is it safe to weld a manifold while its on the motor in the car? i have one leak in my manifold right on the back of the plate i was gona try to get it welded somewher, just a 1" bead, then i thought maybe hooking up a welder to it on the car would fry some/all the electronics ?

 

i read on one of jeff's build pages that he welded his downpipe while it was in the car, shouldnt ---- anything up.

i hear only if you stand barefoot in a puddle while you do it tho.

 

the welding voltage isnt going in your +12v, its going in ground. aka getting ground out.

 

Unhook your battery, and hook the welding ground directly to the manifold, and you will be fine.

 

 

gunnar get your noghole back online, my hf mig is getting ordered in the next 7 days

 

check your pms ******

 

you could always unhook your computer too.....

 

I've always welded stuff on the car. Never had a problem.

 

I only think the only way you could have problems is if you clamped the ground on one of your harness grounds or something of that nature. Just do like they say. Electricity take the path of least resistence. Clamp it close.
