Welding on exhaust? Safe?

Is it ok to weld on my exhaust, wire feed welder, 120v, to add a bung for a sensor? Did this to my 7.3 without issue, don't want to mess up my truck though...


Thanks!

You are fine to weld on your exhaust. No problems. If you are just welding a bung on, then get after it, if you are going to weld your whole exhaust together, I wouldnt do it just in case you ever have to go back to stock.

Just disconnect the Batteries to be safe. It could hurt your electric/PCM.

Since this is brought up and scaring me, I'm getting ready to put my traction bars on and was gonna get a friend of mine to weld a few spots on the frame mounted bracket so I don't have to worry about it wiggling the bolts loose but I guess if it runs the risk of hurting electronics I don't want to risk it. I've had enough electrical issues with this can/bus system.

Anyone use those surge protectors that go on your batteries to weld on a truck/car? Would you need 2 for our trucks??

Disconnect the batteries and keep the grounding lead as close to the weld as possible. That will keep the welding voltages from traveling all over the place.

When I had my buddy help me put my traction bars on, he did actually weld them in place to make them sturdier at the frame. We did not disconnect the batts, though I could've just been lucky.

I have too, but it's nice to not have to reset all my satellite radio stations and other settings...but your right its not worth the risk at all, if a surge protector will save me that would be great. Maybe I can throw a battery tender in the cigarrette lighter and keep all my settings?
