I'm about to modify my shocker mounts for longer suspension travel and need to do a fair bit of Migwelding on my chassis, at each corner.
Have 1239E controller, HPEVS AC51 and Zeva BMS , I'll disconnect the 12V battery, Traction battery will be isolated via maintenance contactor .

Any other special precautions required ??

Obviously I'll be attaching the welding clamp on the parts I'm welding to the chassis !

This is what I have done for small welding jobs. Please post back if you notice anything else going on after the work is done.

Ok all Welding done , I didn't disconnect anything , I figured leaving the battery the 12V battery in circuit was good protection as it would absorb errant spikes.

No problems. Everything still works !
