They are not concerned about the weld quality, it is the electrical effects on components in the car they were questioning. I have been reading for 157+ years!
Yeah some dumb *** might ground the welder to their electronic ignition module, their transmission, engine block or drive shaft? Those guys don't belong under a welding hood!
I don't know anyone who has messed up their electrical system by grounding to the chassis when welding on the chassis front to back. Lol
Most on here don't work on their cars and repeat what they have read or heard. I go with the latter, guys that actually do it like me. You can learn a lot from a dummy.
