Messages 5,486 Location Glapwell, Chesterfield, Derbyshire, UK Jul 19, 2019 #4 I use a surge protector that is clamped across/on to the battery terminals. Even when I'm using hf ac tig, welding aluminium cages or booms, not had a problem with an ecu. Just make sure the return cable is close to the welding area...

grim_d Unlikeable idiot. Messages 4,220 Location Scotland - Ayrshire Jul 19, 2019 #5 IMO it's quite simple. Electricity takes the path of least resistance. If your return clamp is situated right next to the area you are working it can only go down that. Don't clamp your return onto the negative battery post. If you are worried use a surge protector as above.
