and clip the ground inches from the work spot and said there'd be no need after removing both battery cables to hen also remove anything else like DME, or other modules that he works on modern cars all the time that way never had a problem... would you still remove these items or will I look like an over obsessive kook if I make a point of doing it before he begins.? The thing is he's letting me hang around while he does it. I'll be removing the interior pieces, seats, console, carpets etc. so I can remove them if its necessary . I'm just seeing slightly conflicting ideas.. Attack Eagle suggests there's not need because there's no potential in these items to draw current to them and the output of the welding wouldn't ever reach a level to send surges off to every corner of the car so..naturally I don't want to perform unnecessary steps but neither do I want to assume there's no need.. Sorry If I'm essentially asking the same question over ..I didn't know the exact method of welding he would use so wondered if knowing it'll be MIG made a difference.

Pull them anyways, any mig welding produces a ton of high frequency radio waves I wouldn't want 10 feet from my car.

seen ecm's fail on cars after welding was done. All the car manufacterers tell you to remove them, they obviously have valid reasons for doing so. Kinda like removing the battery cables and disconnecting the airbags and removing the steering wheel before pulling the dash cluster

why don't you just tell him that your radio died after the body shop painted your car, and that you don't want to take a chance?

wow, I guess mine should fail then, since all I did was unplug the battery before I pulled the cluster. I think i once pulled the column without even doing that much too.

[Bill R.]

wish, it doesn't mean that others should follow your example. Why take the chance when its so easy to remove them. I seen numerous posts on here about people who srs light is on simply because they didn't follow simple directions and remove it correctly. Its a no brainer to do things correctly and avoid problems.
