Again, old school I always disconnect both feeds to battery. Why chance it?
That allows the electrics to float at high impedance so making it MORE vulnerable if you believe that there is *any* problem. If you must chant incantations etc, at least bolt the negative and positive feeds together.
Do you remove the tyres in case a weld blob punctures one?
No but i remove any tyre that might Tyre blowing up next to your head or chest could kill Folks underestimate the forces involvedThat allows the electrics to float at high impedance so making it MORE vulnerable if you believe that there is *any* problem.

a tire blew up on the dustbin wagon outside our house fortunately the guy was at back of wagon . it blew the mudguard clean off wifey rang me up at work and told me . I was working 3 miles away and I heard the bangNo but i remove any tyre that might Tyre blowing up next to your head or chest could kill Folks underestimate the forces involved
This is my first post, so apologies if I’m responding inappropriately, but if the ignition switch is turned off, haven’t you isolated the battery? Everything goes through the ignition, doesn’t it?
Welcome aboard.
No, things like alarms and many other electrical bits & pieces may depend on having permanent supply - although perhaps not necessarily at full power.
I'm sure some of our vehicle technician Members will be along to advise better than I.
Most control units in any any modern car will have a constant power supply and the ignition will just supply a small current to switch on the unit or will supply one unit with an on signal and the rest will be switched on via can bus or something similar

Haha. Strong opinion by that guy
Yes but is his opinion/advice just wrong or foolhardy? He does say that he doesn't weld for a living too.
From what I've known, removing battery/alternator leads has been preached and done by many for donkey years, have all those folk really been wasting their time?
Now vehicles have even more sensitive electronics, it makes sense to me that those could be easily affected by the process of electrical welding. Personally I don't think that it's worth the risk.
