Per I-CAR curriculum: “Vehicle Protection - Induction of current or voltage spikes can destroy sensitive electronic parts. When welding, protect computers and other electronic parts by:

  • keeping the current path short by placing the work clamp close to the weld site.
  • disconnecting and isolating both battery cables. Remove the negative battery cable first.
  • keeping the machine as far away from vehicle computers as possible.
  • not allowing cables to pass near computers or sensors.
  • removing computers or other sensitive electronic parts if welding closer than 300 mm (12").
  • covering glass and other areas of the vehicle with a welding blanket."
