    ...very large voltage spike that occurs unavoidably when the arc is switched OFF.
    Thanks for taking the time to explain the details. That makes a lot of sense.

    I've also read that the hi-freq starting circuit on TIG welders may wreck electronics.

      that is one sweeeeeeet looking bed man ! you must get a lot of compliments on that babby.
      that hole relerning thing is just stupid, what a $.50 battery to hold the menory was just too much to add to the original design????? just more POOOOO to make you think you have to take it to the dealer for any and all work on it.
      thanks for the help
      ......or..........
      hope i helped

      summer is here, plant a tree. if you don't have space or time to plant one sponsor some one else to plant one for you. a tree is an investment in our planet, help it out.

          YEAH STICK if at all possible dont take any chances. cost to $$$$$$$$$.
          disconnect that batt. Itll make ya happy in the long run pocket too.
          i waas taught that any vechicle especially construction equip the batt should be disconnected prior to welding.
          Call up CAT GROOVE TENEK. that should help also.

                wow hard to believe no one has mentioned how cool that thing is. i'm not a big fan of the ford's myself but i know a cool looking bed when i see one.

                  Ah! LMAO , me neither especially after owning this one. Try keeping the intercooler hose on the turbo when hitting 30+ pounds of boost. Ford can’t seen to do it , so this is how a bridge / dock builder does it. Not pretty, but hasn’t come off since! Note the exhaust clamps, and turnbuckles.

                      LOL gotta do what ya gotta do, but it shore would have been nice if ford would have taken care of that befor they started selling them.
                      well atleast it looks cool.

                        Can someone explain how a surge protection device would work? I can understand how it would work on my computer as the flow must go through it to get to the computer but on a machine/car there would be multiple paths for it to get to the electronics wouldn't there? If I'm welding on the frame & have a surge protector on the battery couldn't the surge just follow a path through where the electronics are grounded to the frame? I know I'm missing something here.---MMW---

                          "Better safe than sorry. Usually I keep the ground clamp real close to the weld if I don't disconnect the batt. If I do disconnect the battery I just hook up a 9 volt battery to the vehicle's battery leads, this will keep the memory in the computer so there will not have to be a relearn. This is how I do it at work on fleet trucks (most of the time). "
                          I see,,, so we take one battery out and install another one? There is an explanation that made sense a couple of years ago on this board and the conclusion was to disconnect the + lead. I dont remember all the details. I have welded on hundreds, maybe even thousands of pieces of equipment and never removed a battery, not once for welding unless it was on the batt box. I ask my engineer about this and especially with common equipment he says no reason, none. What really does catch my attn is that newer cars have so many plastic parts that wire harnesses have complicated interconnected ground wires within wiring harnesses that an alternative ground loop could occur within the harness.

                            That is what I am having trouble understanding.
                            And also, Why would disconnecting the ground cable from the battery have any bearing on the effects of welding current?

                            So, if you are welding on a structure and are in the vicinity of a variable frequency drive for an electric motor, now what do you disconnect?
                            So far we have not fried any drives and they are a sophisticated electronic component..

                            BTW, I weld on the back of my Fords and have never had a problem.

                                I know a couple equipment dealers, one with new trucks and they dont either, body shops too. I am not realy qualified to ssay not to do it but this thread is more about the need to do it. It can create a lot of potential problems and dangers fooling with batteries too. As for burning up parts and fuses, well, sometimes its suprising how many coincidences there are with guys that work on equipment daily, and a lot of that doesnt have the greatest wiring etc to start with. I could have assumes we put a fuel guage out the other day from a weld job but when I checked the operator said it had started acting up earlier. I had a switch just up and die the other day when we did something on the other end of the tractor, had been working for years. Here is another one that happened not too long ago. My auto mechanic Bud brings his wifes car over for a little frame repair, a localized thing in the rear somwhat near the fuel tank and difficult enough that he didnt want to do it himself. So he is about half jagged anyway and has been working on this car, well I fix the spot, its a job well done and half way the 5 miles back to town somethin is smoking and on fire. He calls up, hey,,, you wrecked the car. I said, well maybe so but I looked before I did the job, a couple times, no wires, no lines, no fuel or vapor lines and I ground right on top of the work, he had extensively rewired this car so,,, maybe something got caught up. Next day he sobers up, goes to investigate and calls me back about noon, whoops, left a couple wire ties off it seems and the thing comes down on the exhaust. 5 minutes after I work on it another problem in the same physical local, go figure, without some real forensic work we could have jumped to what would have been likely the obvious.
