welding manifold on car
 

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.

Re: welding manifold on car
 

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 faggot

Re: welding manifold on car
 

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

Re: welding manifold on car
 

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

Re: welding manifold on car
 

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.

I usually unhook my ecu when welding on my car....

Re: welding manifold on car
 

You're simply a moron..... Ground close to area of welding means the current isnt jumping through the electrical system. Unhooking the ground on the battery works better than unpluging the computer. You still leave the radio and every other componet left with the chance of possibile damage. You need to find a new place to go to school where your instructor is the biggest retarded nig nog.

i almost always weld parts on the car. never had a problem

Re: welding manifold on car
 

;)
But you're wrong! BRIOHATCH is the god of welding and knows everything about TIG welding stainless He must be right on this one...... ---- nut

Re: welding manifold on car
 

Just unhook the bat, and the ecu. But I welded on my car last week with everything hooked up and had no problems.

Re: welding manifold on car
 

sorry nig nog, what was i thinking

BRIOHATCH :bows down:

Re: welding manifold on car
 

i always thought that when you weld on a car just make sure the path from your ground and your electrode just cant have any electrical circuts in between. if your welding current dosnt pass through anything youll never have a prob, battery hooked up or not, i would imagine. but not knowing 100% i just unhook it anyways, but theoretically you dont have to.

Re: welding manifold on car
 

:y but unhooking the bat ground is always the best thing to do.

Re: welding manifold on car
 

i usually only unhook it when i am removing the battery, or engine

Re: welding manifold on car
 

I always thought that welding created a large magnetic field . I never looked into it and I have never taken out my computer when welding on the car, but I always stayed away from it (it's under the hood) incase the field could damage it.

Re: welding manifold on car
 

you can weld on that fucker all day long. computer, battery and every other damn thing you want plugged in.no current is flowing through your computer or anything else. you are jumping an arc from your frame (negative) to gour welding lead (positive) you will not harm a thing.

Re: welding manifold on car
 

All day long?? maybe even for a year, but the next time you weld on the car, it could be 5 minutes later that you burn up the ecu. Copper wires create less resistance than the carbon steel frame will. What if you are welding something and the current finds its path of least resistance is not all the way around the frame, but through a ground wire that runs to the ECU?

Play it safe...unhook the battery and ground close to what you're welding (directly to it if possible). It can't hurt to unhook the ECU, but it should have it "out of the loop" when you unhook the battery...at least that's my logic.

Re: welding manifold on car
 

unhooking the battery will have no effect. the ecu is still grounded to the car even when the battery is unhooked. i have welded plenty of times without any problems, but if you are that worried abuot it then unplug it. im sure most of us have our ecu's sitting on the floor anyway. thats where mine spends most of its time

Re: welding manifold on car
 

The welding current can just as easily go through the positive lead to the ECU... in other words, unhooking the battery makes sure that there's no complete circuit that the welding current can go through. Correct?

Re: welding manifold on car
 

I heard if you TIG on your engine when the ECU is hooked up it will make your car faster. I think that's true cuz my buddy did some TIG on his crx and its runnin 9's and beat a ferarri.

Re: welding manifold on car
 

mig will only get you into the ~12 second range

Re: welding manifold on car
 

what about stick welding? at least low 14's?

Re: welding manifold on car
 

high 13 low 14's

didnt you know? my toyota ran 14.3 with full stick welded exhaust O0

Re: welding manifold on car
 

damn, i gotta get a bottle of gas for my mig, betwen the tiged charge pipes and a miged exhaust i should be dipping into the 11's

Re: welding manifold on car
 

Damn I guess I should run 9s
