When MIG welding on a car, do you have to disconnect the car battery? and if so, why?
Thanx
Thanx
What is more important is proper placement of the return/work lead. I have repaired cars where someone grounded a welder to the frame then welded the exhaust. As the exhaust is rubber mounted and then usually bolted to engine with rusty bolts, the only return path is though the oxy senor and the ECU. This type of issue is main cause of damage due to welding
i had a friend weld a bumper on my truck...he forgot to disconnect the battery. It ran fine on the trip home, but the next day i was having some serious electrical issues. After putting in a new battery and alternator, plugs, and wires the truck still dies (slowly) when taken on a drive, then the battery needs to be charged up again... can anybody help me out?
