Welding With Battery Connected. Therefore the ultrasonic welding may be evaluated as not ideal for welding of cylindrical. However it may be less suitable for the particular application battery welding as it was found to have a high heat generation and thus substantial heat input into the battery.
With the battery connected there is a closed electrical loop where the voltage across the vehicles body could add to the batterys voltage and cause an overvoltage condition at the ECU. Changing welding helmet batteries might seem challenging but with knowledge and practice the task can become much more manageable. For the welder to push current through the body it must impose a voltage across it regardless of how good your earthing is Ohms law.

Attaching the ground close to the welding operation is best practice. I never saw any on disconnecting the batt for spike issues.

It has been many years since I worked as a service tech.
