TIG Welding on a car

by Mark

Most cars are quite electronic with a computer, etc.. I want to weld a hindge back on to the driver side door of a Jeep Cherokee. Do I need to disconnect the alternator, and battery before welding? Do I have to ground the onborad computer before I TIG weld on this Jeep? What is the correct procedure?

---------------------------------


i would disconnect the battery and attach a ground as close as possible to the weld.
you can do this by grinding an area on the hinge to clean bright metal and wrapping some bare copper wire around it or tape the copper strands to the bare metal and attach you ground clamp tho the other end of the bare copper strands.
