Are inverter mig welders safe on car ecu's
more modern ECU's are well shielded for EMC but the early ones were not and know of a few that went pop in the early days.never ever had to use one,if ya worried,disconnect the battery
In fact,i've never known any ECU to get knackered on any of the motors i've welded
also,somewhere on here one of our very clever members have proved it all a myth(their name now has gone from memory)
OK,thanks,erm which motors would that be?more modern ECU's are well shielded for EMC but the early ones were not and know of a few that went pop in the early days.
If you stick 40v up a 5v system it dont like it.
Remember the Mk3 Escort with the fuel injection (RS1600 & XR3i) know of a few that died after welding. all of the early Fords were a bit touch and go.OK,thanks,erm which motors would that be?
Agreed,but as said,before,remove the battery,if in doubt,but yer,some dont think of that,lolRemember the Mk3 Escort with the fuel injection (RS1600 & XR3i) know of a few that died after welding. all of the early Fords were a bit touch and go.
the RR 2.9 EFI with the ECU under the seat with people welding new sills on was another.
I'm sure I've put this before many moons agonever ever had to use one,if ya worried,disconnect the battery

I used one of those and still got footprints in the butterI had a concern about elephants taking up residence in my 'fridge'. I noticed that there was a special house brick being sold that prevents it happening, so I bought one. I haven't had a single elephant in my household appliances ever! Marvellous these special house bricks.
Thanks. I was only asking as had a peugeot 309 to weld up and it fritzed the ecu battery was disconnected also
Co-incidence.
Had one fry on a daf truck when welding rear tailgate on aluminum body whether it was related to the welding or not is negligible as it made it less than a mile after welding before complete ecu failurenever ever had to use one,if ya worried,disconnect the battery

Vehicle battery is a pretty good surge suppressor for absorbing low frequency surges, so disconnecting it will remove a good bit of protection.
What it's not much good at is supressing high frequency transients, which is where a decent surge suppressor could work, however the surge protector will only protect circuits that have a permanent 12V feed, and you can still get transients through all the wiring.
So as has already been mentioned, make sure you have the earth clamp as near the weld as practical.
